Main Index Routine Index Memory Index Previous Page Next Page [$038A-$038B] = 49 FD : not used ??? (RL6 code area) I suspect this is used for adjusting the parity of Track 18 Sector 15 (loaded to [$03xx]) which needs to be #$35 (see $0206 routine). The area [$0381-$039B] is not encrypted making this adjustment more easy. RapidLok-Reference: --- : --- Previous Page / Next Page
