MAMED again

Dunno why but since switching to a Macintosh again I just never really thought about the joys of MAME. This weekend the talk about XBLA and some of the footage of upcoming classics from E3 made me think. And search. And lo, it does exist on Mac, and with the startlingly original title of MacMAME! So now I once again have my Paanacea of arcade games, Mr. Do! at my disposal. To be honest there are very very few games from that era that really stand examination today, so Ill never be a collector.
Ill also go on record as stating that Ill happily pay for these same games on my 360 if and when XBLA gets them. In fact if there was some way of paying for the ones I have Id happily do that.
So lets hear it for Mr. Do!, Time Pilot, Gyruss and Salamander!
Now I just have to find a decent controller. I bought one USB pad from PC World this weekend, but it still sticks on the directions. . I think because these original games were so simple they cant handle two direction inputs like can happen easily when running a thumb over a pad to change directions. So the game sticks or the irrepressible Mr. Do! goes off in exactly the wrong direction. Any hints/tips/help welcome!
BTW, Mario Kart DS fucking rocks, and I cannot fucking wait for Wii!
