[quote name='QiG']I had a lot of trouble playing Bust a Groove on my PS3, beyond the fact that I suck, I blame it on the bluetooth/tv response time lag. Maybe they don't transition well?[/quote]
It's not that (despite what TMK says). Bluetooth/TV has nothing to do with it. The rhythm is just off in Bust a Groove. You can confirm this by going in the options menu. You can watch the game go off beat all by itself. It's actually worse than a delay/lag because you could compensate for that (if you were crazy/determined enough). But the rhythm shifts in and out of phase, making the game impossible to play. It's an emulation or audio/video sync issue that has never been fixed.
I've heard that the PSP Parappa is harder to play than the original and that it seems off rhythm-wise, too. I have a clearance copy that I haven't played yet.
