Fun(?) fact: if you extend the Bathroom ramp all the way down to the floor, and put a hole in the upper platform directly above the toilet, then during the toilet run Willy will run up the ramp and drop through the hole... But will disappear halfway through the fall... then appear suddenly in the toilet. (ie Without visibly falling through half of the height of the room.)
This is because the code which tests for Willy's coordinates at the end of the toilet run doesn't check which vertical half of the room he is in.

I do too. It was a bit different back then with real hardware. Yes I did have a multiface which could do snapshots however the time taken to save/load was about the same as the whole game if not more (if memory serves, it would take the whole lot of ram, with or without display file) , it was more for editing things for me.
Having said that and its a different topic completely in a way, I do wonder how far we can now get on some games without -any- rollback or otherwise. I did try this with other machines (non ZX) versions with some success. Perhaps a Christmas idea.

Congratulations for such a finding! 😃🙂 
Boulder Dash on Commodore 64 perhaps? There are hundreds (at least) of homemade versions available on internet.
I haven´t checked though when the last ones have been made.

Yes it must happen Andy! Would be great to see it - can never have enough versions of JSW!

I did have a special (sort of) JSW game in the works since perhaps April / May / June this year but had a bitlocker accident and lost the later builds, I do have an earlier build but no notes to go with it.
I had planned on (you've maybe seen on Spectrum Computing a year or so ago) the comparisions between platforms, I had thoughts of doing this with JSW too, only 'officially' released versions as such.
There's still a bit of time 😉 🙂 

Just wondered was there no celebratory thread about JSW being 40 years old this year?
 
I didn't have time to check the forum much a few months ago, just wondered if I missed some
kind of celebration about it?
 
40 years is a long time for any game to have a playable lifetime, I know there are plenty of other
classics from 40 years ago, not sure if there are any that are still being developed using the same
engine etc, JSW maybe unique in that respect? Sure I will be proven wrong!

Another MSX JSW map, this one is quite similar but highlights where the objects are. I noted no wording on the water tiles in Hades, however that might be the map makers decision unless slight variations exist...

I can´t help it, the Sinclair Research is one to blame. Or alcohol.
😄

Thank you for your feedback. 🙂 
Perhaps I should add a warning to my game´s front inlay, "Warning! One game player has reported illness when he played while being drunk. Please stop playing immediately if are drunk and feel any symptoms." 🤭
The backgrounds of Willy games seem to be "empty", not all of them, but some at least, the platforms and walls and items being the only visible things among the guardians, everything else being usually just empty black. I wanted to bring the missing "3D" there, all the missing things, like the mountains, the clouds, all the scenery "behind" the "nearest" platforms. Also, in some rooms you can walk "further" away from the tv screen and back, too.
 

Finally downloaded this and played it a bit. It is different! The graphics are certainly different looking too. Don't play it if you are drunk the colours will make you ill!
But thank you for it!

Just thought I would mention it here, saw it on the Spectrum Computing forums in case
anyone missed it. It's made with ADG so not a mod, a new game.

wow that's so hard to have a account in this website! I have to use the VPN to cross the internet great wall so l can post what l want to say in here.
l first seen the game "jet set willy"about 3 years ago,l love the platform games like this so l want to learn it more.without Google(china banned Google!),the only l can use is Bing .but that's enough.
l often play jsw on the online emulator like "zx art"or"qaop".after a few months,the more versions l found.like java version or PC version by Andy Noble(very good),and z88 version(l can't believe that it can play on a so narrow screen!amazing),there are lot of versions that l can't type them here.
manic miner?good game .l even write a "Baidu Baike"(because China has not wikipedia,we use Baidu Baike as instead.)about the MM!
https://baike.baidu.com/item/疯狂矿工/1186578?fr=ge_ala
above is the Baike l wrote.at 2019.there are still some wrong in it,😂.
l said too many but l can't even create an account because l can't pass the security check😅,but it is not important.just want to say that l love MM and JSW.And l am happy to see that there is a forum!
thanks every much
(if l have some grammatical errors ，please dont care😂l only learn English when l was in senior high school)

Thank you Spider😊, I had a lot to say, but I ended up deleting them. The bottom line is: I think my difficulties are nothing compared to what I found here. It's nice to have like-minded people.

Hi UncleWan, welcome to the forum! 🙂 It's great that you've found this place, been able to overcome all the technical difficulties and can now post here.
I find it amazing that you like MM and JSW while you first saw JSW only about 3 years ago. This actually gives me hope that some people in the future, long after our time, will still like the Willy games, which of course will be to them like perhaps us reading ancient literature or something.
I've had a look at your Baidu page. Interestingly, when the page is translated automatically from Chinese to English, the game's name becomes "Crazy Miner". That's an interesting twist on the title 😉 .
So thanks again for joining the forum and we look forward to the (unexpected, to be honest, while positively exciting) feedback and input from China!

Must admit I knew most but not all of these methods, although it was not something I had really thought about doing or trying.
It is interesting to see some variations however. Thought I'd share here. 🙂

One of Matthew's early games, the Spectrum version is readily available but this was not:

An interesting read at least.

Submitter Jet Set Willie Submitted 09/18/2024 Category Jet Set Willy [Remakes]  

@DigitalDuck A few years ago now I had a very very old memory of playing that game (when it was new!) at an arcade on holiday but moving back to recently I could not remember what it was called but the tune did stick in my head. I know there's two of them , the original and the 'new' , I actually have it on Mame and play it every few weeks. I'm still terrible at it! 🙂 Also its "another good Z80 CPU" game too.
 
 
 

Further to my post on page two here  , I decided for no real reason to change the scoring and add a bit more air, as well as compress the code to reduce it's loading size. There is a lot more scope to optimise this, it is starting to 'click' now properly with me.
For now , two identical versions with the increased bonus/air , one with a loading screen and one without.
Without screen$
MM_SP_Faster V3_EXTRA_BONUS_WITHOUT_SCR.tap
With screen$
MM_SP_Faster V3_EXTRA_BONUS_WITH_SCR.tap
The game code is identical in each of these two. For reasons of sanity I've named it 'V3' as the one in the linked post is V2
And a quick playthrough:
MM_SP_Faster V3_EXTRA_BONUS_WITH_SCR.rzx
.rzx recorded with Spectaculator, it should play back fine in most other emulators I expect.

Addendum - I wrote the cpc version of Jet Set Willy

The Title music is Moonlight Sonata and was writen by Beethoven in 1801. So slightly before Mr Wetheril came along.

The in game short tune is by Mr Wetheril.

Red, thank you for this version of MM, I really like it, the difficulty level is spot on! Excellent, I have been
playing it, just right for me!
