I know I should be putting this in a new subject, but I think it's a part two to ITrek's question.
I want to build a cabinet, and I want four people to be able to play, but four joysticks a trackball and all those extra buttons, are going to make the cabinet look bulky, and crowd the people that are playing the majority of one and two player games.
I was thinking of making the actual cabinet two player, with one track ball, but I would like to be able to use Sega Genesis controls for the 3rd and 4th player, this way the controls will be out the way. I would like to go with the Sega controls for two reasons, first it has three buttons and the start and select could be used for the coin and player buttons, also Atari 2600 controllers use the same input, so I can get real retro.
I've opened up my Sega, and there are no wires everything is just soldered. Where can I go to get info on how to 'cleanly' hack into these controls?
Thanks
