    Hi everyone, I'm having some issues programming GALs with my TL866, namely the 11D IC (BPRG1) on SF2: CE.

    Hi everyone, my Nanao MS9-29A is having what I've deemed to be a sync issue. Here's a video. I originally thought it could be 60hz interference; however, I now think it is sync as different game boards yield different results. The Sega Touring Car manual that specifies to scope TP1 for the...
