(since Lemmini uses the Win95 version's levels, which are identical to the DOS versions)
I'm sure you're right, but people have actually checked that they are in fact identical including things like missing water (compared to eg. Amiga), or how DOS have easier stats on certain levels like in Steel Mines of Kessel?
I'm pretty sure the Lose 2 solution to "Save Me" requires steel glitches. It involves building left from the start, and to do that you need to dig through the left edge of the steel to get to a lower starting point.
The funny thing about that one is that in DOS, you can't stretch your builders going left as much as you can going right. But that may not be the case for Lemmini (I never played it). I seem to recall that in versions like Mac where the stretching is equal in both directions, you can in fact build left on that level without having to dig down the left edge of the steel (which is actually pointless in many versions simply because of the presence of water that's also missing in DOS version, though probably doesn't apply to Lemmini version?).
That being said, building left is just one part of it, so it's still not clear whether you'd have enough builders left over to also deal with turning the freed right-facing blocker you would inevitably have on the starting platform, given that without steel glitches you'd also have to place the blocker on an extra build brick just for him to be freeable.
Anyway, challenge solutions tend to be particularly sensitive to the details of game physics. Even a glitch-free solution might not work out in Lemmini due to minor timing or pixel differences (eg. in position/shapes of bash/mine strokes). And that's saying nothing about any unique glitches in Lemmini. This is why I always insist on keeping separate statistics for each version when it comes to challenge-style solutions.
The lose-1 solution for "From the Boundary Line" on DOS does rely on a trick/borderline glitch that allows a climber to go in sync with a basher (he'll keep climbing the edge of the in-progress basher tunnel, then the basher's next stroke free the climber without him hitting tunnel ceiling and turn around, and the cycle continues). If that trick doesn't work in Lemmini you'll likely lose 1 more.
"POOR WEE CREATURES" I seem to recall also relies on a (different) climber glitch for DOS's lose-10 solution.
