OK, follow-up.
It's not the panacea I thought it was. I seem to be able to make some games play at full speed (or even way too fast), such as Pac-Man and Ms. Pac-Man. (I know, I know... I just chose Pac-Man for testing purposes.) But I can only do that through a mystical voodoo combination of switching between software rendering and OpenGL rendering as well as toggling fullscreen mode. (It only plays at the proper speed in fullscreen... and in fact Ms. Pac-Man plays like a speed chip modded arcade machine if I turn off speed limiter.)
However... Activision games (I tested my two favorites, H.E.R.O. and Keystone Kapers) seem to have trouble working at all in fullscreen mode... video, anyway... and when I switch back to regular mode they are EXCRUCIATINGLY slow. What's worse, if I fire up Pac-Man or Ms. Pac-Man after that, they're slow too! I have to restart the program to get them fast again. Also, it's kind of spotty in remembering my preferences, including OpenGL rendering mode, screen mode, the last used directory (jumping back to the default ~/Documents which is NEVER where I keep my ROMs!), etc.
Granted, even with these glitches, I will probably use this version more than the last, since I had to run it in a microscopic window to get my G3 iBook to play at full speed.
