Snes woes, restart loop, corrupted graphics

Hi guys I know absolutely nothing about repairing super nintendo consoles and wanted to know if you know from your experiences what component(s) could be causing my original brick North America SNES to be in a restart loop in most games I try to play.

The only game I own that can get to play without error is Incredible Crash Dummies.

If I try to play Final Fantasy 6, the game works, but the tile sets are completely messed up. For example, instead of Locke on the world map, my character is Emperor Gestahl. When I walk into a town everything looks like there was a glitch in the matrix.

The main menu of Populous boots up, but the second I choose to start the game, it restarts.
Lufia 2 restarts.
SimCity looks like it's going to boot up, then restarts.
Lagoon restarts.
Super Mario RPG restarts.
Kirby Super Star restarts.

All these games restart repeatedly until I turn the system off.

My super gameboy works flawlessly. I can play any gameboy game I attach to that.

I had my snes in my closet for years until I tried playing it again, and it was in working condition the last time I played it. So all I could logically think is something corroded, even though it was stored in an air tight container.

I tried gently cleaning the pins of both cartridges and the console, no difference. I tried using a game genie as a proxy cartridge and it still made no difference, though the game genie itself loads up. If I look inside my cartridge slot, no pins look bent or out of shape.

Can anyone please shed any light on my issue? Thanks in advance.

 

Sounds like there's something wrong with a motherboard component. My guess would be the CPU as the Super Game Boy contains its own CPU for processing gameboy games.

Perhaps you could look at the motherboard or take a picture of both sides and post it here.

 

Maybe VRAM or signal encoder?
