I figured it's probably best to make a whole topic about this, seeing as it gets updated every now and then.
Anyway, Kamming recently posted
the latest version of it. Out of the lot, I'll just list a few of the more interesting ones (as most of them are translations or homebrew hacks):
Beat n Box
Fire Dragon (the original version)
Ko Ko Eo Deu Ben Ce (Korean version of Buzz and Waldog)
Master Fighter VI
Night Pearl
Powerful 255-in-1 (complete with Arnold Schwarzenegger for no apparent reason. Doesn't seem to have "Tetris III" though)
Street Fighter X Turbo 40
World Heroes 2 Pro (With the options menu)
Also funny is that my hack of Donkey Kong Country 4 is there, incorrectly listed as 2-in-1 Donkey Kong + Jungle Book (Unl). :lol:
