DOes that have something to do with the game rom not working from memory?
Not 100% sure as yet. I'm chasing my tail a bit as problems are somewhat intermittant. For example, this morning, IRQ was stuck LOW and had funny displays on screens.
Tonight, IRQ is getting stuck HIGH.
According to Clay's guide, it may be issues with U2/U3 game ROMs.
I'm hoping for someone who may be able to guide me in this area.
Reset
appears to be functioning correctly, I've replaced crystal and Z2 & Z3 just to be sure. U4 & U5 also changed. U1, U4, U5 & U6 all appear to be getting clock signal too.
