Well that is a "ehhhhhh" emulator system. I can play TIT without glitches on my computer, the retro consoles i dont like because the 3 in one (Genesis, NES and SNES) console they made after that makes it so you cant slide down hills in SMB 3 like on a NES or computer emulator. Its effy but can play other games fine and some others not fine.

Theyre coming out with a 5th one and it looks bad ass, hopefully now theyve perfected the emulation and itll be a great machine. But the ones that are out now I dont like, but theres hope.
