Does anyone know if a part exists for the RP2A03 out of an NES?
Have you got a link.
Doesn’t look like it (nor a 6502). A generic 40 pin IC with the pin numbers from
would likely be your best choice as there also doesn’t appear to be a datasheet.
Just grab a generic IC from CORE bin, change it to 40pin in Inspector, and then change the pin spacing to match. You can right-click EDIT and change pin names in Connectors and info in META and save as a custom part, if you want to go to all that trouble.
Okay, thanks a lot! I’ll try that.
