No.16721 Osso Moderator Aug 5, 2019, 07:12	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.
No.16736 hackbar Tester Aug 10, 2019, 02:40	Can someone assign this to me? My account doesn't seem to have the right privileges.
No.16755 hackbar Tester Aug 15, 2019, 00:37	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?
