This is a very much modified version of the Spectrum 'Artist' screen compressor.
 
I have rewritten most of it to make it a lot, lot easier to use as well as more friendly and more friendly by providing 'step by step' instructions during its use.
 
Simply load the compressor then load in your screen$. You can elect to load in a normal screen or a headerless file, the latter was added as it permits you to load in a screen that is shorter than standard length if necessary for any reason too.
 
Once a screen is loaded, the reduced size is shown and you are offered the option to save it or load a new one. Also offered is a simple colour change for the menu itself as its new default is black text on yellow, but a keypress will cycle through other combinations.
 
The code is saved at 28350 however it is completely relocatable (above this address) without further modification. It is generally recommended to issue a CLS after loading the screen code before executing it and ideally the paper and ink colours should be set the same before the CLS but this is completely optional.
 

Enjoy!

JetSet Willy for the Amstrad CPC range of machines complete with cheat options.
 
If you are looking for original, unchanged versions please see here for JSW1 and here for JSW2
 
Two disk (.dsk) image files are provided and one tape version. One is only compatible with the 464 (it is clearly marked) and based on the original release. The other is suitable for the 464,664 and 6128 and is based on the Re-Release. Neither of these retain the keypad protection either.
 
The tape version is Speedlock protected and manually edited directly to provide infinite lives.
 
The disk versions provided offer the following cheat options during game load:
 
Infinite lives: Yes/No
Harmless enemies: Yes/No
 
It should be noted that there is no protection against high falls nor any against fire cells, however given the JSW1 for the Amstrad uses a very similar "safe start" as seen in the Spectrum (and Amstrad!) versions of JSW2, a high fall in most cases will not result in an infinite death scenario unless you are very careless.

'Jet Set 40-40' is a redesign of Matthew Smith's classic ZX Spectrum 48K game 'Jet Set Willy' with a few interesting and unique features!
 
The layout of 'Jet Set 40-40' is very similar to that of the original 'Jet Set Willy', so those who have played the original will feel 'at home' immediately.
 
The number of rooms has been reduced to 40 and there is only one item per room. However:
 
The player has to collect four complete sets of items; once the last item of one set has been collected, the items of the next set will appear. The difficulty of the game will increase with each consecutive set of items, as more and more guardians emerge to threaten Willy's progress through his mansion and its surroundings!
 
The player is offered a choice of rooms in which they can start the game. An option of playing without some of the most extreme challenges can also be chosen.
 
We hope you will enjoy this 'quadruple quadragesimal' challenge!

JSW1 for the Spectrum with a few mild patches present.
 
Care was taken to avoid over-doing any fixes with a few exceptions. The intention being to try to retain reasonable originality but taking a mild twist on the regular '4 poke' fix:
 
1. The Basic loader was slightly altered (see screenshot) , the embedded codes for the flashing and colour blocks were replaced with their instruction counterparts. Care was taken to ensure the ordering was kept the same. The 'crash' poke was left intact but the real floating point value was changed from 23613 to 16384, thus ensuring the 'crash' poke did not have any effect as it was now just setting the first byte in the screen memory to 0 harmlessly. The combi-screenshot shows both original with 'exposed' embedded values and the 'replacement' one. Viewing them in 128K Basic they look about the same, the change is only really apparent in 48K Basic mode, however they function identically with the exception of not crashing if Break is pressed.
 
2. The keypad routine was left intact however rather than change the first JPZ or the second JPZ to just a JP (to always pass the keycode) the reset the machine instruction was changed to start the game instead by just changing 00000 to 34762. This way if both key code entries fail, the code falls though to the 'reset' line but its now going to jump to the title screen instead. This also preserves both calls to the keypad code too, so that both instruction strings are seen.
 
3. As per the official bug fix, the fire cell was removed from the Conservatory Roof. Viewing this screen on both JSW2 and on JSW1 and JSW2 on several other platforms, there is a mild variation in how it is fixed on those, generally it involves removal of one more fire cell but in this case, the single cell removal (although not perfect by any means) was felt sufficient.
 
4. As per the official bug fix, the earth cell in Banyan Tree was changed to a water cell. There are other fixes to this such as modifying the tree 'trunk' and/or the lower 'roots' area however these are a bit too much for a mild bug fix, so the official fix was felt best.
 
