Which one of the 7805s is the one to the SNES part of the board?
I only have one extra 7805 and both of the 7805's have fried (I think) from an accidental placement of the batteries backwards.

For my portable, I am using a PSOne screen. One of the regulators broke, so both are connected to each other in parallel. I also am running a SNES and seperate audio amp off of it, and The PSOne screen's thin sheet of copper and a piece of cardboard with 22 gauge wire threaded through it is plenty to keep to heat at bay.
Hey, sup?

Your right I don't know if its the 7805's that fried but since I didn't hear anything snap crackle or pop, I thought replacing them would be a good place to start.

Well if the SNES is not working... quote me if I'm wrong but that little black guy close to power labelled 1.5A is a 1.5A fuse?
Just remember the heatsink used in SNES revision 1 for the regulator was seriously a casing covering half the board...

You say it can't be done. I'll damn well show you it can...
Just may not be cheap. Or practical.
