#855 Willy in 3D

Posted by ZedEighty on 22 November 2015 - 12:28 PM

Hallo Everyone! 


I was directed here by Stuart Brady on the Spectrum 4 Ever Facebook group. I've been dabbling with 3D printed models and have designed a few based on characters from Matthew Smiths' classics. After I posted some pics on FB Stuart suggested that you folks here may also like to see what I've made:












The models are printed in laser-sintered nylon, and are about 4 cm tall. The non-white model parts have been dyed. I designed the 3D models myself, and had them printed by Shapeways.

#6997 A total rewrite of JSW in 48k using Matthews core code

Posted by Norman Sword on 07 September 2017 - 02:21 PM

I have resurrected this file By Derrick.P.Rowson. Which was on a crashed hard drive. 


This is Not finished, and never will be due to a catastrophic failure of the hard drive.

This is a few weeks work and alas there was no backup of the program.


This version does not have any of the new logic playing sprites.

E.g. sprites that followed willy around both vertically and horizontally, and were free roaming around the screen.

The logic had enough sense to move the sprite wherever it needed.



This version was a development towards having the full Manic Miner + Jet Set Willy in 48k




This game has inbuilt options. (password protected)

#6988 Manic Miner by Software Projects + BUG-BYTE

Posted by Norman Sword on 06 September 2017 - 02:52 PM

This is a modified version of Matthews Manic Miner. The core code has been edited extensively.


All data was left intact from #b000 onwards, but is modified at run time to swap between the Bug-byte version and the Software projects version of Manic Miner.


The list of changes is very long. Most of these changes are not evident, some are very evident.




1) change the style of jumping and movement


after cheat invoke


4)  Immortality

3)  Platform rebuild - when invoked the "9" key rebuilds the platforms


Holding down the "9" key and pressing

1) move back a cavern 

2) move forward a cavern

#5402 JSW As Manufacturer (probably) intended .. kind of...

Posted by IRF on 10 December 2016 - 12:06 AM

Looks good!


Regarding moving Esmerelda, that shouldn't pose any problems in this specific case, as it's the only instance of a guardian of the same class in the game.  :)


However, in general, if you're changing the parameters of guardians then you have to be careful as it can affect other guardians of the same class elsewhere within the mansion.  :ph34r:

#5299 The AND instruction

Posted by SkoolKid on 12 November 2016 - 03:01 PM

Is there any good reason (e.g. in terms of the effect on the Flags, perhaps?) why the original game engine uses an XOR command at #91FB, instead of an OR?


It's the instruction which merges a guardian's INK colour and BRIGHT value (Bits 0-2 and 6) with the PAPER colour (Bits 3-5) of its host cells.

No, there's particular reason to use XOR instead of OR here. As you've noted, there's no difference in the resulting value in the A register, and there's also no difference in the effect on the flags (which are not checked anyway).

#5007 Atari ST ( JSW )

Posted by SedricAndCharlie on 14 August 2016 - 10:22 AM

I wonder at what point Software Projects changed their mind and commissioned the Stephen McMaster MM/JSW games for the Amiga? Also this led me to reading about Boing! on the C64, the rejected Chris Lancaster conversion of JSW that was passed onto Bubble Bus Software and reworked to avoid copyright. Seems like Software Projects had a lot of odd stuff happening behind the scenes

#4947 Free space and code optimisation in "JSW"

Posted by IRF on 04 August 2016 - 10:35 AM

I'm probably missing the point here but why not just compress the entire code? I know people here are not a big fan of compression as it makes the code harder to read like with JSW2 for example but is that not because there is no decompressor available making editing a lot harder?

but what if you was the one doing all the compressing? might it be easier to edit the code then compress and decompress at will .. imagine the extra rooms and nasties you could cram in using the original JSW engine...

just a thought that's all

I suppose that's one option.

However, I've considered it a nice challenge to find 'efficiencies' in the existing code and therefore try and pack as much into the available space as possible, without compression.

And if nothing else, taking on the task has helped me get my head around how the Z80 machine code works. (I was clueless just a few months ago!!) :wacko:

#4751 JSW and MM Editors for other platforms

Posted by SedricAndCharlie on 02 July 2016 - 05:18 PM

I always wanted an editor either for the C64 version of JSWII (which for me was Jet Set Willy, as it was the one I grew up with) or for the Amiga version (which was the version I consoled myself with long after our C64 had died inside). To my knowledge neither exists, however

#4706 Free space and code optimisation in "JSW"

Posted by JohnElliott on 20 June 2016 - 06:41 PM

However, I've just had a look in JSWED, in the Game tab, and it looks like both of these boxes (as well as *all* of the other ones *except* for "Black Willy") *cannot* be either ticked or unticked - they are filled with blue, sort of. I'm not quite sure how to interpret this...


