I used to have one of those - I guess I must've sold it though as I can't remember what happened to it!
I haven't a good thing said about Buy Rite though so I'd be a little wary.
I think the CD32 is rarer in some places than others - I noticed some bidding going quite high on Ebay the other day and questions coming in from Germany and Australia etc. I quite like the system myself.
Rarest stuff I have would be the Sega Multimega and Neo Geo AES I guess.
Apparently the unofficial maracas will only work with the original Samba de Amigo and not 2000, but I never got around to trying 2000 before I sold it.
Actually, there was no readme file with the 133 and 166 versions I downloaded so I was rather stumped myself. I then assumed it would use the same as FGen so I checked the readme that came with that.
Certainly don't consider buying a Super Vision for playing the games. I had a Quickshot Super Vision and it's probably the worst console I've ever owned. It plays more like the cheap and nasty Radica handhelds than a Game Boy. Mine got sold pretty quickly and pretty cheaply!
Well the links open in a new window - have you got a pop-up blocker that's preventing the links from working as I've just tried a handful and they worked ok.
