I will chuck some figures around concerning the big chunk of data that is stored "the final barrier". When I was presented with that piece of data I wrote a simple piece of code and compressed it. The expansion code is small. The Final barrier data and the title screen data compressed into 170H bytes. The keyboard was stored separately, I think the keyboard compresses into 10 bytes. (the expansion code for the keyboard is not very big) It would be relatively easy to move the Final barrier graphics (compressed) , the boot, plinth and swordfish data into the unused source code space. The rest of that space could be used for code and un-compression routines. This then allows the room data to be compressed freely. Again it would be a simple task to write a routine to compress two sets of game data and place then into what is now the room data space. Yes a lot of work, but you end up with 40+ caverns, which would be two games merged. -------------------------------------------------------- Another reason I would not do this is not concerning the data, compression or data layout, it concerns how the game mechanics check for room numbers before altering how the cavern plays.

Curious to see the extent of room graphic data that is referenced by the game code, So I have done a quick scan through a listing. Not as many as I thought. These are the references to room specific data The Final Barrier Data Boot Graphic Data Plinth Graphic Data Swordfish Graphic Data (might be more, but not a significant amount of references)

Compressing caverns is very easy, however the game engine uses specific references to data within the room data. These references would all need changing JSW moves the room data into a specific area and the game engine then uses the fixed data positions. It would be possible to compress the data and modify the game engine to used fixed references (as per JSW) when playing a room, this permits the full usage of very aggressive compression on the room data. I would imagine 40+ rooms easily, (without looking at any data to quantify my statement) This is not something I plan on doing or want to do.

A long time has passed since the I wrote the above. I have been looking at ideas for a slightly different format, which would be inherently slower. So i investigated an idea and wrote the code to implement the idea. I eventually achieved a working game, and the code I tested and changed was from the above game. Worlds fastest was my claim at 10.61 seconds. The implementation of my idea in the game brings the above time down to. New game copy Method, 8.48 seconds. This is very, very, very fast: -------------------------- Whilst the method works on Jet Set Willy, I do not feel that it gives me enough scope to change the game into the format I had planned. Simply because speed was just one of the problems my new layout would present. The other is the amount of code that would need changing to implement the new layout. I had planned a big deviation in the basic screen shape, which ultimately modifies how every part of the game needs to handle the screen. Jsw is restricted by design to its present screen layout. The speed up code worked. Yet the multitude of changes needed to modify the screen are extensive, and in most of the cases that I have looked at the relevant code is not easy to change. -------------------------------------------- Double room walk down from 20 seconds to 8.48. with a lot of extra code. (but still 128 rooms and only 48k) .

JSW 128 VL5 View File JSW 128 VL5 This was written just after JSW 128 VK3. It is an extension of the game, which I pushed towards the feel of Manic Miner In this version changed over a period of two weeks, I took the idea of game save status and changed the way JET SET WILLY plays. If you can play JET SET WILLY then this version might actually be a hindrance to you. For the lesser player it adds the ability to keep on trying a sequence of the game until they master it. The only constraint to finishing is the time limit. There are no lives to be decimated, you are totally free to roam, and free to try any action. The catch is simply that for every instance that you would normally die and loose a life you transported back to the last portal that you visited. Infinite lives and lots of time, sounds easy to finish? The double catch is that every time you die the game re-installs all the objects collected since the last portal, it also resets the ammo. This makes collecting objects different from when you play with infinite lives, a death jump or leap to collect an object, will not collect the object but will transport you back to the last portal, which might be some distance away. You have to perfect all the paths that collect objects and manage to get to a portal and save them. It also changes the way willy re-appears back in a room after death. In this version that simply does not happen, he is moved back to the last portal. f you don't visit the portals then a death could take you back many many rooms and many, many objects collected. Those portals are the most important place to visit. If the game was easy in the standard format, then this version will not have any change in how you play, its design is for the casual player to permit wandering without real consequence. One technical change from JSW128 VK3 was that is Willy does not change colour when immune. This was changed to the room name changes colour when immune instead. This small change was to enable willy to jump on ropes when immune. It has an inbuilt cheat mode, which uses a different cheat code from all other versions. --------------------------------------------------------------------------------------------------------------------------------- In this demo version I have pushed previous attempts at upping the games speed into oblivion. The Title of the file is JSW VL5 demo.tap. Which has a lot more graphics than JSW 128 VL5.tap It does however display the fact it is a demo version.

Updated to the 3rd method. (with the other 2) Was not happy with the speed. So decided to use stack copy with a sprite screen save routine. E.g. The sprite draws on the screen and at the same time saves the background it writes to. Doing this removes one of the long and slow stack copy routines. 100% this is easily fast enough to do perils of willy.

wrote a stack copy version and wondered why it was so slow. Checked the code, and noticed I was redrawing everything on every loop. (it was a test file) With the stack copy the game is viable in this format.

