'Abacus copy protection'

UPDATE: closer inspection with SC shows the following track / error layout:

Track 36 : No SYNC marks / READ ERROR 21 on S0-16

Track 37-40 : Sector header not found / READ ERROR 20

Simply editing track 36 with Star Commander doesn't do the job - so track 37 and up seems relevant.

Note that cracked versions usually don't have any error info in their D64, but usually check T35-40 right before they start (as can be observed in VICE).
This is at least the case for the 1.0 version floating around (D64 has CRC 5d412d28; probably TOSEC?).
