THIS! Yours was the site I was trying to find earlier; I suppose I just massively overlooked it in google. Sorry about that.
For me, the only reason I didn't replace the switch altogether was that my hands are very shaky as it is, so shorting it out was the only thing I felt comfortable doing; hardware stuff gets to be too challenging for me sometimes, especially when dealing with intricate little plastic pieces.
And while on the topic of X'EYEs, might you know what would cause the system to slow down constantly (i.e. whenever a game is being played)? Mine's been having trouble with slowing down during CD games, and Genesis games are just crap to play, altogether. Sonic 3 plays like I have a slow-motion switch on, as does just about every other game. Further, when playing Genesis games, I get no sound; sound does, however, work when the music is coming off of the CD, like if I play the CD player or listen to music while playing a CD game. I've ben told it's a capacitor issue, but I have no real clue. Thoughts?
