Hiya, well, it looks like it's causing trouble for me, too. Currently I don't get any video signal, not even the score display. The 9602 emulation also seems to be very broken, because neither stars nor the vertical line at 256H appear.

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...
