I just bought a used copy of the Super Scope 6-in-1 cartridge, and it looks absolutely pristine. There's not a scratch on the front or back labels, and I took a magnifying glass to the contacts and could not find a trace of dirt, or a hair, or anything. It looks like it was played once and then never played again.
I just put it into my SNES, which has never had a problem whatsoever since I had it from all the way back to Christmas '92, and the last time I played it was a few days ago. Perhaps a week and a half ago at the most.
I put in the 6-in-1 cartridge and turn it on. I get a garbled screen of what I know is supposed to be the part where "Super NES Super Scope 6" reverse-zooms in on the screen. I turn it off, eject, and clean it the cartridge. I try again. I still get the same garbled screen.
Thinking the game is just defective, I put in the game I last played (Metal Combat: Falcon's Revenge). NOW IT IS GARBLED AS WELL!
I immediately take the official SNES cleaning kit (yeah, I have one of those) and begin quickly using it on the console. I try again with Metal Combat: STILL GARBLED!
It is also the same garbling every time. For example, with Metal Combat, what I know is supposed to be just the Nintendo logo as soon as you turn it on is now a crazy maze of white and black of the same garbled sprite repeated. And it's always this with each time I try to turn it on.
The game plays like nothing is wrong. The sound is fine as well. It's just the screen is garbled like nothing I've ever seen before.
WHAT THE HELL JUST HAPPENED AND HOW CAN I FIX IT?!
