Loved the arcade verison of Gauntlet (especially the speech "Warrior is about to die!!!", e.t.c) but games never lasted long, after a couple of big early warps to about level 20ish i think, used to get killed within about 30 seconds, difficulty level was evil.
Thankfully its cheaper to play with emulation nowadays.
That Lemmings idea is really really good. It would be so awesome if someone made that.
I actually downloaded an amiga emulator recently. I've already completed Lemmings and Lemmings 2. I'm now up to the Wicked levels on Oh No! More Lemmings
I can't see Lemmings being practical on a swp, there would be either an incredibly harsh short timed version or one that takes ages to play which is not what game developers wont. Game times are usually up to 3-4 minutes and lemmings would be a lot longer than that.
