Zzxzz

From Redump Wiki

Redump name for a DRM made by SDC and more commonly known as Dont bother burn (DBB). Used almost exclusively by Swedish made games and can be identified by the presence of a zzxzz folder on disc as well as a very specific track structure.

#	Type		Pregap		Length		Sectors
1	Data/Mode 1	00:00:00	(Game data)	(Game data)
2	Data/Mode 1	00:00:00	00:02:50	200
3	Data/Mode 2	00:03:00	00:06:64	514

Where track 3 also carries sectors with bad sync.
