I guess I'm going to have to get better at comando if ya plan to speed it up! :P.

What are your plans for the games that you don't make part of the official release? Will you release more versions of MAMEBoyX with whatever optimizations you make or is it matter of holding on to this version if we want to play those games? I'm afraid that I can't give up asteroids. There are others I'd miss but the two asteroids games would be the only ones that would make me keep two versions of MAMEBoy on my machine :).

Anyway, thanks so much for your efforts! There is no better Mame for us E-125 (and other casio I'm sure) users!
