Good luck! Thank you for everything. Here is some hope that your love for music and Miner Willy will at some point arrive at 50:50. Also: why did I think all these years you were Dutch?

My JSW/MM-related activity has diminished sharply in recent months. I did do some things – like finalising, together with Lemmy, the release of "Jet Set Lemmy" v. 2.0 – but that was only "a final push" to make a public launch of a project on which a lot of work had been spent in the preceding months.
My greatest regret in these last months was not assisting Hervé in any way before his release of "JSW in London". I am genuinely sorry about it, and I would like to explain the reasons behind this shocking development and behind my reduced involvement in JSW activities, which will continue in the foreseeable future.
The reason is that back in May I discovered that it is now possible to do something that I had always dreamt of, but couldn't do in the past: to turn the songs I write into high-quality recordings using the technological tools now available. I dived headfirst into this new activity, which has an enormous appeal to me and wholeheartedly captures my interest, energy and time. And I will admit something, and I'm not saying it lightly: at this time, more than JSW/MM. It is a consuming passion for me and an extremely time-intensive activity, and at present it is where I want to devote most of my spare time.
As a result of this new passion, I started releasing my music, created with the assistance of AI, on the internet on 1 August 2026. It is available at:
YouTube: https://www.youtube.com/@Daniel_Gromann
Spotify: https://open.spotify.com/artist/380jWlyChc0cA9jcNzefDw
Apple Music: https://music.apple.com/pl/artist/daniel-gromann/6792966854
TIDAL: https://tidal.com/artist/83098429
Bandcamp: https://danielgromann.bandcamp.com/
SoundCloud: https://soundcloud.com/daniel-gromann
and almost 20 other platforms.
At the moment, there are 19 publicly available songs illustrating the different types of tracks I create. For the foreseeable future, new songs will be added every Wednesday and Saturday.
The music is quite varied, but lyrics are always important to me. I write songs in my native Polish as well as in English and Spanish, with occasional songs in other languages. Many draw inspiration from musical traditions and styles I admire, particularly those of the 1930s through the 1960s and the work of singer-songwriters of various eras; others follow an entirely original path. Whatever their style or language, my goal is simply to create the kind of songs that I myself would love to discover – and that perhaps some other people will enjoy too.
I will not give up my JSW/MM activities altogether and will try to keep JSW Central updated as best I can. However, if I have to choose between music creation and JSW/MM, music will have priority. In practical terms, this means that, until further notice:
I will not create any new games of my own;
My involvement in other authors' projects will be diminished;
JSW Central will be developed mainly in "update" mode, without really adding new sections, missing screenshot galleries, etc., and its updates may be delayed;
New videos on the JSW Central YouTube channel will continue to be posted, but less frequently;
I will limit my JSW/MM activities even more strictly than before to the topics that really interest me, i.e. new games for the ZX Spectrum. The topics that I will not be actively involved in include, inter alia, the original MM and JSW for other platforms and any other non-ZX-Spectrum games, as well as very detailed musings related to the original MM and JSW for the Spectrum.
So I will still be here, but with less involvement... but maybe some of you will like my music if you should happen to enjoy the kinds of music that I love so much 🙂 .

Great news, Hervé! 🙂 
Thank you so much for keeping us updated about your projects. It is great that you are working on them, as there's no doubt that they will end up being fantastic new JSW games 🙂 .

I'm sure I saw an ad for this recently somewhere in London...
😉

Hello Everyone!
I'm starting this new thread to keep you updated on the progress of my next game "Christmas Day".

It is set for release in December 2027.
I'm incredibly excited about this project.
I need to create effects that I haven't used in my previous games.
The story:
Willy will play the role of Santa Claus. He will set off from the North Pole to deliver gifts to a small, snow-covered village.
Project 11 - Christmas Day. Version 64 [- 64 rooms 
The title screen is finished.  I'm starting to create the rooms and the guardians. The paper plan is finished.
The file is created and the rooms are ready but still empty (Just the shape of the walls and objects I want to create).
 

 
I have started working on three other projects.
I'm not ruling out the possibility of creating and releasing one of these three games next year (2027).
Provided I have made good progress on my upcoming game, "Christmas Day."
 
