P.S. If you have already recycled the 'inactivity code' (#8B3C-3F), then you'll need to find an extra byte from somewhere else (two bytes to define LD D, #00 but you won't need the earlier single-byte LD D, A command).
EDIT: In fact, if you're trying to apply this to a Manic Miner game then you'll have to find an additional byte from somewhere anyway, as the inactivity code doesn't exist in that game engine.
FURTHER EDIT: Actually, you would have bigger fish to fry if you're trying to implement this in a Manic Miner game. The code in my previous post relies upon the minute/tick counter (#85CB in JSW) to decide when to increment the music note index. But there is no similar minute counter in the MM game engine. So you would have to introduce one (it wouldn't need a whole byte; just a single bit which acts as a flag and toggles between set & reset (probably via a XOR) every time that the Main Loop is executed.
I suppose you could use the lower byte of the air supply variable (#80BD) for this purpose - it is decremented by a value of 4 each time, so you would have to test bit 2 (AND #04) for the purpose of playing the music at the regular speed. Or you could test bit 3 (AND #08) for an even slower rendition. But then you might have an odd effect in the solar cavern whereby the music either occasionally plays faster, or else gets stuck on the same note, whenever Willy is inside the solar beam? But then I suppose that could be quite a fun, quirky effect!!

The simplest way to have a 256 byte in-game tune is this:
Extend your tune data to 256 bytes.
Then just NOP out the commands at #8B47 and #8B49.
****
However, that by itself will cause the tune to play too fast (as the note counter will be incremented during every pass through the Main Loop). To slow it down to the regular speed, a bit more editing is needed. Insert this into the range of addresses #8B40-#8B4C:
LD D, A (for the addition later on - N.B. this assumes that A is still set to zero as a result of the command at #8B3C)
LD A, ($85CB) (game_tick_counter variable)
AND #01 (test bit 0 of the game tick counter)
LD HL, #85E1 (point HL at the music_note_index variable; NB this doesn't affect the Zero Flag)
JR Z, #8B4C (or JR NZ, whichever polarity doesn't cause the first note to be missed or curtailed upon game startup) - conditional relative jump past the next single-byte command
INC (HL) - The conditional jump prior to this command will ensure that the code which increments the music note index is only executed when the game tick counter holds either an odd or an even value, thereby slowing down the rendition of the tune.
LD E, (HL) - the conditional jump above jumps to here if the condition is met
Then #8B4D onwards is as normal.
P.S. You could check that part of the Main Loop in the Jet Set Mini code to see the above in situ.

First paragraph - that's how I feel whenever I hear the short, 64-byte version of the Radetzky March in-game tune, after having implemented a 256-byte version (score courtesy of Richard Hallas) in Jet Set Mini.
How to achieve a 256-byte tune? I'll get back to you - although the answer may be in an earlier post of this thread? 

If I Were A Rich Man.
And ITHOTMK = In The Hall Of The Mountain King.

You're most welcome! 🙂

The players have been swamped by the authors' prolificacy? This could be it... 😉

In the projects I've been involved in, this mechanism (turning the tune on at a specific moment even if the player was playing with the music off) has only been used for the game's completion, when a new - 'victory' - tune kicks in upon reaching the toilet. I believe you actually provided the code to enforce this, Ian - for which I continue to be grateful! 🙂

Thanks, Ian! I must say that now when I listen to the original 64-byte-long version of "If I Were a Rich Man" in other games (for example when recording their RZX walkthroughs), it seems very incomplete...
Ian, in one of your projects, you applied a 256-byte-long in-game tune. Could you explain how you did it (from the technical point of view)?

Great minds... 😁
What's "IIWARM"?
IIRC in my setup the note index is set to #FF when the tune is supposed to start from the first note, so that when the in-game music note index is incremented on the first pass through the code *before* the first note is played, it is incremented from #FF to 0 and so the first note is not missed.

An exceptional year indeed!
It's possible the lack of feedback is due to such a busy release year? I know that I have a backlog of games to check out, I've just not got around to playing yet. Either way, top-hats off to a great 2023 with some amazing games released. Congrats and thank you to all involved.

I do agree with you here.
I am quite guilty of this too sorry 😞
But on the whole feedback and thoughts (good or bad) are appreciated in general.
León Willy has a low download count here for some reason currently, however I tend to not judge by that because its available elsewhere and no doubt some other sites will also host it and other files too.

