MAME, Wii, GC, DS, Xbox 360, PS3, PS2, PS1, GBA, GB+GBC, NES, SNES, Genesis, N64, PSP, Jaguar, 3DO, CD-i, DOS, and Dreamcast. I can't get xqemu to work as of now so no Xbox. I got it to work but it's unusably slow in Windows.
DS, SNES, NES, GB, GBA, Wii, GameCube, Wii U, PS1, PS2, PSP, N64, Sega Saturn, Sega CD, Sega Mega Drive...
Android on bluestacks, emulating snes, and playing kirby's dream land on super game boy. The universe will never be the same.
I emulate windows on my pc, other than that, my 3ds or my wii (soon wiiu) emulates everything else I need.(except for vita)
Nintendo 64, but since my pc's really slow I'd have to close everything else so it runs decently. If I tried emulating a ps4 or something my computer would explode.