5. The self collecting item in Swimming pool, there are various ways to fix this however a fractionally different approach was taken. The most common one is to set the ink to 5 (cyan) however in this case it was set to 4 (green) as this may be a more suitable colour given Orangery is above, aka: a 'Vines' effect and that screen is mostly green too
 
6. The invisible object in First landing, although the official 'fix' moves it, unless further action is taken it is still invisible and it is quite possible to miss it if you are jumping to avoid an arrow. Rather than give it shape/form it was easier to simply remove it from the game.
 
7. The double object on the beach, there are two ways of looking at this. Previously splitting it into two and moving one further to the left so Willy is forced to use the water 'conveyor' seemed ideal however this file is meant to be a mild fix so the best approach here was merely to set it to be just one object not two.
 
8. The pause bug caused by the presence of an Interface1, as per Skoolkids bug fix this was rectified by changing the IN A © to IN A (254) , along with a single NOP for the inactivity counter as well. This does not prevent pause it merely means the game will not auto-pause, the same as if the in-game music is playing.
 
9. The ability for Willy to leap from the top of a rope where he is not intended to such as Beach , On The Roof were rectified by changing his height comparator from 12 up to 15. This usually prevents him climbing high enough to be able to 'jump top exit' while on a rope.
 
10. Thought was given to the guardian halo effect, as well as corrupted conveyors although their fixes involve potentially putting some code into the unused areas, the same as the bug that effects Under The Roof if you happen to fall off. The latter two quirks were ignored and the former 'halo' ones were fixed by simply turning off the bright effect on the few effected sprites.
 
11. The infamous 'attic bug' was rectified using the official method of setting its co-ordinates correctly as this is the most sensible and efficient fix.
 
12. The incorrect animation counter for the Monk/Priest in Chapel as well as the saw in Cuckoo's Nest were fixed by setting them from 03 to 07 and setting their correct starting frames so they animate as intended and do not move 'backwards'
 
13. Unlucky for some ? The slightly annoying effect of the time and item count temporarily flashing back to 000 and 07:00am was rectified by changing their initial display values to be a blank space, leaving the colon intact. This means that they temporarily flick out and back in again however this seems indefinitely preferable to having them appear to have the incorrect values displayed albeit temporarily. There is a small article in our Articles system describing this in detail.
 
14. Finally, the existing bugs/quirks such as jumping from the top of Dr Jones and Watch Tower as well as Esmerelda are left in, as they were in the original file, along with the TRS-Dos code at the end of the file.
 
Enjoy!

The initial idea of this small game occurred to Andy one boring weekend afternoon. It was to make a mini "25 items and 25 rooms" variant of JSW, but after trying this out, in reality it did not seem that much fun. Thoughts then turned to have a grand total of 100 items spread around 25 modified rooms. This involved much demolition and rebuilding of Willy's original mansion to accomplish sensibly!
 
Some of the conventional paths to reach certain items are slightly altered, although the game room layouts are (broadly speaking at least) not too far from the original game.
 
The download .zip contains a standard .tap file of the game as well as a more detailed readme.txt file
 
We hope you enjoy this game as much as we did putting it together and look forward to reading any comments and/or feedback on it.

The initial idea of this game was to take a different twist on the release of the "Manic Miner - Hi-Score Challenge" game, which, although was reasonably successful in itself, did have some quite limiting factors, namely being forced to either POKE or reload to change the cavern, which meant multiple cavern completion times were not possible.
 
With this in mind, Andy decided to make a cut-down version of “Manic Miner”, featuring a mere ten caverns. For the sake of traditionalism the first and last caverns, (those obviously being “Central Cavern” and “The Final Barrier”) were kept.
It was decided to simply create two other, new versions of it based on what we had, so we would have a total of three games. The new ones being an ”easy” version and a ”hard” version. The thoughts here were to make the ”easy” version a little bit more player- friendly than the original and the hard version slightly more trouble for the player.
More details of the changes and details between each version amongst other things are in the readme file.
The download .zip contains a standard .tap file of the game as well as a more detailed readme.txt file
We hope you enjoy this game as much as we did putting it together and look forward to seeing your high-scores, reading any comments and/or feedback on it. We feel it is an interesting slight twist to the original in offering the choice of skill levels to play at.

Manic Miner for the BBC Micro. The conversion was written by D.J.Coathupe.
 
Two completely distinct versions are provided as separate disc (.ssd) images. Both versions feature a bypass to the inbuilt keypad/keylock protection. Simply enter any code or just press Return a few times to have it accepted.
 
1. Filename "Manic Miner Invulnerability" .
 
As the name suggests this provides near immunity during play. This does not provide infinite air, merely immunity to moving and static enemies as well as long falls.
 
