Idea for Multi-Button Controllers and the Atari 8-bit and ST/TT/Falcon

[pixelmischief]

Here's the idea: I start with a 3-button Genesis controller. I build an dongle that intercepts the controller signal and converts buttons B and C to the "impossible" directional pad combinations UP&DOWN and LEFT&RIGHT. I write some little code that PEEKS the port and see what value is presented when those buttons are hit. Then I patch games that have both jump and fire, and use up for jump (we hates iiiit!) to use the additional button(s).

 

What say you?
