Added relationship. I did notice kram also has issues with start buttons at least, sdungeon seemed fine.

Adding 'm_pia0->set_port_a_input_overrides_output_mask(0xff);' fixes the problem, but I think that a review from the author of the patchs is needed.

Can someone assign this to me? My account doesn't seem to have the right privileges.

Looking at the schematics, it seems the mapping of buttons to PIAs is just wrong. I don't have the system to test on though, and the manual doesn't say what the switch test numbers mean.

Anyone got a real board?
