The cartridge arrived spotless, no grime in the pins at all, and it fired up on the first try. Tested it for an hour and it never froze once.

The cartridge was cleaned so well it booted on the first try, no blowing required. Spent a good hour on it last night and the save function held up fine. Exactly what I hoped for from a tested Game Boy game.

Popped this in and it fired right up, no blowing on the cartridge needed. The label's a little worn but the pins were clearly cleaned well since it saved my progress fine. Been playing through the co-op with my kid and it holds up.