It means that at least one byte in a location touched by the patch is neither the original one from JSW, nor the modified one from the patch. So JSWED cannot safely apply or deapply the patch.

#4654 Complete List of bugs, quirks and anomalies

Posted by IRF on 13 June 2016 - 09:39 PM

Willy enters the 'toilet dash' as soon as he reaches the foot of the bed, regardless of whether he walks or jumps to reach that point.

His getting stuck on the bed is caused by the bed's Conveyor action 'cancelling out' Willy's automatic urge to run rightwards (there's an XOR command involved).  The fact that the 'P' key doesn't release him from this predicament is probably a 'bug' (although Danny might disagree!).

I guess the pillow is a Fire cell because there were no other cell types available when Matt Smith designed the room!

#4605 Complete List of bugs, quirks and anomalies

Posted by Metalmickey on 08 June 2016 - 12:15 AM

Firstly, apologies if a similar topic like this has already been created elsewhere feel free to delete it if there is a better one, i did have a look around and couldn't really find anything like it so i thought i'd create a thread where everyone can contribute to the list of all known oddities found in the game.


Secondly this is not a request for help in working around these bugs, more really a point of reference and maybe a source of information for newcomers and those who didn't play the game so much and don't already know about them all and one single place where they can be looked up


I thought i might start with the most obvious and well documented ones the first four of which prevent the game from being completed:


'The Attic' - The most famous and destructive of them all which of course is triggered when Willy ventures into the attic. A rogue arrow causes all manner of destruction around his house and ultimately renders the game unplayable.


'Conservatory Roof' which features the booby-trapped item, or maybe it's just a little too closely guarded by a 'fire-cell' 


'The Banyan Tree' with what looks like an out of place earth-cell right of the trunk meaning that Willy cannot make his way upwards to the Bit Of Tree above


'First Landing' with the phantom object which is neither seen nor collectible.


The rest of these are comparatively harmless or can be avoided

such as...


'The Nightmare Room' featuring the ugly green blob which, when i first encountered it i thought it was a fire-cell and so i spent many a long afternoon trying to work out how to collect the object without hitting it... turns out that it was just a conveyor belt ... who knew?


'Cuckoo's Nest' with the somewhat disorientated saw that doesn't change direction when it comes back the other way


'Under The Roof' with the phantom 'fire-cells' that prevent Willy from dropping out of the bottom of the screen to the right of the tree trunk, interestingly enough this one was even left in the 'Nightmare Edition' ... maybe Mr Smith deliberately left it there... who knows?


'The Beach' and 'The Roof' both feature a rope that Willy can jump from and reappear at the bottom of the screen


'Rescue Esmeralda' has, in all probability, an unintentional secret passage to 'Ballroom East' when jumping from the conveyor belt at the top right of the screen


'The Watchtower' also has one which takes Willy all the way to the 'Off Licence'


'The Swimming Pool' has an object which Willy needs to make no effort whatsoever to collect, he merely needs to enter the room and it's his


'The Orangery' Here Willy has been endowed with a magnetic head when jumping up and hitting the ledge from the stairs at the bottom left of the screen - not so much a bug, more of a quirk

Apparently i never knew this but there is also a bug which means that the conveyors in rooms such as the West of Kitchen and Tool Shed are not drawn properly .. and the one in the Wine Cellar is not supposed to be there at all.


Finally there's that 'halo' effect where a nasty as a 'bright' blue background following it around, this is evident in 'I'm sure I've Seen This Before', the Emergency Generator and On A Branch Over The Drive


There's probably a few that i have missed, feel free to contribute!

#3557 'Guardian Aura' Bug Fix and miscellaneous other patches

Posted by IRF on 02 April 2016 - 12:30 PM

Further Update: I have also fixed the problem described here:



Update: for an optimised solution, see this post on page 3 of this thread:



Here is a patch for the bug that is seen in Jet Set Willy in non-Black rooms, if a Guardian is present that has a different Brightness setting to the Air cells in that room. e.g. The Flying Pig in Emergency Generator.

The following 'new' code should be added - I suggest you locate it between #96f4 and #970b:

7e e6 38 c2 f1 91 dd 7e 01 e6 0f c6 38 e6 47 4f 7e e6 38 a9 4f c3 fd 91

Then the existing code at #91ee to #91fc should be edited as follows (this is based on the suggested starting address for the new code listed above):

c3 f4 96 dd 7e 01 e6 07 4f 7e e6 78 a9 4f 00

(The last byte is a NOPped out spare byte in the guardian-drawing routine.)

