Just went through and did a few more of Psycho. Most interesting being 11 and 20. The variety of different solutions to 11 (I know of at least 3) allows for quite a lot of skills to be eliminated - only 2 climbers, 1 bomber and 2 builders remain in common between all solutions. During the course of finding these I also stumbled upon a 9-skill solution, based on the "bridge the gaps then go all the way with one miner" solution.

20 actually turned out to be quite fun, I expected it to be one of those hellish ones. Eventually I narrowed the skills you can't live without down to 2 climbers and 5 builders (using a slightly different route - block off the far bottom-right without using builders to do it, as well as mining off the right edge of the obstacle in the bottom middle and digbashing a bit to make it non-climber-friendly, it's two builders to get up to that, two more to get up to the next level, and one to get across to the part where the exit is at the top. You have 9 of each destructive skill, plus builders can be substituted in some cases, so eliminating those is easy, and very few if any solutions to this level use floaters or blockers in the first place - bombers are obviously not needed since it's 100%), and minimum skills to 17, though I think I may be able to improve those to 1 climber + 5 builders and 15 skills respectively.

EDIT: Psycho 20 with 1 climber confirmed. Still got to try the 15 total skills solution.
Perhaps the awesomest part is that despite using only one climber (compared to the five or so in the original solution - I don't know if I'd say "intended solution" as this is meant as one of those levels that's more open-ended as to how you solve it within the restrictions given), it STILL requires the key element of the original solution - the use of multiple lemmings working on seperate sections of the path at the same time.

EDIT: I have closed this topic as it'll be easier to keep track of these things via the Replay Database, once the Lemmings Plus games are added.

Here's some challenges for my packs Lemmings Plus DOS Project and Lemmings Plus II (and the bonus pack), and Lemmings Plus III.

(Quick download link: Lemmings Plus Twinpack)

Feel free to ask for a replay for any of mine if you want. And of course I'll update the list with any improved results.
Anything listed in parenthesis means (for the can't live without) means that the skills that aren't listed haven't been properly checked yet, and the values given are minimums for those that have.

Just to be clear: These challenges are based on the final standard release of each game (NOT the NeoLemmix versions; or in LPIII's case, not the versions included in the general NeoLemmix update collections). In other words, the correct versions to use for this topic are:
LPDOS V9
LPII V4/2/4*
LPII Bonus Pack V2/2/3*
LPIII V3 / V1.15n**
LPIII Bonus Pack V2 / V1.23n-C
HLP V1 / V1.24n-C
LPO V2 / V1.27n-B

* These versions of the LPII and LPII Bonus Pack players don't show any version number at all. One way to test if you have these versions is to try accessing a secret level with cheat codes; this is not possible in any traditional Lemmix versions except these ones.
** Note that the LPIII player reports itself as "Levels V2 Player V1.15n". However, if the Player version is V1.15n, then the levels are V3; this is just an incorrect text in the player.

Just for in case any solutions might rely on finer details of the mechanics, here are the mechanics details for LPDOS and LPII:

Lemmings Plus DOS Project
- Uses Orig mechanics as a base
- Bombers skip the countdown and go straight to "OhNo" (or the explosion, if they're also fallers)

Lemmings Plus II
- Uses OhNo mechanics as a base
- The pause-for-time glitch does not work
- The nuke glitch does not work
- The one-way-right miner glitch does not occur (right-facing miners can dig through one-way-right walls)
- All other glitches (eg. sliding) still work

I'm wondering, are there any tools out there to rip (and resize - without any antialiasing, preferably) the terrain pieces from the Ground0o/Vgagr0 files from DOS? (If not, I might look into making something myself... I know there's extractors for these files, so then it's just a matter of converting them into GIF.)

Just because I remember hearing the hi-res graphics from the Windows versions (which is what Lemmini extracts) aren't always perfect.

Any chance you can incldue a 60/120px fall guide as well? I generally prefer to work with Orig mechanics...

Awesome! That was one of my favorite features in Cheapo.

Okay, I extracted the data files from it and I figure, may as well upload them. Feel free to do what you like with them.

Contains LEVEL000.dat through LEVEL009.dat as well as ODDTABLE.dat (since LP DOS makes use of Oddtable for repeat levels).

Should be noted that because of this Oddtable-use, not every level is in there. Specifically, where a level has a repeat version, only the repeat version is included. For the No Salvation levels, 3 are included as is, the other two aren't (since the LPDOS Lemmix Player uses Oddtable for them). The removed level "Phase Rotation Syndrome" is in there as well, since while it was removed, it's earlier repeat wasn't.

All levels are the same versions as in the newest version of the player, so it includes the new levels like Russian Rescue and the updated Coalburner.

If anyone's playing them in anything, just keep in mind that these levels are designed for ORIGINAL mechanics, not OhNo/CustLemm. This can make a difference in some levels which are specifically designed with Orig release order in mind (for example, Shooting Star) or levels with falls that have been carefully adjusted (for example, Not Gonna Work or To The End!). No new backroute fixes either, just those already included in version 7. There's also one mechanics change unique to the Lemmix Player - specifically, bombers are instant rather than having a 5 second countdown. No levels rely on this though; it just cuts out the need to time then. (EDIT: Actually, I think I may have set the fall distance in LPDOS even *less* than what it is in Orig, I could be wrong though.)



Something interesting, when I extracted these, I found a few of other people's levels had been compiled into the EXE too. There's no way to actually access them, but the data's in there. I think it's because they were in my Lemmix source code folder back in the day because I always used to compile Lemmix players with like 5 or 6 packs of people's levels, in order to play them... and somehow they ended up in the LPDOS EXE too. But - as I said - you can't actually play them in any way, they're just embedded in the EXE. I recognize some of them as being by Insane Steve, but most of them I have no idea who's they are. Apart from Phase Rotation Syndrome, there doesn't seem to be any of *my* levels hidden in there other than the ones that are actually part of LPDOS.

The level editor part?  Maybe, haven't tried it.
The playing levels part?  No.  It doesn't work.

Okay, this is OLD but I have to say... I personally have run Lemmix on WINE in the past and it definitely works. Sound support is sketchy (but then this also happens on some Windows Vista/7 systems), but the gameplay is perfectly fine. Though I haven't tried test play mode from the editor; I'm basing this on the Lemmix Player.

The SMS version rendition of "London Bridge", as well as the musics unique to that version, are pretty good.
