I've only used an N64 emulator once, and it worked fine for Conker's Bad Fur Day. I was playing with the keyboard though. If I want to play anything emulated I use my hacked Wii. You can use it for all sorts of things when it's been modded. I have emulators on therea filemanager, a program that lets you play Wii ISOs installed on USB that you've downloaded or that it rips from games inserted in the Wii. A media player/server that plays DVDs and a crapload of other video formats.
I type the rest later POS Crapatalk is glitching out again.
