Stopped by a yard sale last weekend and picked up a PSP along with a few games for cheap. Never was into PlayStation stuff as a kid, so I’ve got a whole new handheld library opened up with this new system.

The next day, decided to try my luck at a local flea market. I found a couple dollar games, but also found a GameBoy. Quite a bit of discoloration on it, but I didn’t buy it for the system.

Inside was a curious little cartridge.

After doing some research, it seems to be a flashcard Nintendo used to test out various games. They were able to rewrite games to it with proprietary hardware they had. This one’s got a silly M&M’s game on it, but for what it represents I’m very excited to add this to my collection!
