Yeah, I picked of one of these with it's two Japanese import DDR titles for £25 the other day. The DDR games aren't really to my taste, but Space Channel 5 works remarkably well with it (seriously, the game is ten times better with the mat.)

I tried other games that use just the d-pad, A and B, but most of them naturally didn't play well on it. Could anyone recommend any titles that would work nicely for it, excluding Feet of Fury?

Games I had a go at (with not very sucessful results):
Virtua Tennis
Mr.Driller
Ready 2 Rumble
International Track and Field
Bust a Move 4
Sega Tetris