Interested in how this would look if written in the manor I would write it. File included. written over three hours. I have no intention of writing this game, and was more interested in the speed aspect of adding a big chunk of extra screen. Possible to increase speed with stack copy. Perhaps I should alter this code to see what a stack copy would do. The screen mapping is the same height as perils and the width would be mapped as 1.5 blocks per original block. Would still need platforms jiggling about. Again I will state I have no interest in writing this. 1st file "pow.tap" uses LDI 2nd file "Pow Stack 2.tap" uses Stack copy - can move left right. 3rd file "Power.tap" uses a block save and stack copy pow.tap pow STACK 2.tap power.tap

The spectrum playing area and hence the editing area of jsw on the spectrum is 32 tiles wide by 16 tiles high, The perils of willy uses the Vic 20 screen which is 22 tiles wide and 23 tiles high. (this can be changed). Just the fact that the vic 20 game perils of willy has more than 16 tiles in height makes a conversion to the spectrum a non event using the existing clones of jsw on the spectrum. I am ignoring the tile aspect ratio, and the problems with the width. If the screens are remapped to use only 16 tiles in height, then it is not a rewrite onto the spectrum, but a re-design based on the Perils of Willy, which is not the same. The Perils of Willy has a set of known bugs that are used to progress in the later levels. These bugs might be present in JSW on the spectrum, but if they are not then a copy has to remap the screen and change the movement of the game, and hope that it bears resemblance to the original. Easier to start again- how about using PGD?

Taking heed of advice (post 20) the two files (post 19 ) have been zipped into a folder. The original problem was the forums interface will not permit the uploading of executable files e.g. .exe and .com To overcome that problem I renamed the two files and uploaded them .TAP with the explanation for the need to rename back to .exe files. However post 20 pointed out that this forums interface will permit Zipped files, which removes the problem associated with .exe and .com files Since that is a neater and quicker solution for others, the files that needed renaming along with the text explaining the need to rename the files (in post 19) has been deleted. In their place is one single zipped file.

I will upload two versions of this program. Please take notice of my comments. Since this has only ever run on my machine, and I can not be expected to stretch my knowledge to unknown and untried machines. I recommend the host directory to be close to the root directory. e.g. the directory c:\games\jsw\test should prove no problem The directory c:\game\versions\test\root\jetset\modified\deep\problems\test\ might have problems Version 1. TRY THIS VERSION FIRST. File:- No_Otput.exe The reason I say try this version first, is because it has no output file. and apart from opening files to read has little impact on the host machine. The purpose of this file is to identify that the other version has an environment that it should be happy with. If this version runs with garbled output, can not find the files, or has opened the wrong directory. Then DON'T RUN the other file, because it will create a file called "Zxxx9876.txt" somewhere on your drive... version 2 File:- My_dir2.exe The same program as above, with the ability to output the text into file "Zxxx9876.txt". This is opened in the directory of the files it lists. ----------------------------------- common to both versions (unless stated otherwise) Two lines top left, brief list of keys (My_dir2.exe will have an extra option s=save) The direction keys duplicate the keys "Q","A","N","M" lowest line on the left is the dos path that is used for the save file and the files opened The next to bottom line on the left is just confirming the name of the text output file "Zxxx9876.txt" The lines in between (on the left) will show the file names found in the current directory (if any) key "Q" move up a file key "A" move down a file key "N" move back a room name (if names are displayed) key "M" move forward a room name (if names are displayed) The current file name will be highlighted when moving up and down the file name list No idea what will happen if the room names are scrolled into silly positions. e.g. room number 300 or room number -150. Key "S" only in "My_dir2.exe" . this will save the list of room names, up to 64 (might need the text file to be edited at a later date to remove junk names) The saved files are added to the end of the file. If "s" is repeatedly pressed it will just keep on adding the room name list. It is up to the user to decide what if any files are to be added to the file name list ----------------------------------- And something not mentioned anywhere else. The files are PC executable files, and will not run on any other machine. Taking heed of the advice on using a zip file. the two files are in the zip folder And finally if these prove to be useless, I will delete the files.... My_dir2.zip