Notes: Although the game will not immediately end when the air supply runs out, it will soon crash thereafter if MinerWilly does not complete the cavern within a timely fashion once the air is exhausted. It is also quite possible to stand on fire cells. Some small care must be taken to not jump out of the top of the cavern which again can result in a crash.
 
Both of the above small compromises needed during gameplay are very acceptable within this scope.
 
2. Filename "Manic Miner Level Skip" .
 
Notes: This version does not offer any extra lives, air supply or immunity! It simply allows you to choose the starting level. This in itself is a great boon if you wish to practise a cavern as the BBC version does not contain the ZX equivalent of a '6031769' teleporter routine. The game itself must be reloaded from disc if it is wished to change the level as the patch is applied before the game code is executed.

Manic Miner 2020 - Special Edition
 
This small eight cavern mini game is dedicated to all essential workers in any industry or sector who are continuing to keep things moving during these highly unprecedented times of the 2020 lockdown. We say "Thank You"
The game engine itself is slightly modified from standard, the main changes of note being:
 
The caverns themselves are identical in layout of guardians and cells to the original except they are mirrored versions!
There is approximately a 30 seconds air grace period upon entering each cavern
If the air supply should for some reason actually run out during play the game will continue without loss of a life
The bonus for making Kong fall into the Portal is increased
Pressing Break during play to abort the same will unlike the default Manic Miner update the highscore
 
The caverns to play are as follows:
Eugene's Lair
Miner Willy meets the Kong Beast
Wacky Amoebatrons
Attack of the Mutant Telephones
Ore Refinery
Skylab Landing Bay
The Warehouse
Solar Power Generator
Should perhaps also be noted that both Kong and Amoebatron's screens in the original game are used twice, here the versions used are the second appearance of each as these variants are a fraction more difficult.
We will keep a top-x record of players scores too:
 
:1st: - 41842 - jetsetdanny
:2nd: - 40173 - Spider
:3rd: - 36281 - MtM

Thank you , and enjoy! 🙂

A simple small file to load before the main JSW tape. It provides the following fixes to the standard game:
 
1. The second keypad code is always accepted
2. The invalid arrow in The Attic is rectified
3. The impossible Fire Cell in the Conservatory Roof is removed
4. The single Earth Cell in Banyan's Tree's trunk is replaced with an Air Cell
5. The air ink for Swimming Pool is changed to allow Willy to collect the item by himself
6. The top distance on ropes was reduced preventing Willy from accidentally jumping up where it was not intended
7. The interface1 pause lockup is fixed
8. The hidden First Landing item was moved to The Hall and given a shape borrowed from West Wing Roof
 
It should be noted this is intended for a standard game, its effects on third party variants of JSW is unpredictable.

JetSet Willy 2 'Final Frontier' for the Commodore C64 written by J.Darnell and S.Birtles
 
This is an original tape (.tap format) minus any protection system. It is otherwise unaltered.
 
The game itself plays very well and mimics the Spectrum and Amstrad versions. There are a few extra rooms (an IDS sequence if you jump into the Bathroom toilet) and some names are slightly different too.
 
The 'game over' sequence is completely different and is not too far off what is seen in Technician Ted (Spectrum and Amstrad versions) , there are three pictures of the 'sequence' in the listing.
 
The scrolling message reads as follows:

Disk image (.dsk) of Manic Miner for the C64/C128
 
The .zip also includes a .prg (tape file?) image too.

Disk image of Manic Miner for the Tatung Einstein
 
This includes the 'keypad' similar to the Acorn/BBC version of Manic Miner.
 
The scrolling message reads:

JetSet Willy for the Sinclair Z88. Authored by Dominic Morris.

JSW for the Commodore C16 machine.
 
The tape file is a conventional .tap format.

JetSet Willy for the Dragon 32/64 range of machines. These are tape .cas files.
 
Two versions are included as well as the four page code sheet.
 
V1 tends to ask for the code but the game seems to crash a bit, possibly due to emulation issues.
V2 (recommended) very rarely asks for a code and does not crash.
 
Control keys:
 
Cursor Left / Right = Move left / right
Shift or Space = Jump
 
P = Pause
C = Continue
 
Q = Quieter / Volume -
L = Louder / Volume +
 
Shift +A = Abort
 
The game features a few screens not seen in other versions such as "The Guest Room" , "The Pub" , "Hall Of Mirrors" amongst others.
 
