Protection	Steinberg Protection scheme B: one of three randomly chosen reads must return a read error (track 33: 21, track 34: 22, track 35: 27). Use the patched G64: Vice does not reproduce error 27 on track 35 with the original G64 or P64, so about one start in three fails. In the patched G64 the header checksum of track 35 sector 0 is inverted, so the error is returned every time.
Working?	Yes, with the patched G64 (tested with Vice 3.10). With the original G64 or P64 about one start in three fails the protection check.

Original dump. In the emulator (Vice 3.10) the protection check fails in 33% of all starts: one of its three variants (error 27 on track 35) never passes. Reset and load again. On a real drive this variant depends on a misread of track 35; how often it fails there has not been verified on real hardware.

Protection signature on track 35 patched specifically, such that the check passes in 100% of the starts in the emulator (Vice 3.10). Emulator only; the behaviour of a disk written from this image has not been verified on a real drive.
