SKR as in SkidRow? What is your adf source? Probably one with an old TOSEC set because I believe the recent ones use SR for SkidRow.
The three [cr SR] disks are available on the EAB file server:

under the path:
/Commodore_Amiga/TOSEC/Games/[ADF]/G-Q
Your explanation does not really make sense, at least from a logical point of view
