The CDL file format is right there in the .CHM file.
Code:
xPdcAADC
C = Whether it was accessed as code.
D = Whether it was accessed as data.
AA = Into which ROM bank it was mapped when last accessed:
00 = $8000-$9FFF 01 = $A000-$BFFF
10 = $C000-$DFFF 11 = $E000-$FFFF
c = Whether indirectly accessed as code.
(e.g. as the destination of a JMP ($nnnn) instruction)
d = Whether indirectly accessed as data.
(e.g. as the destination of an LDA ($nn),Y instruction)
P = If logged as PCM audio data.
x = unused.
Never heard of AUL files, what are those?