There is also a in-built cheat mode for game, allowing you to move to any room. To do this:

 

JetSet Willy 1 .dsk disk image for the Tatung Einstein range of machines.
 
This includes the 'keypad' protection similar to the Spectrum version of JSW as well as the Acorn/BBC version of Manic Miner
 
The scrolling message reads as follows:

JetSet Willy for the Commodore C16, written by Ian Davison and published by Tynesoft
 
This version contains a reasonable adaptation of Willy's mansion given the memory limitations, there are are total of nineteen rooms.
 
It features the 'square stairs' as per the C64 version although they seem slightly easier to negotiate in this variant. There is no scrolling message on the title screen and very little in-game sound but the general 'feel' and play of the game is quite good, along with sensible choices of sprites being used.
 
Interestingly some of the missing sprites include the Bathroom toilet and Maria from the Master Bedroom. Although the 'bed' is therefore accessible it does not 'activate' until all objects are collected.
 
Both tape and disk (.tap and .prg) file formats are included, each one contains the standard C16 version and the tape version also contains on its reverse 'side' the enhanced version for the Plus/4 however a separate file is available for that enhanced version, please see here for details as it is recommended to use the specific version for that variant if you wish to play the 'enhanced Plus/4' version.
 
A map (author: 'Csabo') is also included too of Willy's smaller mansion.

JetSet Willy for the Commodore Plus/4, written by Ian Davison and published by Tynesoft
 
This in effect an 'enhanced' update of the C16 version with approximately thirty-nine rooms instead of the C16's nineteen. That 'cut down' version can be found here
 
It too features the 'square stairs' as per the C64 version although they seem slightly easier to negotiate and it is easy to jump through them when appropriate. The choice of rooms included is generally quite sensible and the sprites and colour choices are a good match for the Spectrum/C64/Amstrad/BBC versions given the difference in platforms. There are very few in-game sound effects but the general 'feel' and play of the game is good.
 
Most of the interior rooms of Willy's mansion are present. The object placement reasonably matches the other main variants however there are more objects to collect given the fact there are less rooms.
 
There are no 'upper' screens beyond the Conservatory roof area although on the other side of the mansion the East Wall Base is present however there is no upper access beyond East Wall (so no Priest's Hole) and no Beach or West Bedroom.
 
The Banyan Tree, Wine Cellar and Tool Shed are present however there is no access beyond the right hand side of the Forgotten Abbey. To compensate for this the platforms in the Wine Cellar are slightly re-arranged to allow Willy to climb back out to escape, however an interesting "twist" on this is he cannot then simply jump out to the Back Stairway, the only escape is he must then negotiate the Tool Shed. Another interesting feature is there is no Swimming Pool although Orangery is present there is no downwards exit. The MegaTree is present too, complete with 'all branches'
 
Please see the screenshots for specifics, there is a screenshot of every room included.
 
The title screen is simply a mid-centred 'JET SET WILLY' line of text and a scrolling message which reads as follows:

As per the message it can be reasonably assumed this was 'built on' the C16 version even though as I understand it, it was released as a separate version. 

Enjoy!

Manic Miner for the Sinclair Spectrum.
 
The download includes the following 'officially released' versions:
[*]Bug Byte Ltd - The original first release [*]Software Projects - The 'later' original release [*]Ventamatic - Spanish language re-release [*]M.A.D - Mastertronic Added Dimension (Mastertronic

Manic Miner for the Dragon 32/64 range of machines.
 
Two tape files (.cas format) are included, the one badged as a 'Re-Release' is more compatible with other variants such as the Cole-Co.
 
The first release retains the keypad protection, the code card is included. The 'Re-Release' does not have this.
 
Cursor Left / Right = Left / Right
Shift or Space = Jump
 
P = Pause. Any other key while paused to resume
 
S = Sound On
Q = Sound Off
 
The Dragon version includes two extra screens not seen in other versions, these are "The Dragon Users Bonus" and "The End"
 
Similar to the Dragon version of JSW, there is a built in cheat mode...
 
 
 

Here's a jswmm special. :) A bug fixed edition of the original Spectrum version. The following changes were incorporated:
 
1. Black instead of blue initial loading page, the reason for this is (2) , it still retains the 'beeps' however they are played after the message not before.
 
