hey guys. I have just finished wiring up a controler (re purposing a Mame controller for AES to be specific) and have ran into a bit of a strange problem.
In port 1 all buttons work fine. In port 2 all buttons work fine as well except when i hit select + C for the debug bios menu things start getting strange. Normally in the menu up and down and A + B are to navigate and C to select. That swaps around (a = up, b = down, up = select etc). If i swap the controller for an official controller (that normally works) the problem remains (buttons remapped all over the place) and i have to switch off to get the buttons back to normal. I have a feeling this is something to do with the debug bios not liking directly switched buttons with no circuitry, i tried adding diodes to Select and C buttons but didnt make any difference.
Any ideas? I can just use the controller on port 1 and have another official controller on port 2 for bios menu but it would have been nice to only have to use the one controller
Photos are probably not much help but i've added anyway.
Cheers for any help
