SNES hardware problem?

My room mate just brought up his old SNES. It's pretty old, pretty beat.

Anyway, It seems to work fine, but when I put in the SuperMarioWorld cart it boots up, it works, but yoshi's tongue doesn't move forward. Autoscroll levels don't scroll. The rotating platforms don't have any connecting balls.

I'm thinking it's the chip that controls scaling and rotation, but I don't konw for sure. Has anyone ever heard about this or know of a way to fix it?

It's not the cart, either. He has two SMW carts and both produce exactly the same result.

Pictures/video can be posted of it upon request.

must be some problem with the system, maybe the slot were you insert the game is dirty.

Open it up give it a good cleaning. if it continues then I'd say something is busted.

They're like $20 to replace

I don't know what would cause this kind of weirdness without breaking something more obvious (e.g. corrupting sprites), and I can't make any sense out of the only SNES schematic I found, so I don't know what to tell you. My best guess would be to check the PPU chips (I don't know the P/N but I think they are marked "PPU1" and "PPU2" either on the board or on the chip packages themselves) for broken solder joints.

Wow. this thread sure got revived.

I figured it could be one of the processing units. I'll look into the solder joints.