I wrote a small program in Qbasic7. Which showed up some problems (for me). Multi load TAP files could/can have the data anywhere, no idea where to look. Compressed files are Compressed and need expanding before searching for data Both the multi load and compressed tap files, can have their data extracted by running and saving the game as a memory dump. Even if the dump will not run it is good enough for the room listing program to examine and find the rooms. 128k files are not considered in any form outside the original 48k memory dump. Qbasic7 has basically no real DOS interface--- (windows is a foreign entity) and disc searching is not on the cards. The routine I wrote is very, very, very restricted in usage. It does not traverse directories, it assumes and only uses the directory that is current. The strange thing with the current directory is that I can run a program that permits the usage of directories and allow me to run programs from them. BUT when my QBASIC derived program is run,it is still using the default directory as set by the system, and not the directory from where it was run from. The output file generated is sequentially added to, and the assumption made is it does not already exist. (if it does it will add text data to the end ) And the last big hurdle was QBASIC7 (as used by me) still lists file names under the old dos system. e.g. [filename.ext] , none of the long extended file name syntax such as "JSW the continuing adventures in 23 parts" ------------------------------- What the routine I wrote did. It reads the current directory in dos format and displays the file names in a big long list (in dos format) A cursor can be moved up and down the list and it scrolls if necessary. The current highlighted file is searched for some data that should be in the code (if it isn,t then it is assumed it is not a JSW FILE) when the data is found it then adds a known offset and lists what should be the room names. These are displayed on the right of the screen and can be scrolled up and down. If the data looks like a jsw file, then it can be saved with the dos file name. It is added onto the end of the text file. the output is similar to the data I dumped above. NOTE it searches every file in the current directory.... I just plonked a selection of JSW files in one directory, added the search program file into that directory, and then ran the search program from that directory. The text output file is generated into the same directory. ---------------------------- The basic (no pun intended) routine is simple, but this needs to be done with a language that permits windows and directory traversing. Whilst the routine I wrote is a routine that could have existed 30 plus years ago in DOS

The Date I used 1985, was obtained from a history of Tandy site which listed their computer model history. I feel it is wrong, and I will change the date accordingly. Manic Miner released August 83 by Bug Byte and later that year by Software Projects Jet set willy released 1984. The megatree and the period after the release of Jet Set Willy are roughly the same. E.g. After the release of Jet Set Willy and around the end dates for the release of Jet Set Willy II. Which put the dates back to very vague. (TRS stands for Tandy Radio shack) which is why I will call the computer a Tandy when it has a radio shack label From another site listing the history of Tandy computers we get TRS-80 Microcomputer System Model 1 Level 1 Radio Shack - Tandy 1977 TRS-80 Color Computer Tandy 1980 TRS-80 Model 100 Portable Computer Tandy Radio Shack 1983 <<<<<<<<<<<<<<< Tandy 102 Portable Computer Tandy Radio Shack 1983 TRS-80 Colour Computer 2 Radio Shack Tandy 1983 Tandy TRS-80 Model IV Tandy 1983 TRS-80 Model 102 Portable Computer Tandy Radio Shack 1983 Tandy Color Computer 3 (CoCo 3) Tandy 30th July 1986 Tandy 1000 HX Personal Computer Tandy 1987 Tandy 1100FD Laptop Computer Tandy Radio Shack November 1989 Which is unfortunately no help. It simply dates the model 100 back as early as Manic Miner . e.g.83 Perhaps the other site I read the date from was confused by the model 100's name, which was originally the Kyotronic 85, which sold in Japan. As is usual I can not find the site in question (browser history will be in the 1000's, So I am not going through that) The gist of the original dialogue was that the tandy model 100, was named the Kyotronic and designed and built in Japan. It did not sell very well and was eventually bought by Tandy and repackaged as the Model 100, sold in America in 84, and brought to the UK for 85. Wiki does not agree with that timeline and the model history of Tandy (as listed above) also does not agree. So I am editing the dates listed with the pictures.

The most common file/picture of Matthew is this and a series of pictures taken at the same time. Either that or this was his favourite worn to bits jumper. A couple of clues on the dating of this picture and therefore all the pictures taken at the same time. The monitor is sat on a Tandy hard drive. Bought with the proceeds of Manic Miner The portable computer he is sat behind is a Tandy model 100, This was sold originally under a different name, but became the model 100 for Tandy in 1985. (see post number 15 concerning this date) The third picture is taken at a residence in Birkenhead, after the completion of Jet set Willy. This was the time which achieved very little and is I supposed classed as "writing the megatree" Addendum, due to having re-assigned the date for the model 100 as early as 1983 (possibly). The only definite clue for the date is the hard drive. Which is after Manic Miner.

Decided to use better maps to place the building better on the ground. The crude overlay, was just that very crude. This places the building more accurately on the ground

I walk into the "banyan tree" room, slow it down to the slowest setting and then can pass through the room nearly every time, at the first attempt. Something I can not manage when I play the original. I will time the slow speed. ----- It is timed at 25.93 . So the slow setting is around 25%+ slower than the original.... so a 25%+ reduction in speed makes it so much easier. And a doubling in speed makes the traversing a lot faster.

