Here's a retro toy I found at home. From the internet: Hudson Soft's "Bomberman" handheld game console (Bandai, released in 1997) Product Name: Handheld Game Bomberman Manufacturer: Bandai (manufactured by Hudson Soft) Features: Two game modes Batteries used: Button batteries (LR44) The exterior is quite deteriorated, and there are noticeable traces of cellophane tape. I haven't confirmed its operation because there are no batteries. I will wrap it in bubble wrap for shipping.
