SNES: Mario Allstars

Are you using the nes ac adapter with it? I remember some game wouldn't work with it due to power draw.

Looks like there's a problem with the cart PCB.
Some SNES games have screens like that, that might show up because a checksum check didn't turn up correctly or because the game detected too much RAM or just not the right amount of RAM.
This was mean to counter piracy by blocking games from running on copiers and stuff.
In your case it could be for a number of reasons:
1. The connection of the cartridge to the SNES is dirty
2. A/some trace/s on your carts PCB have corroded away
3. One of the pins of the ram chip or the mask roms or a passive component has a cold broken solder joint

Yeah, I believe it's the NES-002 version. But the SNES says that I should use it. And it's the same voltage and what not.

Fuck, if it's the PCB i'm in big trouble. And i'm sure it's that, cause I just cleaned the contacts on a batch of games I just bought, including this one...

Well, I just got it to work. I started another game, turned it off and put in Mario Allstars.
It loads, but when I select a game I get the same screen. Fucking weird
