Loop Checker version 1.00 N0 SDPS-1

A GD-R which was to be used by after-sales services. It allows you to analyze in detail the components of the dreamcast in order to detect problems.

You can download it below:

Loop Checker version 1.00 No.SDPS-1

DC.checker for REPAIR version 2.15R No SDPS-3

A GD-R which was to be used by after-sales services. It allows you to analyze in detail the components of the dreamcast in order to detect problems. It seems to me less thorough than the "Loop Checker".

Work in progress (impossible to dump it for the moment, I can give a bad dump on request)

DC.checker for REPAIR Silver version 2.05

A GD-R which was to be used by after-sales services. It allows you to analyze in detail the components of the dreamcast in order to detect problems. The version is older than the "checker for repair" just above.

You can download it below (thanks to Darcagn who had dumped one of those I had sold)

DC.checker for REPAIR Silver version 2.05

GD Drive Repair Program version 0.1

A GD-R that checked the optimization of builds and games. We do not really know when it should be used either for the prototypes or for the final versions during their machining. Some options seem intended for the SEGA after-sales service.
