Guess I should have asked this a long time ago.
Im actually running R6bc002 FW on R1JG00X FS and it seems to work just fine..
Has anyone tried it?
So I decided to try this just for fun and it works just fine....
Running R8BC004 FW on R1JG001 FS (went with R8BC004 cuz there was a patch that I wanted)...
No problems so far!
