Sweet Ange GB game software. Includes cartridge and instruction manual! Startup confirmed. Please note that we do not know the remaining battery life of the internal battery. Also, this is an auction for the cartridge itself, without the outer box or case. Please understand this before purchasing. The cartridge has scratches and stains. I was able to confirm the operation up to the OP screen on my own device. The instruction manual has tears, damage, and stains. This is for those who are okay with being able to read the contents. It may be difficult to start up depending on the compatibility of the device and the environment. We cannot guarantee certain operation, so please consider it as a guideline for startup. Due to the age and the fact that it is a used item, please refrain from purchasing if you are sensitive to such things. Thank you for your understanding and purchase. To prevent trouble, we do not accept returns, so thank you for your understanding.
