Well I think this might actually be my replacement PC Engine PCB working first time, or at least one of the video channels looks plausible on an oscilloscope and I'm pretty amazed I've not had to fix anything to get to that stage

This is the PC Engine I impulse bought in Japan, which then never worked, probably first because the ribbon cable was fragile and had broken, and then because of all the damage I'd done when reworking the PCB (I hate old PCBs), despite my best efforts to check for broken traces. The next step is to move over the 69-pin rear connector, which is not a desoldering job I'm looking forward to

The PCB was ordered from JLCPCB using https://github.com/Board-Folk/PC-Engine

Nope! My TV doesn't like what my OSSC is putting out, and my OSSC is reporting the refresh rate fluctuating a fair bit. The working PCE I have is sitting solidly at 59.98Hz
Oh hey, making sure all the surface mount passives on the bottom were properly attached is all I needed for success! Now just to test its controller input, and also fix the cartridge slot
And the cart slot PCB is repaired with a few wires between the RAM chip and the connector. Now to just wait for the other bits I need to fully assemble it to turn up somewhere...
