Wow, never thought a specific mode on my SNES would actually fail.. the most spectacular mode that is!
It's not a cartridge thing, as I even went to resoldering the cartridge connector, and yet it's still having this issue. the power supply is fine, i even tried another one just in case.. I'm at a total loss right now... Check out this video (and still images), to see what I mean... the games run fine though...

That's amazing. Time to buy another SNES.
no one knows how to fix it :( i really hate saying this, but can anyone donate an SNES for me? I don't have the money..
if not, i'll just save up for one.. preferably a model 1 SNES, and not those smaller newer ones.. i need S-Video and stereo sound...
Sorry about necro posting on this thread but few days ago I repaired an Super Famicom with the same problem.
I leave an reply to this so people know what is going on with their SNES/SFC with this failure.
Sadly it was the S-PPU1 (5C77) is a 100 pin QFP chip, which requires special equipment for re-working.
where'd you get another one without ruining an already working snes?
I got an non working US SNES (it failed due to mainboard corrosion). I just took the system apart, removed all the important chips, the cartridge connector slot and the sound module and tossed the rest away. Then I used the parts to fix the other two units I had here (one was missing a ton of parts including the top cover and the SFC got it's S-PPU1 replaced. It's working flawlessly now.
