Fixing the Damage of a Botched SNES SuperCIC ModNot what you want to see when testing that ‘repaired’ SNES. (Credit: Skawo, YouTube)The good part about older game consoles like the Super Nintendo is that they have rather rudimentary region locks, but unfortunately this also gives some people the idea that installing something like the SuperCIC mod chip to make a SNES region-free is easy. The patient that arrived on [Skawo]’s surgery table was one such victim, with the patient requiring immediate surgery to remove the botched installation before assessing the damage.Here the good news was that the patient features the revision B CPU, making it a good console to rescue. The bad news was that the pads of the old CIC chip had been ripped up, there was a solder bridge on S-PPU1 between two pins and both the installed wiring and soldering were atrocious, requiring plenty of touch-ups.With the CIC pads already a loss, finishing the SuperCIC mod seemed like a good plan, also since this would make for a nice region-free console. This mod involves a PIC16F630 with special firmware that works with the corresponding CIC IC in each cartridge, while also switching between 50/60 Hz mode to fit the cartridge’s region. After an initial test with PAL and NTSC cartridges everything seemed all right. Then [Skawo] ran the SuperNES Burn-In test from its cartridge, which gave dire news.Something was wrong with one of the VRAM ICs, leading [Skawo] to first try replacing the IC in question with a replacement from a donor board, which unfortunately did not fix the issue. This led him back to the suspicious solder bridge between pins 25 and 26 on S-PPU1. This would have put 5V into a pin that was not expecting it, and may have led to permanent damage.One lifting of a donor S-PPU1 IC and nerve-wrecking swap later, it was time for a retry. This time the test passed with flying colors, allowing Super Mario RPG to be played again without funny graphical artefacts and hopefully fixing the last of the issues caused by the botched SuperCIC installation. Fortunately the damage was fixable, but along with a destroyed case it also took out the S-PPU1, which is not an easy to replace chip.Moral of the story is perhaps that if you really want to mod your SNES, you should leave it to someone who has the requisite skills, lest people like [Skawo] have to rescue another hapless victim from such displays of depravity.youtube.com/embed/L7ZcN4S1QKw?…hackaday.com/2026/02/26/fixing…
