This is a used, working 1MB expansion RAM cartridge for the Sega Saturn, with some damage to the case. It is required to play certain games (such as King of Fighters '96). KOF96 was used to confirm operation. (The product is only the expansion RAM, the software is not included) You may be concerned about the masking tape, but this product is very unstable in operation, and it was designed to only work if it wasn't fully inserted. There were various methods for starting it, such as intuition, marking with a magic marker, or the "postcard method," but I use masking tape as a guide. As shown in photo 3, when viewed from the front, it seems to start up more easily if you adjust the line under the masking tape to be just barely inside the console. (There may be variations depending on the Sega Saturn, so if it doesn't start, please adjust it yourself.) * The tape can be easily removed. * Because it is originally unstable in operation, returns due to unstable operation will not be accepted, so please be aware.
