SNES

CPU (SNES)

1min

The SNES CPU has many revisions of CPU, often labelled CPU-A, CPU-B and so on.

You can interchange all 2-chip CPU's as far as I have tested (although I haven't tested a 1-chip CPU on a 2-chip.

Fault Symptoms

Below are a list of known symptoms I have discovered when repairing that are from a dead CPU.

  • Super Gameboy won't load or shows glitched graphics
  • Donkey Kong loads initial logo then black screen
  • Super Ghouls & Ghosts loads CAPCOM logo, then black screen but audio works
