This post was originally supposed to become a full guide to installing SuperCIC on an SNSP-CPU-1CHIP-01 board using the later F413B lockout chip.

It never got finished.

Rather than leave a one-photo placeholder looking like an installation guide, it is worth recording the important distinction.

The PAL F413B is a later CIC revision and its disable procedure is not identical to the earlier F413 and F413A chips.

In particular, the revision-B arrangement also involves the clock circuitry around U18.

So do not treat an F413A guide as a pin-for-pin installation guide for an F413B board without checking the revision-specific procedure.

I later completed and documented SuperCIC installations on other SNES hardware, but this particular article never became the full 1CHIP-01 guide I had planned.