The above patch is an amalgamation of two routines in the original Jet Set Willy code (one of which was previously unused, except in Manic Miner). It eliminates the 'Guardian Halo/Shadow' bug in non-Black rooms, whilst allowing a wider range of guardian colours (Bright and non-Bright) in rooms with Black screens).

N.B. There is a simpler fix for the Guardian Halo/Shadow Bug that uses fewer bytes, but it would limit the colour palette of guardians throughout the game. i.e. with the simpler fix in place, all guardians on a given screen must be either Bright or non-Bright - even on Black screens where the Guardian Halo/Shadow Bug doesn't manifest itself. So for example, you would no longer see a Bright Red AND a non-Bright Red Monk in The Forgotten Abbey.

Note also that the way the alternative guardian-drawing routine (a remnant from the Manic Miner code) is implemented, avoids the following bug from occurring:


So the above fix really provides the 'best of both worlds'!

#3137 Pokes for Fixing the Cell Graphics Bug in JSW

Posted by IRF on 25 February 2016 - 11:51 AM

I thought it would be good to have a standalone topic for easy reference, containing the Pokes in Hex (EDIT: and in Decimal) that fix the Cell Graphics Bug.  The credit for most of these goes to Stuart Brady (AKA Zub), although I had a bit of input into fixing the ramp/conveyor pixel patterns and conveyor attribute byte in The Nightmare Room.


I'm not sure if this should be in the 'Remakes' section of the forum or elsewhere; I can relocated it if necessary.  However, I thought this might be the best place as it is highly advisable for anyone developing a game/remake using the JSW game engine to apply these Pokes, to prevent their intended cell graphics from being corrupted in an erratic manner!


The Cell Graphics Bug fix (a generic patch to the game engine) is achieved using the following sixteen Pokes:


POKE 8d54, 06

POKE 8d55, 06

POKE 8d56, cd

POKE 8d57, bb

POKE 8d58, 93

POKE 8d59, 59


POKE 93bb, 11

POKE 93bc, 08

POKE 93bd, 00

POKE 93be, be

POKE 93bf, 23

POKE 93c0, c8

POKE 93c1, 19

POKE 93c2, 10

POKE 93c3, fa

POKE 93c4, c9


EDIT: The above, in decimal:


POKE 36180, 6

POKE 36181, 6

POKE 36182, 205

POKE 36183, 187

POKE 36184, 147

POKE 36185, 89


POKE 37819, 17

POKE 37820, 8

POKE 37821, 0

POKE 37822, 190

POKE 37823, 35

POKE 37824, 200

POKE 37825, 25

POKE 37826, 16

POKE 37827, 250

POKE 37828, 201


An additional fix, specific to The Nightmare Room (where we believe Matthew Smith's intended attribute byte for the conveyor was misplaced in the code, as the bottom pixel row of the ramp cells; this had a knock-on effect on the colour scheme and pixel pattern of the conveyor, even with the Cell Graphics Bug fix in place), can be achieved using the following five Pokes:


POKE ddcc, ff

POKE ddcd, 02

POKE ddce, a5

POKE ddcf, ff

POKE ddd0, 5a


EDIT: The above, in decimal:


POKE 56780, 255

POKE 56781, 2

POKE 56782, 165

POKE 56783, 255

POKE 56784, 90

Welcome! :)


This site is not intended to take any traffic away from other existing sites, its simply a place we have to discuss the range of JetSet Willy and Manic Miner games. Its fair to say these games have stood the test of time very well even now.


Although primarily aimed at the Spectrum versions, we welcome any contributions and thoughts on other platform variants of these games too, both standard and edited.


Feedback (both good and bad!) and suggestions are always appreciated, simply start a new topic in this area (News/Feedback) if you have any comments to provide.


Thank you!

#11567 Hello!

Gosh, it's humbling to know that I hava


Hi Geoff, and welcome! We've used your 'Patch Vector' concept in several games that we've released here at JSWMM!



Welcome, Geoff! :) It's great that you have joined this community!  :D


Thank you for wonderful contributions to the scene! They are greatly appreciated and have been a basis for further development of JSW games  :thumbsup: .


I am not sure how much you have been following the MM/JSW scene over the years, but - as Ian mentioned - your 'Patch Vector' concept has been used in various projects in the last four years, both in the form of your original PVs and numerous new ones.


