I hear that you are thinking about doing a lemmings 2 the tribes playthrough Flopsy. I think the SNES one is not a bad choice if you were to choose that one.
The SNES version is maybe the worst port in my opinion. So many levels dumped down in difficulty. Whole traps are missing like the eyes in the cavelem tribe. Also the music is way worse for some tribes, again cavelem would be my example here: Some uncoordinated bongos instead of the awesome tune that most people are familiar with.
I actually managed to get my recording sofware (Open Broadcaster Software) working with the DOSBOX version of Lemmings 2 the tribes. It recognises the window and the sound is also working.
