There aren't any Genesis musics. The order of the tracks depends on whether the person playing has also got the DOS Music pack; tracks 1 to 17 follow the DOS order if the music pack is present, or the Amiga order if it isn't. Tracks 18 to 23 are the OhNo musics, which are the same order in either case.

However, if you want specific tracks, you can include them with your pack - if you're using the Flexi player, you can build whichever tracks you want into the EXE; if you're using (Neo)CustLemmix, you'll have to include them as either IT or OGG files. Name them "track_##.it" (or "track_##.ogg", where ## is the number you want that track to be. If you have both an OGG and an IT file for the same number, the OGG file has priority; and looping OGGs are supported.

Note that single digit numbers should have a leading zero; eg track_01.it not track_1.it. Three-digit numbers are fine if you need that many (or just want to use high numbers); so track_150.it is fine. Note that the highest track number you can use is 252; the music number can't be set higher than 255, and numbers 253 to 255 have special effects (as does zero):

0 will just use the standard "rotate through the musics one by one", or in Cust, "choose a music at random"; in both cases special musics will be played if certain gimmicks are set
253 is the same as zero, but it won't play a special track on gimmick / frenzy levels
254 plays the Frenzy music
255 plays the Gimmick music

(If you want a custom Frenzy or Gimmick track, the filenames to use are "frenzy.it" and "gimmick.it" (or .ogg).)

For reference; the special music on gimmick levels is determined by:
- Does the level use the SuperLemming or Frenzy gimmick? If so, use the Frenzy music.
- Otherwise, does the level use any gimmick other than Bait-and-Switch or 80px Fall? If so, use the Gimmick music.
- If the level doesn't use any gimmicks (or only uses Bait-and-Switch and/or 80px Fall), just play regular music.

Well, my idea was that the filename doesn't matter; it just stores a username in the file (which can be any character). Thus, you just need to generate a default filename somehow. It doesn't really matter what this is either; it could even be random. Thus, a hex representation or a hash would just be the simplest way to generate one, without having to worry about which characters are used.

You could always store somewhere in the settings which username is active by filename (though I guess this could get complicated in itself).

Why not just save the filename as a hexidecimal representation (or a hash) of the name altogether? That should be simpler and avoid having to deal with what characters can and can't be in filenames on certain systems.

IMO, most gimmicks are obvious almost right away (and indeed, that's how I intended them to be), with the obvious exceptions of the ones first used in Sneaky 4 and Playtime 10 (and, in a sense, Dodgy 18). The player still has to work out how to deal with the gimmick (or in many cases, actually make use of it rather than just working around it), as well as work out the exact details of how it functions - all they're given in most cases is a brief overview of the concept.



For LPII, the levels that were modified are:
Cheeky 2 - Tidied up the one-way arrows
Cheeky 3 - Tidied up the one-way arrows
Cheeky 8 - Majorly decreased the difficulty (save requirement reduced to 40%, skillset increased to 50 of each)
Sneaky 6 - Tidied up the one-way arrows
Cunning 9 - Replaced fake exit with the fire object
Cunning 18 - The entrance on the right side is now left-facing
Cunning 19 - Majorly increased the difficulty (save requirement increased to 100%, first four skills reduced to 0 each, last four to 2 each)
Genius 2 - Somewhat increased the difficulty (save requirement increased to 100%)
Genius 13 - Somewhat increased the difficulty (save requirement increased to 85%; yes, this is possible on the NeoLemmix version*)
Genius 20 - Slightly moved the exit position to keep it in line with certain terrain features
There's one other level too, but I'll leave that one as a surprise. It's very noticable.

* I actually can't think of any reason why this 85% solution wouldn't work on the traditional Lemmix version too (give or take 1%), though I didn't try it. If it does, then this is a MAJOR oversight by all of us - the current record stands at 79%! EDIT: I checked, and it won't work on the traditional version due to a difference in the skillset (which was nessecary because the traditional version's solution won't work on the NeoLemmix version due to differences in builder mechanics). However, I can confirm 86% is possible on the NeoLemmix version, though I don't plan to change the requirement to this, it's fine as it is.


For the bonus pack - I haven't actually made the modifications yet, just identified where they're needed (and this doesn't include Rush or secret levels as I haven't looked at them yet):
Reverse 6 - One less builder (as it's not needed in the NeoLemmix version)
Flight 3 - Tidy up the one-way arrows

The Eraser - When assigned, it erases any steel areas, traps, or water within a certain radius of the lemming.

The InvinciLem - A lemming given this ability simply cannot die.  Traps, water, and splat falls have no effect on him.  If he falls off the bottom of the screen, he will re-appear at the top.  (I can think of a zillion uses for this last feature alone.)

The former is somewhat similar to the Mechanic skill in NeoLemmix; the last part of the latter exists in NeoLemmix but as a gimmick rather than a skill (if you aren't familiar with NeoLemmix and/or the Lemmings Plus series, a "gimmick" is a twist to the mechanics that applies to an entire level; they vary from subtle changes such as how the skill counts work, to things as major as having to kill the lemmings instead of save them, or even having zombie lemmings - the latter has an entire (small) game built around it).

Indeed it should. I'll make sure to fix that in the next update.

They'll still be included in the same way they are now.

Testing is up to Psycho 21 now. A few levels have had some changes; two relate to either being impossible or near-impossible under NeoLemmix mechanics (you have to keep in mind; the last time LPDOS was fully inspected under NeoLemmix mechanics was, IIRC, before LPIII was released, and there have been quite a few small mechanics changes since then), while others are some difficulty tweaks on levels that are excessively easy for their position. One is a backroute fix I couldn't resist applying.

The full list of changed levels so far is:
Danger 23 - The aforementioned backroute fix. Also affects Wimpy 25.
Danger 24 - Made this level MUCH harder.
Psycho 5 - Made this level slightly easier (it's still very hard).
Psycho 13 - This level (or at least its intended solution) was impossible under NeoLemmix mechanics in its current state. Also affects Medi 1.
Psycho 14 - Made this level slightly harder.
Psycho 17 - Made this level slightly harder.
Psycho 18 - Removed one skill that isn't nessecary to the solution and could potentially open backroutes (though I'm not currently aware of any).

EDIT: One other level had a change, albeit a purely cosmetic one - Psycho 30's screen start position had become messed up somewhere along the line; it's been set back to what it should be now.
