I already had it downloaded on my computer before, but I deleted it because I needed more room because school started, it didnt crash or anything it worked perfectly, but it was a blue window with a little bit of green, and you needed a connection to internet to use it and it had almost every single game on there, you could choose to play a SNES (you had to buy that), Genesis (you play free with download) and NES (same for Genesis) and I think Gameboy..anyone know what its called?
