So, here's how it went down.
Hooked up the SNES, using RF Switch, everything works, almost.
Sound is great, controls are great, picture sucks. The screen itself is hidden behind a wall of scrambled sprites. I can see the characters moving, but nothing is defined enough to actually play the game.
I toyed with the idea that I might be using the wrong channel, but I figure nothing at all would show if I was.
I cleaned the hell out of the system and the games. The problem is the same for each game, so I'm guessing the problem lies with the system.
I haven't tried connecting with a RGB wire or anything else for that matter.
Ideas?
