The cartridge contacts looked spotless when it arrived, and it booted without any blowing or wiggling. All the mini-games run fine, and the save feature holds up after a few days of play.

Popped it in and it fired right up first try, no blowing on the cart needed. The label's in good shape and every mini-game runs smooth. Solid pickup for anyone reliving the Game Boy days.

Wasn't expecting the cart to be this clean, honestly. Fired right up with no blowing or wiggle needed, and the save data held fine through a whole afternoon of Manhole.
