Update:
Added the archive of all dumps (in CUE format) for the 13 prototypes of the In Utero tribute project. This is for preservation, to play the game, choose the GDI or the CDI.
2 out of 7 discs could be saved for Jekyll and Hyde Dreamcast (Unreleased):

The various attempts to dump the 4 Evil Twin discs represent 18 GB. The various attempts to dump the 7 Jekyll discs is also 18 GB.
There was also an early version of Millenium Racer (about 5 months before the 2017 release). We could not save the GD-R:

The discs that don't work are bad burns
One of the Jekyll and Hyde prototypes that I couldn't dump dates back to February 2001, 3 months after the last one that is playable. The game may be complete!
One of the Evil Twin prototypes is from an E3 build, the first time the game was shown to the public. This prototype version dates from 17 months before the final version. We will still test to be able to dumps it without data corruption.
