---- ... or if it was due to inaccuracies with the simulation - I was using unit gate delay, so every single chip had the exact same delay, which was accurate enough for Pong, but probably not accurate enough for the more complex games. What kind of method are you using for the gate delays? I always planned on starting over from scratch with a more accurate... -------

I have the different delays for the 0->1 and 1->0 transitions from a TTL data book. Most delays are for the SN74xxx types, i.e. the earliest chips, except when there are only 74LSxxx or other newer types.

Pong runs at roughly 4 fps on my Phenom X4 2.3GHz. It of course runs on one CPU only, and I'm thinking about ways to distribute the work load across multiple cores...
