I believe it is simply playing the games in Coinops+, noting how well they play, how good the keymapping is, if sound works, etc, and suggesting fixes for things like keymapping. Pretty simple task, disappointing it has gone so slow. I for one am starting to chip in right away. How hard a task is it to play games? Oh - and put me down as one who would kill a man in front of his own mama for working sound/speed in midway games. The original Mamex seemed to handle this a lot better, not sure what has been lost in the new ports?
