Latest prototype PCBs arrived

Latest prototype PCBs arrived

Quick update, the latest prototype PCBs arrived a couple of days ago. Assembly is in progress. This revision reduces audio noise from the DAC. This was a problem with 1CHIP SNESes which introduce much more noise, presumably due to their much steeper signal edges on the bus. The noise disappears when using a “custom chip game” case with the additional grounding prongs. I didn’t want to rely on that though, hence the hardware update. ;)

Here they are. I hope this is the last hardware revision, all those prototype PCBs are getting expensive…