2. New loading screen to replaced the 'loading' message present on the normal variants. It is compressed to save much time (down to 1485 bytes from 6912)
 
3. To further save loading time, the main code was also compressed (reduced from 32768 to 22459 bytes)
 
4. The decompress routine purposely returns to basic so it's easily savable as a standard 32768,32768 if desired. Also permits easy POKE entering too. Loader (used BlockEdit to display as it did not fit into one Spectrum screen) ignore odd spacing it looks fine in reality:
 
5. Built a ready-made Microdrive version and a +3 disk image as well. Identical to the tape version except a minor filename change for the disk due to +3DOS limitations.
 
6. The keypad entry was disabled as it seems superfluous these days.
 
7. Auto-pause has been disabled to prevent a lock-up when using an Interface 1. You can still pause the game via the usual keys but it will not 'auto pause' , also a patch was applied to prevent said lock-up if the user decides to pause the game for any reason.
 
8. The code that causes the in-game tune to deteriorate with each loss of life was disabled. Although intentional I've always considered it a bug in some way. I also noted (Thanks Skoolkid) that the length of each note slightly increases too with each life loss.
 
9. The otherwise invisible and unreachable object in the First Landing was given a form and simply moved down a few characters to enable it to be collected. This 'fix' replaces the official Software Projects fix of moving it to The Hall (where it would still be invisible) , this seems a better fix in some ways as the object is kept on the screen it was intended to be displayed on.
 
10. The official Software Projects 'fix' for The Banyan Tree was retained. This simply involves changing an earth cell to an air cell so the tree is climbable.
 
11. The official Software Projects 'fix' for The Attic was also retained with a minor alteration. The staring position of one arrow was altered slightly so that both arrows actually appear and function as was originally intended. Some 'fixes' for this it was noted remove one arrow completely.
 
12. The minor auto collect bug when Willy enters the Swimming Pool was fixed. There are a few ways of rectifying this however the simple method of simply changing the rope colour to cyan was used. The object form and placement remain unaltered where Matt placed it.
 
13. The 'double object' on The Beach was split into a single object and the 'extra' one was moved further down the beach into the 'waves'. The thought behind this is that way Willy is forced to use the conveyor to get that object.

14. The Conservatory Roof bug was fixed. The official Software Projects 'Fix' for this involves removing one fire cell so the object on the far right is just about reachable, however in practise is it almost impossible to collect them all without any life loss. After studying other variants of this screen, a different 'fix' was applied: The fire cells were moved into groups of two, followed by two objects, two more fire cells and finally two objects.
 
15. The issue where Willy can jump from the top of the Watch Tower (and ending up in The Off Licence as the 'Up' location is not defined) was fixed by simply shortening the ramp one block and moving the conveyor down one block. This fix is simple and it also means Willy cannot jump high enough to leave the screen via the top.
 
16. The concern where Willy can jump up from Dr Jones Will Never Believe This and end up hitting a fire cell in We Must Perform A Quirkafleeg was reduced by adding a fire cell to the top of the structure, making it very difficult for Willy to accidentally jump up and out of this screen in that manner and in addition the exit for 'up' from this screen was set to be the same screen so if Willy does manage to leave via the top, he will re-appear at the bottom of the screen.
 
17. The odd effect where Willy can jump through the top of Rescue Esmerelda and end up in The Ballroom was looked at. It's unclear if this was intentionally left in or an oversight however it did not make logical sense to allow Willy to 'teleport' in such a manner. The fix simply involves adding some earth cells to the top near the conveyor to prevent Willy from being able to exit the screen via jumping up. We gave some thought to using the empty room 47 here as The Belfry as per JSW2 but decided that would be an addition rather than a 'fix', something we wanted to avoid.

Enjoy!

We are pleased to release a mildly updated Spectrum version of Manic Miner.
 
1. The new loading screen I put together here has been used.
 
2. The code was again assembled using a 'real' speedlock loader for both its intended use (on a real machine) and for tape loading fanatics too. This is not intended as any form of 'protection' it is simply to cut down loading time from approx 3m15s to 2m30s. :) Only the game code is loaded rather than an emulator 'built' one as that would load all the memory which is not needed.
 
3. The game code was based on the Software Projects release rather than the more common Bug-Byte one, the reason for this was simply as the Software Projects release was later so it made more sense to base it on the 'last' code as such.
 
4. The 'typewriter' cheat was removed. The Software Projects version was "typewriter" instead of "6031769"
 
5. To make the game a bit more initially friendly, Willy starts with seven lives instead of three however:
 
6. There is no bonus life awarded every 10,000 points any more.
 
7. Minor detail: The scrolling message was slowed down a fraction so its more readable.
 
8. Minor detail: The scrolling message was altered very slightly to correct a few concerns:
 
 


 

In essence the changes are to capitalisation, spacing and the 'forgotten' pause keys.
 
