I actually had scheduled yesterday as the release date for the beta Popeye core but I got stuck with a problem in the DMA circuit. I thought it would be nice to be able to simulate the schematics directly without having to convert them to text myself. I usually just read them without simulating anything but this time I was a bit confused.

I started copying some schematics to KiCAD, and then wrote a file conversion program to process KiCAD's output into something I could simulate. This is a new work flow I didn't have before: drawing new schematics from old paper schematics and simulating.

This makes the simulation work easier and it also opens up the door in case someone wants to build a new Popeye PCB. Indeed, once schematics are drawn someone may come and lay out the PCB and manufacture new Popeye boards!

Anyway, I already fixed a bug thanks to this. I am trying to finish up to release the beta. Patreon still has not provided me with the final list of patrons for this core but it should come soon too.

The schematic on the screen corresponds to page 3 of the video section of the Popeye manual.

The Popeye PCB is not compatible with other game / rom?

Very cool. Can you share the tooling on GitHub? I would love to try that on some old Atari schematics.

Awesome! Would be nice to make a "new" jamma standard pcb for some of the old titles. :D