Project 12 -  Time Machine : Middle Ages. Version 64 [- 64 rooms   Project 10 - Journey to the Centre of the Earth. Version 64[ - 64 rooms. Project 9 - Exploration of Rama III. Version 64 [- 64 rooms. See you soon

Hello to the community and to all fans of the game JET SET WILLY !
I am pleased to announce that the release of my seventh JSW game "JSW IN LONDON" is scheduled for September 20, 2026.
The game takes place in the magnificent city of London!
You can discover its iconic landmarks as well as numerous nods to films and personalities inextricably linked to the city—not to mention a touch of history!
Naturally, this reflects my personal vision and draws inspiration from my own travel memories. I hope these references will resonate with other players as well.
I also want to point out that this game is free; these tributes are included simply because I couldn't imagine creating a game set in London without them. It is my way of thanking everyone who has inspired me—and continues to do so today. I hope it is perceived that way.
The game consists of 128 rooms.
It begins at the airport, just like my first game, *JSW in Paris*, but this time aboard a Boeing 747 SP rather than an A380.
It is possible to complete the game without losing a single life.
Three bonus rooms offer the chance to earn an extra life; you can therefore finish the game with a total of 10 lives.
This seventh JSW game was the most complex to design and required the longest development time.
I also spent three weeks in August thoroughly testing it.
"JSW in London" has been translated into five languages:
English
Spanish
Portuguese
Italian
French
I sincerely hope it will soon be translated into Polish as well, just like my previous games.
I tried doing it myself, but I wasn't at all convinced by the result.
Circumstances meant I had to handle every stage of the translation and testing myself.
It was a first for me, and it wasn't easy. I hope that for future games, my longtime friend will be able to bring his magic and technical expertise back to the project, as I really missed that. 
So, mark the release date in your calendars:
JSW IN LONDON September 20th!
See you soon.
Hervé

Apologies for the delay in getting back to you.

Been very busy at work over the summer.

Link to web version of game https://monkeyx.net/retro/games/manic-miner 

Link to the editor https://monkeyx.net/retro/games/manic-miner/editor/

Editor can help show max jumping range etc. But need feedback as not heavily tested

Working on build and release process.  Will post link to that repo next

Thanks @UncleWan, I will give it a go.
I had noticed that unusually placed block but I'm not familiar enough yet with the various bugs that can be exploited. So your gif really helps 🙂

Thank you for playing my game,MikeH!
The rooms to the right of 'Big Trouble with Little Zombie' were all created by Daniel Gromann, because I ran out of inspiration. Danny added a lot of fun challenges in these rooms, some of which require using bugs to complete.  
To reach the right side of this room, you also need to use a bug—Wiily can pass through the floor blocks when jumping to the left from a certain distance.  
I made a GIF to explain this room; hopefully it can help you.🙂

 

The only positive thing is if MS makes some kind of money from it. Can't even think it will attract new players to the original really.

I am thrilled to announce that a significant upgrade has been made to the archive of the old Manic Miner & Jet Set Willy Yahoo! Group messages available on JSW Central.
Apart from ironing out some errors, two important new functionalities have been added:
1) The search function
It is now possible to search through the messages. Several options are available: you can sort the results by "Best match" – an intelligent (although somewhat arbitrary) search – or by "Oldest first" or "Newest first". You can also tick or untick a box called "Include all messages in thread". If ticked, the search results will show not only the message or messages found during the search, but also all other messages in the same thread. You can also choose how many results should be displayed (10, 25, 50 or all).
2) Browsing through the threads
It is now possible to browse the messages by following their threads (use the "Previous in thread" or "Next in thread" arrows instead of "Previous message"/"Next message"). It should be noted that while the thread structure has been restored faithfully from the preserved files (thanks to JSON files saved by John Elliott), there were evident errors in this structure at the time when the original Yahoo! Group existed (some messages that should evidently form a thread don't, and some threads are composed of messages that should evidently be separate). Any errors that were present in the original thread structure will NOT be corrected – the intention of having it on JSW Central is to preserve the rich content of the Yahoo! archive, not to correct it.
All this fantastic work on enhancing the functionality of the archive has been carried out by my son, Michał, who is a young IT professional and who has enriched JSW Central in ways I couldn't even have imagined how to achieve – and I'm extremely grateful to him for his contribution! Michał is planning to publish some technical information about how the search engine works to produce the "Best match" results as well as about the filtering and restoration process of the original messages. When he does, I will post the link here in case anyone might be interested.
So go ahead and browse through the Manic Miner & Jet Set Willy Yahoo! Group messages archive on JSW Central like never before! 🙂

Congratulations on releasing "JSW in London",  Hervé! I look forward very much to playing it very soon 🙂 .

