This is a set of 8 demo discs from the US Official Dreamcast Magazine. These will not work on a Japanese Dreamcast. To play import discs, you will need either a US Dreamcast or to modify your console. Each item is 500 yen. If you only want to purchase part of the set, please comment at the time of listing and we can accommodate. Please note that I have not personally tested these. The discs have only a few scratches and appear to be in very good condition. #sega #セガ #dreamcast #magazine #demo #disk #disc
