I'm going to exchange a little secret... on mame.retrogames.com, they actually do have archives of earlier betas! They're hidden however, but can easily be found - I think the file is m36b7b.zip or something like that. Replace the b7 with b1 or b2(i.e. m36b2b.zip) in the location URL, and bang you've got the files! Be aware though, when you unzip the file, be careful you don't overwrite your newer MAME executable.(posted 9181 days ago)
