i did this mod a few years back that might be interesting to some.i took a nes joypad and made it work for my c64,atari st,amiga 500 or other atari compatable.i won't give details on how to do it now but i did save the paper telling me how somewhere.if anybody is interested i suppose i could dig it up.the mod used one of the buttons for fire and the other as an extra up function.this is useful for those old games that use up as the jump in many games.instead of using the directional pad UP to jump you just press the 2nd nes button.i remember the mod wasn't that hard to do and was very worth it because i was getting tired of using stick style atari controllers.this also makes the games more enjoyable and easier to master.
sound interesting?
