I think you ment to say:
BCALL _GrBufCpy
At least I guess that this routine will produce better on 15MHz...
I could also use the older greyscale routine used by the z88dk, which
doesn't use the fastcopy, and replace there the own LCD_BUSY with:
PUSH AF
CALL LCD_BUSY_QUICK ; $000B
POP AF

Okay, that's something I should have thought of...
The *same* trouble with the CrASH's CR_KHAND routine (Ti82), which will
copy your program back into it's variable...
I have already some App crt0 made, but haven't tried if it worked (Need
Flash debugger first).
