Thanks Bock.
But since it's a blogspot it's still not allowed.

What a cool fix! Very creative and I'm glad another SMS didn't have to be sacrificed to scavenge the I/O chip from it. Thanks for sharing your approach.

So you use the same I/O chip, just re-routing some players controls..

Have this issue on one master system 2... never came across a solution that was not replacineg the chip itself.. so.. really good job man...
