The Dreamcast CHECK-GD
Description
Dreamcast Check-GD is a piece of software for the Sega Dreamcast contained in a specially labelled GD-ROM disc used by Sega to test the Dreamcast hardware. It runs a diagnostic check on the system and identifies any problems with the console it's running on.
The Check-GD comes in two parts:
CHECK-GD and adaptor, property of Adam Koralik.
The Check-GD tests all aspects of the hardware, curiously using art from Sonic Jam and music from the Japanese version of Sonic CD while doing so.
Check-GDs were not sold to the general public, and were unlikely to be used outside of Sega's testing facilities.
Versions
There's several versions of this disc floating around. On the old assemblergames forums somebody tried to make a list of them but it was not accurate.
Here's what I could come up with based on actual photos and dumps of the different revisions:

The Check-GD comes in two parts:
- A disc, which is placed inside of the Dreamcast console to run the diagonostics (this disc contains all the code).
- An adaptor, which plugs into the Dreamcast's serial port to check its functionality. The disc will fail the SCIF test if the adaptor is not connected.

Questions
- What's the difference between 'DC checker for MP' and 'DC checker for REPAIR'?
- Were there any CHECK-GDs also used in any SEGA office in Europe?
- Are there any other versions of this disc?
