So far my results are inconclusive. I'm seeing the TLCS900h read 00 00 for 4000h and 4001h (I had some reading out of order), and now my Z80 is reading 01 0E for 4000h and 4001h. Next step is adding in the Z80 debugger to NeoGPC, then I can figure out what the Z80 driver is writing that allows the TLCS900h read to pick up on. I'm also trying to conceptualize on how to run the two CPUs side by side that does not rely on the tlcs900h.cpp code doing sound executes (driving a cycle forward), but that might be a little too complex for this experiment.
