I was wondering do all those glitches work on the SNES version?
A good number of glitches in DOS Lemmings do carry over to the SNES, including the sliding glitch, stuck climber glitch, blocker pushing lemmings into/through walls, steel destruction glitches, blocker canceling steel and traps, etc. However, I don't have a definitive list at the moment as to exactly which glitches work and which doesn't.
There are also some very significant differences between SENS and DOS Lemmings: direct drop doesn't work on SNES, you can't change release rate while game is paused on SNES, the timer runs out faster in SNES (I think 15 or 16 frames per game second) relative to DOS (17), etc. There are also more subtle differences like how terrain is removed by miner, and how a bash stroke on SNES takes out one more column of pixels than DOS.
Because of these and other differences, I always insist on keeping separate records for each version of Lemmings, especially since with challenge solutions they can often be very sensitive to the subtlest of game-mechanics differences.
I think most of the DOS Lemmings results for undamaged should carry over to SNES. If I have time I can take a look and see whether there are any differences worth noting on this thread. I might also see if I can verify a few of the DOS glitch solutions on SNES.
