I've got four pre-release Dreamcast games on Sega GD-R discs. These were provided prior to the release of the Dreamcast for magazine reviews. I've also got a Dreamcast System Disc 2 Sega GD-R.
The top left disc in the image is "Redline Racer." The version is labelled "E3," and dated 7/5/99. The disc says that it's #10 of 10. Criterion Studios.
The bottom left is "Tony Hawk," version 4.18 and dated 3/25/99. By Crave.
Middle bottom is "TrickStyle," version 004, dated 8/3/99.
Top middle is "Sega Bass Fishing," dated 6/17/99.
I would prefer to sell these together. I've yet to come up with a price, but I'm interested in serious offers. Thanks!
