Bandai's WonderSwan software "Ten no En na Dungeon", operation confirmed. - Model: SWJ-BAN002 - Brand: Bandai - Game Title: Ten no En na Dungeon - Compatible Models: WonderSwan - Operation Check: Operation Confirmed Thank you for viewing. I sell a lot of retro games. I used to run a game shop until 20 years ago. I have been storing the inventory in a dark place, and it is kept in a relatively clean condition. This time, I have selected items with less deterioration and am listing them for sale. [Game cartridge only] Although it is a product from about 30 years ago, it works without any problems. I have confirmed that the software starts up on my own game console. I cannot guarantee the remaining battery life. The cartridge terminals have been cleaned. There may be compatibility issues with the console. Please insert it firmly each time without giving up. Even without terminal restoration agent, you can make it easier to read by rubbing the terminals with a cotton swab with Magic Clean, etc., and wiping them with a dry cotton swab. Please try it. Welcome to combine with other software ♥ Please be sure to contact me before purchasing. I will discount 100-200 yen for each additional item ♥ When shipping, I will wrap it in cellophane to protect it from rain, etc., and reinforce it with bubble wrap or cardboard for sturdy packaging to prevent crushing.
