Got the NES Everdrive in today. Its really a nice piece! Its nice being able to play the disk system games, and it auto switches disk A or B for you, really a nice touch. So far I've been very impressed with these chips. I've got the Turbo one, Snes , and now the NES. Think I'll grab the N64 one next. I may get the MegaDrive one at some point, not sure yet.
