This is the Game Boy Advance software "Toyrobo Force." It's a shooting game where you customize robots by combining parts and then battle. This is a used item, purchased new and played a few times, but I believe the quality is not particularly problematic. I have confirmed that it works on a Game Boy Advance console. This is a software-only listing. The box and instruction manual are not included. I will wrap it in cushioning material and ship it via anonymous Mercari delivery.