In the case of 'In the Hall of the Mountain King', I believe I did that classical piece of music justice in 'Manic Mixup' - implementing a quite faithful 128-byte loop during gameplay (which doubles in speed of play when the air supply in each cavern reaches the 'red zone' - replicating the way that ITHOTMK gains pace towards the end), and a coda that is played during the 'cavern completion' sequence (when Willy goes into a flashing portal), which matches the finale of Greg's original composition. 😎
I look forward to hearing what you've done with it, and also your extended rendition of 'If I Were A Rich Man'. 😊

I devised a similar setup for my long-gestating (currently in abeyance) project: 'Willy's Recurring Nightmare':-
If Willy enters a new 'tune zone', the music note index is reset so that the new tune starts from the first note. (Incidentally, the music note index is set to 0, not to 1 as it is in the original JSW, in which the first note of IIWARM is curtailed when you first start playing a new game.) But if you enter a new room within the same tune zone (or lose a life), then the existing tune carries on seamlessly.
I also added another feature - if you enter a new tune zone, the 'tune on/off' flag is reset so that the new tune starts playing even if the player had opted to turn off the music whilst Willy was in the previous tune zone. I figured that this would increase the exposure of the individual tunes - I appreciate there's a danger that it might annoy a player who wants to play without any music, but then they always have the option of just muting their laptop (if they're playing on an emulator, as most people do these days).

I posted this video (or similar) into the FB 'Central Cavern' group the other day. Reasons mainly:
> The video is from the last release version
> It it on here viewable by public
> Shows the game in "random by room" mode
> Will hopefully encourage more to try the game too
 

Thank you as always for the updates. 🙂

Yesterday I posted my last video for the year on the JSW Central YouTube channel. I'm up to 123 videos posted so far, so about two-thirds of the way of presenting walkthroughs of what I classify as new MM/JSW games.

Some comments:
"J4 (The Fourth Remix)": I re-recorded the game, improving my completion time (in relation to my earlier walkthrough still hosted on the RZX Archive) from 9969965 to 9971648.
"Manic Miner - 2000": I re-recorded the game, improving the completion score by 2418 pts., taking it up to 38 438 pts.
"Party Willy" SE (all three games): I used my RZX walkthroughs recorded back in May and June 2007 (considering them to be 'good enough').
"Lena vs Margo": I re-recorded the game, bringing down my completion time from 14:20 to 14:18.
"Jet Set Basic": I used my RZX walkthrough recorded back in January 2008.
"willy to the rescue!": I re-recorded the game, bringing down my completion time from 8:57 am to 8:42 am.
"Soul Miner": I completed and recorded the game for the first time ever. Planning an optimal route was the biggest headache (an important feature of the game is teleporters, which are very numerous and constitute a significant part of Willy's progress), but I think I got it right, achieving a completion time of 8:07 am.
"Manic Miner C.S.S.": This is the game that has so far been known as "Manic Miner: comp.sys.sinclair". I have changed its name on JSW Central (in all references that are made to it), because I consulted the original documents related to it (its website, Readme and the author's old posts about it) and I am positive "Manic Miner C.S.S." was the name its author (Nigel Fishwick, aka FishyFish) used when he created it back in 2002. I believe it was christened "Manic Miner: comp.sys.sinclair" by Andrew Broad when he placed it on his otherwise excellent list of MM and JSW games, and then the name made its way onto WoS, SC and other sites.  But it's incorrect, not what the author called the game, so I have corrected it. I re-recorded the game, improving my completion score by a mere 350 pts., taking it up to 36 536 pts.
"Marina: The Fire Quest": I re-recorded the game, bringing down my completion time from 14:07 am to 14:06 am. I am particularly proud of this, as I initially thought improving the completion time in such a small game (just 6 rooms) is not possible. It turned out to be possible thanks to some jumps from ramps which allowed me to collect some items via these jumps from below, instead of going onto the platforms they're on and outmanoeuvring the guardians there.
"Clopit!": I completed and recorded the game for the first time ever, achieving a completion time of 7:23 am.
"Jet Set Willy: Fucked Internet Remix":  I re-recorded the game, bringing down my completion time from 8:09 am to 8:06 am.
"Jet Set Willy: Fucked Internet Remake" and "Jet Set Willy: Fucked Internet Resurrection":  I used my RZX walkthroughs recorded back in March 2007.
The videos of the last three games mentioned (which together form "The Fucked Internet Trilogy") have been censored by YouTube as age-restricted and can only be watched once you confirm your age by logging in. I am not happy about YouTube's policy on this (I believe there are far more serious problems in the world than someone, even a minor, using the F word), but I can't help it. I can only say that in the future I intend to make all the videos available for download, and then, hopefully, everyone will be able to download also these three without any restrictions.
All of the newly-recorded RZX files can be downloaded from the games' respective pages on JSW Central.
Creating and adding videos to the JSW Central YouTube channel will be one of my JSW/MM priorities in 2024. It will remain a priority until video walkthroughs of all games I classify as new games are presented there. I will then continue with other videos, prioritising selected minor versions of MM and JSW or some highlights from their gameplay (like new rooms).

