yeah only citra 3ds can run it their are unofficial chinese builds (cant link for some reason i think because the unofficial uses copyrighted Nintendo code to improve speed where as the official ones stay in a grey area using their own code and no propriatary code) iirc it's cause your computer has access to alot more resources (RAM for instance) then actual hardware meaning some mods can be used on roms that the real thing can't handle also the reason why some mods for say Skyrim will work for the PC but not a hacked PS3/360
