★Important Notes★ Both of these game cartridges worked and played on my Game Boy, but if they don't start up properly on your device, please try inserting and removing them a few times. You might have better luck inserting the cartridge firmly. This is a set of two Chibi Maruko-chan Game Boy games. I have confirmed that they both start up. I've also included photos of the startup screens. - Game Title: Chibi Maruko-chan Okodukai Daisakusen (Chibi Maruko-chan's Allowance Strategy) - Game Title: Chibi Maruko-chan 2 Deluxe Maruko World - Country of Manufacture: Japan - Compatible Systems: Game Boy Color Thank you for looking.
