I have been collecting ROM files for ages. Now I have all of my emulators with complete ROM packs - including ROM hacks - for NES, Famicom - Translated, SNES, Vectrex, Virtual Boy, Commodore 64, MAME, Atari 2600, 5200, 7800, Jaguar, Lynx, Genesis, Saturn, Gamecube, N64, Gameboy, Spectrum, Neo Geo and more.
It is all packaged into one frontend, complete with box art for every single game.
What should I play?
I just started Phantasy Star IV on the Genesis. I never played a game in that series before, but after an hour or so I'm liking it a lot so far. Really good old-school RPG. Some go as far to say "the 4th entry proved to be not only one of the greatest Genesis RPGs of all-time, but one of the greatest RPGs period."
