I repaired a famicom that had bad videoram chip. The symptoms of this was sprites seemed fine but background was a mess of garbled graphics and numbers and letters. I used the ram chip out of a parts NES board & used a heat gun to easily remove the chip. Works perfect now so if you ever have those symptoms this is most likely the issue. It was actually a famiclone but board layout was identical (older 1989-90 clone) and the ram chips were wider than the NES one but luckily it had the solder spots for the NES narrower ram chip. Hope this helps you or something else in the future.
I’m having an issue with double dragon 2 where the top couple rows of pixels start to appear on the bottom of the screen. They come and go randomly. Doesn’t seem to do it on other games. You think that’s a PPU issue or maybe just my game? I have cleaned the game as clean as it can get.

I have similar problems on a NES console. I was hoping to find a repair video, not a mobo swap. I want to fix, not replace 😓
Dang I was hoping you would swap the PPU! Yeah, it makes less sense as a repair, but for science though!
