I wanted to mod an old game system, and I’d like to use the earlier digital-only PSX controller. I’d like to know what is needed to make Arduino read PSX controller data and output 9 different digital uttons in the form of up, down, left, right, 4 main buttons, and start button. L and R button is not needed. Analog controls will also be ignored since it’s not supported on my console.
I’m planning to add PSX controller port on my Atari Lynx, wire the output directly to the Lynx’ direction, A, B, option 1, 2, and pause. The button are floating high when not pressed, and 0v when pressed so the output from Arduino would need to be coded to have digital output go low when PSX controller’s button or direction is pressed, otherwise hold high.
I’m doing this mod in conjunction to Lynx to TV mod that someone posted on Atariage forum, being able to play Lynx games on big screen and using lighter, more comfortable controller would help me a lot.