2023 has been an exceptional year for the MM and JSW games for the ZX Spectrum 🙂. It saw the release of several brand-new games:
"WiLLY iN ThE MiRRoRVeRSE" v. 2 was released by Carl Paterson on 10th February (this being the first public release of the game). The release of updated v. 3 followed on 8th December.
"Jet Set Willy: Role Reversal" was released by Sendy (Alex Cornhill) on 11th March.
"Manic Person" was released by Sendy (Alex Cornhill) on 7th October.
"León Willy" was released by Pedro Magallares Ocaña on 10th November.
"JeT SeT JnR aNd ThE CuRsE oF ThE PhArAoH" v. 2 was released by Carl Paterson on 22nd  December (this being the first public release of the game).
 
Furthermore, "Manic Miner 40th Anniversary Tribute" ("MM40th") was released by Bob The Polar Bear on 24th August. It could be debated whether it should be considered an entirely new game or a continuation of his project whose earlier 'incarnations' are "Manic-4-Noobs" ("M4N") and "MANIC-minor" ("M-m").
 
2023 also witnessed  some releases of new versions of games originally released in previous years:
"Manic Jet Set Willy" v. 3.00 was released by Norman Sword on 1st January and v. 3.01 followed on 7th January.
"AmAZiNG WiLLY" v. 3 was released by Carl Paterson on 22nd January and v. 4 followed on 2nd December.
 
Furthermore, a minigame called "Jet Set Willy: Key Code Edition", based on the original "JSW", was released by Andy Ford on 24th/25th March.
 
Finally, bug-fixed versions of "Manic Miner 128" (one based on the Software Projects edition of "Manic Miner" – originally created by Mihai Novitchi, the other one based on the Bug-Byte edition of "Manic Miner" – originally created by Bob Fossil) were released by Bob Fossil on 5th/6th May.
 
I should also note that Sendy's "Strangel 2" is in its beta stage and, as a playtester, I can say it's an incredible game (using the JSW64 V game engine), which brings JSW gaming to a whole new level. The game has not been released yet, but it was effectively created in 2023. I do hope it will be released in 2024 (with some additional enhancements that I will be happy to contribute to as much as possible).
 
I also believe that Jet Set Willie's first JSW game is also in its beta stage, also created this year which is just about to end, but I'm not sure how much info I can disclose about it - perhaps Willie will comment on it if he so wishes.
 
All of these developments show that the MM/JSW-editing scene is still very much alive 😁. I just wish there was more feedback from the players - typically, except for some initial reactions after the game's release there is hardly any info if anyone has actually completed the game. There have been some exceptions, but, generally speaking, what I would call "solid feedback" has been scarce, which is a pity, because, as noted in some of the older Readmes, "the biggest gratification and encouragement for anyone designing free games is to know that someone else has played them!"
 
Happy 2024 to Everyone! 😊

Thanks for all the info, Norman Sword!
I take it a new version will be released at some point. I am looking forward to it 🙂.

The attract mode is a great feature. The changing of the screens is a little too fast for me, I think it might work better if it was slower. Just a personal preference 🙂.

Yes, you do!

