This is an odd one so I will describe it the best I can. This is a prototype copy given to employees to test the game before it was released. This is usually to look for bugs in the game at this point in development. The disc is an actual GD-ROM and not a burned copy. There is no artwork on either side of the disc. The title is written on the top of the disc so you know which side is up. I tested the disc in a regular Dreamcast console and it worked like normal, though I am not sure if there are any bugs in this version. I also made a custom case with artwork to house this disc properly. See all pictures for details and if you have any questions, please don’t hesitate to ask.
