I've just had a go on Waverace 64, Ridge Racer 64 and Mario 64 and they run very well with some of the main objects or characters a lot sharper.

The controls are also easier than say, the Snes, as the stick is more user friendly although the friction on my fingers can get a bit much after extended use!

I've also got a few more games to try out yet.

I may be some time...
