Very cool game! Graphics are top notch; I've never seen anything like this. Definitely worth the money. Keep up the great work!
One problem I had with the sound: I can't seem to find the right settings to get good speech with the Ultimate 64 and an original 6581r3 inside. Sounds great on a stock 64 (with the same SID) and a 64c. I've disabled the addressing for the UltiSids and seem to only have the socket with the 6581 enabled, but the speech still stinks (drowned out by static noise kinda). It does sound different than the UltiSid though, so I figure something else has to be off. If anyone knows good settings for this I'd love to know.
