Curiosity got the better of me and I played this game. Besides being a cute Galaga spinoff, I didn't really have any problems playing. I used DOS MAME36 Final and no sound, and in my monitoring I found no slowdown at all during the game. In fact, I had horsies to spare.(posted 9242 days ago)If you're having trouble with a slow game, I'd suggest using an earlier version of MAME or turning sound off. Frameskip shouldn't be necessary with the setup you describe (I have a 700 MHz Athlon, 96 megs of RAM).
