haha, I was so proud of my 76/80 solution...
Interesting you call it "your" solution...just curious, are you Don P. Fortier, aka "LemMaster Don" from alt.lemmings? Because it sounded like he was the guy who first found the 76/80 solution for Mayhem 29.
Well, I called it "my solution", but surely I'm not the first. Actually, I got the idea of building to the left from some guy called dfoofnik on YouTube. Figured the rest out by myself, but he gave me the biggest clue
As for Don P. Fortier, no, I'm not him. But, now that you mention it, I recorded the 76/80 solution and uploaded it to YouTube as a video respose for a 75/80 solution of some guy called "LemmingsMaster". Maybe he's the same guy? Anyway, he said he couldn't perform the 76/80 solution because there's water in the bottom on the SNES version.
As for the 78/80 solution... bashing to free the first blockers... I'm still clueless... how can you save the rightmost blocker from falling into the void, since he is facing to the right? How do you manage to bash underneath to free them? Damn, you guys are truly masters. I still can't figure it out.
