Awesome, thanks a bunch.

I also have a SCPH 1001 model I'd love to try it out in as well if you have any diagram for that one.

Ahhhh, the github had seemed to be mentioning ATTINY45.

I went ahead and ordered some of these:

I am interested in testing this out on some PSOne NTSC - USA.
Is there a diagram for it? Is the github not the latest version to write?

Are there install diagrams for these?
I'd love to test this with some ATTINY45-20PU.