I made a statement "WORLD'S FASTEST" in one of the screens on JSW128 VK So here I will justify the claim, and add some data. The Timing quoted for all versions is the time taken to do the same double room walk. The double room walk, is the walk through "The Kitchen" and then through "West of kitchen" Times are displayed to 100th of a second. Whilst the timing is accurate, my reactions varied a lot. Since music only slows this down, all times are without music. The T-states quoted are the times needed to copy one byte from memory and move it elsewhere. This timing is needed because the slowest part of the game is the huge amount of data copied on each and every game loop. It is these copies which have one of the largest influences on how fast the game runs. (an edit to revise and hopefully lay out this data in a clearer manner revision done 21st October 2024) Matthews unmolested code using LDIR - each byte taking 21 T-states - manual timing to do the Double room walk - 19.96 to 20.12 rounded up to 20.00 seconds. LDIR 21T-states - WALK 20 seconds My code changed back to using ldir's is comparable in time, which considering all the extra routines, is to be expected. - 20 seconds LDIR 21T_states - WALK 20 seconds My code using a long line of LDI's ---- each byte taking 16 T-states plus a small overhead - 15.46 seconds. LDI 16 T-states - WALK 15.46 seconds Mark Woodmass posted a "marginally faster" versions of Manic Miner and Jet Set Willy to alt.binaries.comp.sinclair on 27th January 2002 - his version of jsw does the double room walk in 15.51 seconds. Mark Woodmass uses a stack copy routine and it also destroys the rope routine. (e.g. it is bugged) STACK COPY 10.5T-states - WALK 15.51 seconds Mysterion posted his Turbo versions, so I will list the times from his versions. These use a stack copy method and the 128k, increase in speed is achieved by rolling the code out further. Matthews code using Mysterion Stack copy --- stack copy has a theoretical minimum of 10.5 T-states, but the overhead is quite high two sets of timing - 13.71SEC IN TURBO JSW IN 48K and 12.14SEC IN TURBO JSW IN 128K STACK COPY 10.5T-states - WALK 12.14 seconds in 48K STACK COPY 10.5T-states - WALK 12.14 seconds in 128K My code . These are the speed of my stack copy routines - STACK COPY 10.5T_states - WALK 10.61 in 48k This is 3.1 seconds faster than Mysterion's version in 48k My version in 48k is still 1.43seconds faster than Mysterion's version which is rolled out and will waste quite a large chunk of the 128k of ram needed. So yes "WORLD'S FASTEST" (At the time) NOTE the timing depends on the individuals response to the change of screen and partially to the machine it is being tested on. The times I list are consistent with the machine and hardware I use. (others will obtain different timing) however the overall trend will still be as above. Addendum concerning Speed and T-States From the above it is easy to see the relationship between the double room walk time and the T-State's for the method used to do the screen copying. LDIR 21 T-states 20 seconds LDI 16 T-states 15.46 seconds STACK COPY 10.5 T-states 10.61 seconds

Something that I posted back in August 2016 on Facebook drawing By D.P.Rowson. And with his comments Mock up. Not to scale and drawn on recollection only, of the building above. Top picture is an enlarged portion of the lower picture. Room allocation was dynamic, so this allocation is a snap shot.

Software Projects occupied the part I have shaded in purple.

Very few pictures exist of the bear brand Picture 1 down the side of the main building Picture 2 view from the air Picture 3 Gate past the main office down towards the works Picture 4 A crude overlay of the building on a map. Pictures 1 and 3 by John Shaw. Just before the demolition. All the workers used the nearby Sainburys , as a food source.

1) Differing Versions -- The game cycles every main (Title) screen display, between Bug Bytes and Software Projects version. The animated display on the main (Title) screen (near the house) shows the sprite from the version that will play. There is no option to switch mid game. ***NOTE*** the differing versions are swapped on the Title screen, If a version is displayed and you want the other version. Then start the game, and the abort back to the Title screen. The versions will have been swapped. 2) Toolkit -- The toolkit will rebuild collapsing floors when active. When the toolkit icon is displayed pressing "9" will rebuild all collapsed floors. Needed when you have collapsed all the floors and have no way of returning. Pressing "9" rebuilds the floors to enable escape. This is mainly needed when the medical kit is used and he has managed to get stuck somewhere. 3) Alternate movement -- In manic miner to jump and turn around at the same time requires Willy to do a standing jump. e.g. the sequence from jumping right and holding down the jump key and then trying to turn around. Normal Manic miner movement - Jump right - static vertical jump - jump left. The alternate style of movement removes the static jump. Willy will do the sequence of - jump right - jump left (no static jump) This also happens when walking and turning around. the difference between the two is one frame of movement. The alternate version enables willy to turn around faster. This change was introduced to enable faster movement response. It is subtle but if you are aware of the change it enables faster response when turning, which can be the difference between life and death. Easter egg- When the credits screen is displayed. Hold down "1" and tap enter.