I hope 2023 will be remembered, besides other things, as the year of an "explosion" of in-game music in ZX Spectrum games using the MM and JSW48 game engines.
I was privileged to work on the "postproduction" of some of the fine games that have been gamma-released (or updated) this year and I composed in-game tunes for most of them. In total, between September 2022 and December 2023, I coded more than 90 in-game tunes that had never been used in any MM or JSW game for the ZX Spectrum before. They are 128-bytes-long, i.e. twice as long as the tunes in the original "MM" and "JSW". 
76 of these brand new in-game tunes (if I have counted correctly) have been made public and can be listened to while playing Carl Paterson's "AmAZiNG WiLLY" v. 4, "WiLLY iN ThE MiRRoRVeRSE" v. 3 and "JeT SeT JnR aNd ThE CuRsE oF ThE PhArAoH" v. 2, Sendy's "Manic Person" and Pedro Magallares Ocaña's "León Willy". There are also more than a dozen tunes I coded that have not been made public yet but that are ready to be used in future projects (including an individual game project of mine which I hope to continue at some point, hopefully in 2024 if real life circumstances permit).
In addition to these brand-new tunes, I creating extended, 128-byte-long versions of "If I Were a Rich Man" (the in-game tune from the original "JSW") and "In the Hall of the Mountain King" (the in-game tune from the original "MM" and "Jet Set Willy II"), both coded by Matthew Smith, and a couple of extended, 128-long versions of other previously existing tunes. And a 64-byte-long rendition of Chopin's Marche funèbre (preceded by an alarm sound) for rooms designed as multiple-death traps.
I had always wanted to enrich the music in the MM and JSW games, but for many years it seemed to me that coding this music is very difficult. Then I coded my first in-game tune in 2020 while working on the 48K Edition of Fabián Álvarez López (Adban de Corcy)'s "Madam Blavskja's Carnival Macabre" and then suddenly I realised how easy it was. "Easy" thanks to Richard Hallas's document "A Miner Triad. Music in Jet-Set Willy and both versions of Manic Miner" which is instrumental (pun intended) in managing and coding the music. I did have to go through a learning curve (which is evidenced by how some tunes are improved in version 4 of Carl Paterson's "AmAZiNG WiLLY" in relation to their original editions in v. 2), but now I am generally able to code a tune in, say, 15 minutes if the melody is easy and I know it well (and in a couple of hours if the melody is difficult and I have to refer to the musical notation).
Most of the tunes I have coded are melodies that come from various areas of the music I love. This includes (but is not limited to) old American folk music, popular European and U.S. music from the 1930s through the 1960s, various songs from Poland, my home country, and from the Spanish-speaking world. A couple of compositions are entirely my own: either renditions of tunes I believe I once created ("I believe", because I can't be quite sure I didn't hear them, or similar tunes, somewhere), literally decades ago, or coded in recent months specifically as JSW in-game tunes.
In the future, I intend to create a file which will be a sampler of my in-game music compositions: technically a JSW48 game file, but with only one room and a possibility to input the address from which the in-game tune is to be played, thus making it easy to listen to the various tunes. It will also include a detailed description both showing what each tune is and pointing to where it resides in memory (so that the code can be easily copied to be used in other projects). This will have to wait until my individual game project that I mentioned above is released, as I definitely want to include the currently unpublished tunes I have ready for it in this future music sampler.
"AmAZiNG WiLLY", "WiLLY iN ThE MiRRoRVeRSE", "JeT SeT JnR aNd ThE CuRsE oF ThE PhArAoH" and "León Willy" also feature brand-new title-screen tunes I coded (while Sendy's "Jet Set Willy: Role Reversal", which otherwise has no in-game music, features a 128-byte-long version of "If I Were a Rich Man" as the title-screen tune). 
The final note on the music developments in 2023 is that these recent projects feature new code responsible for initiating the in-game tune from the first note. This activation takes place if a different tune was playing before Willy entered the current room or if the same tune was playing in a different mode (in some of these games the tunes play in various modes, e.g. faster or more slowly, or either in their full 128-byte-long versions or in the shorter 64-byte-long versions). Notably, if the same tune was already playing in the same mode, the code ensures the seamless continuation of that particular tune. This is a valuable enhancement of the musical experience (if I may say so myself).
Should anyone want to use any of the tunes I coded in their projects, I will be more than happy for this to happen. Please get in touch if you want specific info about any of the tunes 🙂 .

You're right, you can't see the real portal when you lose a life there.

That's as close as MM gets to quantum physics, I guess! 🤣