Your documentation describing your PVs has been instrumental in this development - thank you for it as well!  :thumbsup:


From my personal perspective, the Special Edition of "Willy's New Mansion" is a project I would like you to know about and have a look at, if possible. It features a number of your PVs applied in various rooms, plus a number of new PVs developed especially for it. Due credit is given to you amply in the Readme, where there are also disassemblies of all of the PVs used, both the ones you designed (their disassemblies were created thanks to your documentation) and of the new ones. I know you once had a look at the Original Edition of "Willy's New Mansion" back in November 2004 (you told me that in an e-mail) - if you ever have a go at "WNM" SE it will be a whole new experience! I wonder if you would recognise your own PVs there... :)


Is it possible you will take up any JSW projects again? Shall we ever see the release of "Willy and the round tuits" or "Willy does the Great Pyramid"?  ;) 

How humbling! It's good to know I have a legacy of sorts :-)


A potted history of what I've been up to since ZXWtBS: I started work on the Great Pyramid some time in 2004, but this ground to a halt before long and has been in creative limbo ever since. Every so often I think about reactivating it, but I have other Real Life things to worry about. I might, but I can't promise anything. I've also thought about further changes to Geoff Mode, but again, I need some round tuits.


I haven't really kept in touch with the MM/JSW scene since then, aside from occasional searches for my JSW games to see if anyone's said anything nice about them:-) I was deeply touched to find ZXWtBS on the list of "Best JSW mods" at the Manchester Expo, and that ultimately led to me joining up here.


I'll have a look at WNM when a convenient time presents itself; it sounds interesting!

#11559 Hello!

Posted by geoff on 01 February 2020 - 11:11 AM

I don't know if this is the right place to put this, but never mind. I'm the author of, among other things, "Willy Takes a Trip" and "ZX Willy the Bug Slayer", and I've come to join this community. Hello to you all!


Note: For various complicated reasons, it'd be good if you don't mention my surname here.

#11394 JSW's 35th birthday party at Manchester PLAY Expo

Posted by Richard Hallas on 24 October 2019 - 08:25 PM

I've just belatedly noticed this thread, so as one of the people who was there, I thought I'd say a few things from my own perspective, particularly about the competition.

Danny is correct that my "Join the Jet-Set!" came second in the competition, after "Maria vs Some Bastards".

As for the competition itself, I had very mixed feelings about it. On the one hand, I was pleased to have one of my games picked at all; that in itself was a real honour, considering the sheer number of JSW games developed, and also considering that mine is one of the very oldest, having been completed back in 1985.

But on the other hand, the way the competition was presented and run was simply not fair on any level. What was the criterion on which the games were supposed to be judged? How they played? How they looked? How much they stretched the JSW engine in terms of quirky exploits or new routines etc.? Having a competition for which one is "best" is actually pretty meaningless. The only criterion that the audience was permitted to judge, really, was how the games looked – based on the 30-second visual run-through that each one got.

That's the most superficial way possible of judging the games, and even then it wasn't a fair comparison because we weren't comparing 'like with like'. Of the five games being judged, four were pretty straightforward JSW games that looked much like the original JSW and played in the same way. But the fifth, Maria vs Some Bastards, is much the most recent of the set and has been MASSIVELY hacked about to allow the game engine to do all kinds of things it was never supposed to do. The end result is that it has big, bold, spectacular graphics that none of the other games could achieve, and it totally outclasses the competition in terms of looks. But no-one can actually do what that game does with the game engine without a massive amount of hacking; you can't achieve those graphics just by creating a new JSW game with an editor.

So, the audience was asked to judge which of the new games appeared to be the best, based on a brief, superficial viewing of a few screens, yet what they were shown was four 'normal' JSW clones and one super-enhanced on that featured a massively rewritten engine that permitted all sorts of big, bold, cartoony graphics to be used. So *obviously* Maria vs Some Bastards won; there was really no other possible outcome, under the circumstances. Maria vs Some Bastards was written 18 years after Join the Jet-Set! was released, so it's hardly surprising that there'd been plenty of time in those 18 years to do a lot of hacking and find ways to make it look better! Is it really fair to compare a game that's barely been hacked at all (in terms of its engine) with one written two decades later and hacked massively?

I'm not being a sore loser, honestly! I'm just pointing out that it wasn't a fair competition. None of the other four games stood a chance. It was also unfair that the presenter, as he ran through the five candidates, made sure the audience knew which was his own favourite in the set (it was neither mine nor the actual winner, so at least it didn't influence the audience too much).

