This is a set of a Game Boy console and 11 game cartridges that I used to play about 37 years ago. I put batteries in it for the first time in a while and turned it on, and it worked normally and I was able to play. I will also include 4 new AA batteries, so you can play right away. The LCD screen is slightly discolored with a faint black stain. See image 10. I will also include the adapter, but it didn't work, so please consider it as junk. It has been stored at home for a long time, so dust has gotten into the small crevices. There are also small scratches. I only tested the operation of Rockman World and Metroid, and the other 9 cartridges are unconfirmed, so please consider them as junk. I will ship it quickly, so please rest assured. I will wrap it in bubble wrap and ship it via Rakuraku Mercari. [The following is a common description] This is just the seller's personal opinion.