Enjoy. :)

Jet Set Willy: The Nightmare Edition


 

Experience the timeless classic with a refreshing wave of new challenges and surprises! Solve the mysteries and find all the items... and be quick!
 
Jet Set Willy and Manic Miner Community (jswmm.co.uk) is proud to present a new, enhanced version of "Jet Set Willy".
 
The project was launched in the Contributor Lounge of jswmm.co.uk on 26th October 2015. The founding idea was to have a new JSW build, using the existing 48K engine, "with a few minor tweaks to platforms and the like". The plan was also to have 256 items to collect and to locate them in interesting places where Willy might not otherwise venture.
 
The project exploded in the following weeks, when several Contributors joined in and launched an avalanche of ideas and suggestions for the new build. By the time "The Nightmare Edition" was ready for release on 26th January 2016, over 2000 posts related to it had been published. More than 100 working builds of the game were created, as well as various minor revisions and numerous working files related to the loader and loading screens.
 
The general ethos of "The Nightmare Edition" was to work within Willy's original mansion, whilst maximising the difficulty of the classic rooms. However, a few extra screens have been added, inspired by the mythology surrounding the game. Another notable feature of "The Nightmare Edition" is that all unused graphics that were buried in the original JSW game engine since 1984 have been recycled and placed throughout the layout.
 
The name "Nightmare Edition" was adopted at some point along the way to reflect the increased difficulty of the game and the devious puzzles designed to make the player suffer. The game contains a substantial number of changes, including technical novelties such as different tunes in various areas of Willy's mansion, and a suitably nightmarish font style! Unlike in the original, the time limit is a serious factor.
 
The team of Contributors have worked hard together to convert their enthusiasm for "JSW" into a final product both enjoyable and challenging to the members of the wider ZX Spectrum community. The end result optimises the potential of Matthew Smith's original game layout, somehow managing to be both reassuringly familiar whilst at the same time fiendishly difficult - all within the 48K game engine!!
 
A detailed readme file of the building history, credits and technical changes is included in the package.
 
"Jet Set Willy: The Nightmare Edition" can be completed without losing a single life. The game has been play-tested extensively and is believed to be bug-free. However, if you find any problems, please report them to us at the community.
 
Enjoy... and suffer!
 
The download contains the following formats:
 
Standard .tap file, suitable for general use and transfer to other formats such as +3 disk or Sinclair Vega.
High speed .tzx file, suitable for transfer to use on a real machine. This tzx version must be loaded in 48K mode only.

A simple Basic program to allow convenient calculation of the starting position of Willy.
 
This is really more suited to games that offer multiple start positions as otherwise it is far simpler to move the position in JSWED or another editor. Games offering multi starts however this will assist as the default starting co-ordinates of one room may not be suitable for another.
 
It should be borne in mind this is a simple tool to assist rather than a 'solution' it simply makes working out a calculation a lot quicker than either calculating it yourself or inputting X and Y co-ordinates manually and looking at the result.
 
Although the calculations are provided in the excellent disassembly thus:
 

This is convenient if you know the exact "AT Y,X" spot otherwise it can become a bit annoying to re-run the calculation, especially if you accidentally mix up your X's and Y's. A simple input X,Y program would suffice however I felt the need for something a bit more friendly than "INPUT Y,X and display a result"
 
The 'Positioner' is intended to be very easy to use indeed. :) The program is reasonably well error trapped and you are not able to position him on the extremities of the screen which could cause potential issues.
 
Simply use the Q,A,O,P keys to move Willy to the correct location on the blank screen and the POKES (excluding the room #ID POKE which is 34795,#ID) are displayed in real time. This is a great boon as you can have JSWED open alongside to view the room layout to verify you have chosen the correct spot.
 
The file is a straightforward .tap , just load it into your emulator and away you go. There is no need (or point) in loading any game data, just load the positioner afresh.

A compilation disc for the BBC Micro combining:
 
Manic Miner
Jetset Willy
Jetset Willy 2 (both the 'cut down' and the 'full disc' versions)
 
Note that none of these have any cheats applied, I've merely combined four disc images from the stardot archive, renamed a couple of files (to avoid conflicts) and created a simple selection menu to build this compilation.
 
I hope you will enjoy it. :)
