A community for discussing all things PlayStation.
The instance rules apply here alongside two community specific rules.
Rule 1. Please keep all discussion relevant to PlayStation consoles, games and services.
Rule 2. Lemmy.zip allows NSFW content but I’d rather keep this a safe community for gamers of all ages so please don’t post adult content here.
That’s it for the rules.

Does anyone here know a lot about PlayStation 1 mod chips?
I took my old PS1 apart and found the mod chip that was installed back then.
The PS1 has a PU-22 motherboard, and a PIC12C508/P is soldered onto it. The chip is glued into the case and soldered to the motherboard with wires.
If I’ve identified the pins correctly, pins 2, 3, and 5 are not in use.
I’m trying to figure out exactly which firmware or mod this might be.
I would never need this in my life but I find it really comforting that things like this are archived and shared and rewritten decades after they’re relevant.