Hi UncleWan,
Thanks for this initial feedback on the room previews. I always try to offer different rooms from one game to the next. The London theme really inspired me.
I’m really thrilled that we released our games during the same week! It’s wonderful to see that JSW games continue to inspire creativity in 2026—a full 42 years after the original title!
As you mentioned, I’ve added a room as a tribute to that first game "Jet Set Willy 1".
Video games are considered the tenth art form.
Jet Set Willy 1 still gives me just as much of a thrill whenever I play it. In my game, the tribute room is a bonus room!
See you soon
Hervé

I used TileMap made by Simon Owen to open JSW in London. This software lets you watch the entire dynamic room layout while playing JSW. I knew I probably wouldn't be able to explore all the rooms without cheating.  
The rooms are all beautiful and very creative. I really love the JSW mural in 'Masterpiece of the tenth art'! I even saw the mermaid Maria.🤣
 

I'm looking forward to this one! It's next on my list if I can finish Plants vs Zombies.

It looks like the downloads in the Download section are not highlighted as new by being shown in the 'What's New' section after they are updated.
So, to draw everyone's attention to this recent release, I will post this message.
Version 2.0.0 of Jet Set Lemmy was released last Friday: a result of Lemmy's and my work over the last year and a half, roughly.
Please have a look at Lemmy's comments posted where you can download the game from. I will just elaborate on the game's being unprecedented in terms of in-game music variety. It features a title-screen tune and 25 in-game tunes, custom-coded in the JSW128 music format, most of which have never been used in any JSW game before. This is possible thanks to a technical solution whereby the in-game tunes are stored in Memory Bank 4 (normally used for room data), and the tune for a given room is copied to a buffer in Memory Bank 0 upon entering the room and played from there. And I believe this makes the game much more enjoyable than having the same tune throughout.
Jet Set Lemmy now also has its own page on JSW Central.

Hi Adban, 
It's great to know you are back and that you are motivated to finish "Roddënwald"! 🙂 It definitely deserves it! 🙂
If I can help with further/final playtesting when the game is ready for it, I will be happy to do it.
Also, for the record, your identity on JSW Central is established as "Fabián Álvarez López (Adban de Corcy)". I hope "Roddënwald" ("Jet Set Jason in Roddënwald" I think may be the full title, if I remember correctly) will be released under the same author, not to create any confusion 🙂 .
It's great that you're back, really! 😁

Hello there! I'm just writing to inform you that, after a looooong hiatus and several personal crisis, I think I'm ready to go back to the community and fairly motivated to finish my game "Roddënwald".

Just saying "Hello!" and, you know, greet you all, old friends and new friends-to-be!
This is Adbán, or Kórzhin iz Adbán, or Adbán de Korzy, the one and only. Reject imitations and cheap copies.

@jetsetdanny Jet Set Lemmy runs fine in TileMap, but the map layout definitely needs some fixing. The music in bank 4 means some junk rooms are added by the room scanner, but they can be removed using a layout override.

If you want to try the whole process (which should be the same for any new JSW game):
Load the tape image into your favourite Spectrum emulator. Save a SNA snapshot of the game to C:\Users\YourUser\Documents\TileMap\games\JSW128\Jet Set Lemmy.sna Ensure the snapshot name is how you want it to appear in the game browser. Save a 256x192 screenshot of the game to C:\Users\YourUser\Documents\TileMap\thumbnails\JSW128\Jet Set Lemmy.png Start TileMap and browse to the JSW128 section to find it, since it's using the JSW128 engine. Hold Shift as you double-click the game to start, which saves a map layout. Open C:\Users\YourUser\Documents\TileMap\layouts\JSW128\Jet Set Lemmy.txt to see the room layout Make fixes -- in this case you definitely want to remove the two bottom-most blocks of rooms with numbers >= 0x80 Make any fixes to the layout too, moving rooms around as necessary. In TileMap, return to the game selection and re-open the game (no need to restart the whole app) Verify the map layout is correct, repeat until happy. Take care with the layout files as the format is very strict. If it contains any format errors or duplicate room numbers the override layout will be silently ignored, and the default/detected map layout will be used instead.  If the layout feature is used by others I'll improve error reporting, rather than relying on it just stopping in my debugger.
The infinite lives and infinite time patches are detected at runtime, and if found they're available on the pause menu. For this game both were successfully detected from the standard JSW128 code. If any of the other code patches aren't compatible it'll show the missing patch details, and refuse to run the game.  In that case I can extend the patch support to fix it.
I'd be happy to accept new games and layout files, if I haven't already added them. If Pasmo hasn't mapped the games it'll take more time, unless someone involved in the development knows what the game should look like.  🙂

I have only looked at the videos so far, but that's some amazing work.

They had a place to play the original at gamescom 2026 (their page: https://www.facebook.com/profile.php?id=61550842448965)

There's another thread here: 

The release is apparently on November 5th.

I plan to buy it on Steam, evaluate for 1 hour (it's possible to refund a game you don't like on Steam if you ran it for less than 2 hours), and write an objective feedback there!
