Thank you for viewing the product description. ● About the product This listing is for 10 game cartridges only. The game software has been tested on a Game Boy Advance SP and confirmed to reach the initial screen! Rockman EXE 4 Red Sun was difficult to start. I confirmed that it starts without problems if inserted with a slight (about 1mm) lift. The battery life has not been checked. Please purchase only if you understand this. The exterior has been cleaned, and the terminal metal parts have been cleaned with distilled water and contact cleaner. Please check the photos. ● About packaging The cartridges will be placed in mini zip bags, wrapped in cushioning material, and shipped.
