I haven't used my sd2snes (rev f) in a few years, and now today trying to boot now shows black screen. No other snes to test sd2snes. I see verified seller no longer affiliated :( Diagnostic results:

It seems like it's your SNES that went bad though.

The snes still plays normal games: SMW, Zelda, Super Mario Kart, etc. I think I need another snes to test with to know if mine is half/dead... Unless there's some other way to confirm?

PA is one of the outer pins not used by most games. Clean the cartridge slot.

Ok I cleaned both of the side slots and that made no difference. I also looked over some basic cleaning/maintenance guides and there is a slight possibility I reversed the cartridge slot (I forgot to mark front/back). However I had this issue before I opened up the SNES to check for bad caps, corrosion, and broken traces.

Same situation as before cleaning: my retail games work but SD2SNES won't boot anymore. Continuing my search for a replacement SNES, and also looking out for an Analogue Super NT to come into stock...
