if anyone wants it, there is a very handy dc controller test program over at dcemulation (or email me if you want) you burn it to a cd and put the cd in the dc, when it starts up its a pic of 2 dc controllers, when buttons are hit or directions pressed, they show on the screen, kinda helpful for testing connectiosn fast. i was having an analog problem that i couldnt find until i used this, one was stuck and it was screwwing everything else up. i begged and pleaded with the dc emulation gurus to help me and they did!
for trouble shooting controllers it is good to plug one that works into the others to test that the ports work. i have done quite a few dc hacks and have ruined a few too, they are touchy SOBs.
