I started working with your VS DualSystem NES 2.0 files. I setup 2 CPUs bridged by the shared memory range. And I am alternating between executing one instruction each processor. The master CPU appears to be attempting to trigger interrupts on the slave processor and I see reads from the exact addresses listed in your stub-processor code snippet. But the slave processor appears to be stuck in an infinite loop. It's not interested in the interrupt requests.NewRisingSun wrote:Of course. Just look at the Vs. System's ROM files...
I'm not sure what I'm missing here. Any suggestions or experiments I can try?