I don't begrudge Maria vs Some Bastards winning in terms of the effort that's gone into creating it, because it's actually a pretty remarkable game and a lot of work and talent has gone into its creation. I just didn't think it was fair to put that particular game alongside other 'normal' JSW games that didn't stand a chance because they hadn't been totally rewritten in the same way. Besides, if the games could actually have been judged in terms of how successful they are *as games* (i.e. in terms of being fun to play), then I think my own game might even have won. The point is that I deliberately designed it to ( a ) recapture some of the whimsical humour of the original, ( b ) be fun to play, ( c ) be interesting and fairly easy to explore, and ( d ) above all, to be fair. The latter point means that (i) active steps were taken in the design to avoid death loops, (ii) there are few nasty traps (there are a couple, but it's easy to learn where they are and avoid them), and (iii) the game can be completed without losing even a single life if you're skilful. I've always believed in fairness, and my game is fair and completable. That puts it in stark contrast with most (all?) of the other entries, which range from weird and unpredictable to impossible to complete. Maria vs Some Bastards is impossible to complete without a third party hack (released in the same week as this competition!).

On a positive note, I was given the microphone and was allowed to talk through my own game as it was demonstrated on the screen, which was nice. That permitted me to mention a couple of important points about it, namely ( a ) it was one of the very first new JSW games that demonstrated that it was possible to recapture something of the spirit of the original in a new setting, and thus played a significant part in kickstarting the surge of enthusiasm for creating new JSW games, which arose after my two games and Adam Britton's three had been released in the 1990s; and ( b ) I was the first person to figure out how to reprogram the in-game music and offer new tunes in my games.

Looking back at my own game, and having played it again recently because of this competition, I can see various ways in which I could have made a better job of it, and there are certain things I wish I'd done. E.g. I should have been less half-hearted about redesigning Matthew Smith's guardian graphics and drawn more of my own original creations; and I should have animated some of them better and not made them so 'jumpy'. Maybe I should have redesigned more room graphics too (i.e. walls, floors etc.). And so on. Considering all the other games that have come since, and all the engine enhancements, it's shown me just how ingenious some people can be with this game and made me feel that maybe I cut a few corners that I shouldn't have done. But to be fair to myself, I was only a 15-year-old schoolboy when I wrote it (amazing how some of those memories are still quite fresh, 35 years later…!), and I had lots of other commitments at the time, and very little free time of my own… so actually, I do think I managed to make it a pretty good game under the circumstances. Anyway, it was good enough to inspire others to make many more games of their own, so I'm pleased about that, and if I was indeed partially responsible (through my two games) for helping to kickstart the JSW revival then I'm delighted about that. In the end, whilst I'd have like to have won the competition, under the circumstances, coming second was the best I could hope for, and I was actually pretty happy with that. My game is by fair the earliest of the set in the competition and maybe it looks primitive. I do happen to think that it's the only one of the five that's really genuinely fun to play, but that's not something that can be ascertained from a casual 30-second viewing! So coming second was really pretty good.

I did meet Matthew Smith at the end – all too briefly. He was very pleasant and friendly, and I'd have liked longer to talk to him. He seemed genuinely interested in my game, and gave the impression that he'd actually played it – he tried to ask me about how I'd created it, but unfortunately we got distracted by other people and never really had chance to get into a proper conversation. What he did say was that he thought it was "definitely one of the better remakes", which I found flattering.

So anyway, overall I had a very nice time. I hope I don't seem to be whingeing in what I say above; it doesn't really matter to me that my game didn't win. I was just a little disappointed that the competition wasn't fairer, and that the odds were stacked so unevenly, because I do think that if one is going to have a competition, it should be fair. But that's just me.

Basically I had a great day. It was a genuine honour to have my game picked for the competition (and I found it installed on three of the machines in the main hall where you could play retro-games, which was also flattering) – and of course it was a privilege to meet Matthew Smith (something I never thought would happen). I also enjoyed meeting Martyn Carroll and Paul Drury… and, in particular, Daniel Gromann. Danny was kind enough to take a number of photos of me with Matthew Smith, and then he walked me back to the railway station after the event, so that we could chat further. It was great to meet him.

By the way, a video of the whole presentation was indeed made and was put online somewhere. I no longer know where it is/was, but I downloaded a copy to keep myself.

#10301 New MM version for the Atari ST (preview)

Posted by Norman Sword on 03 November 2018 - 11:22 PM

Looks great, but I see problems in how you have animated Willy.

The picture shows the four phases of Willy along the top (original)

The middle row shows the four phases as far as I can tell from your version (These are poorly scaled screen grabs)

The lower row is how I would correct the the animation. E.g. by editing the 2nd phase of animation.

The problem that I see, is caused by Willies hands not seeming to cross over the side of willies body.

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.
