* '''"v1" protection''': Which has a standardized dumping method that generates a reproducible hash. These discs are usually produced with an indigo-colored bottom, or occasionally a clear (silver) bottom. Supported by [[redumper]] and DiscImageCreator (with /sf parameter).
* '''"BIG.DAT" protection''': Dump with the standard method. These discs are usually produced with an indigo-colored bottom, or occasionally a clear (silver) bottom. Contains corrupted "BIG.DAT" file, and/or other file with similar corruption.
* '''"v2" protection''': Which does not have a standardized dumping method and does not generate a reproducible hash. These discs generally have a black-colored bottom (or a very dark indigo-colored bottom), or a clear (silver) bottom (as with some "v1" discs).
* '''"PS2/Datel Ring" protection''': Requires using the redumper command "redumper --rings --correct-offset-shift". These discs generally have a black-colored bottom (or a very dark indigo-colored bottom), or a clear (silver) bottom (as with some "BIG.DAT" discs).

* '''"PS2/CodeBreaker Ring"''': Requires using the redumper command "redumper --rings --correct-offset-shift". This type of protection has been observed on Code Breaker v9.0 and later discs as well as [https://redump.info/disc/124717/ Cheat Code Demon].

For dumping these see [[Dumping_Guide_(redumper_CLI)#Irregular_Disc_Types|redumper guide section for irregular disc types]]. This type of disc has only been observed with "v1" protection.

There are a variety of unlicensed PlayStation 2 protection methods which affect the way the discs are dumped.

Types of unlicensed PlayStation 2 discs and related copy protection:

  • Discs which contain codes for both PlayStation 1 and PlayStation 2 consoles: These are PlayStation 1 formatted discs and do not contain copy protection.
  • "BIG.DAT" protection: Dump with the standard method. These discs are usually produced with an indigo-colored bottom, or occasionally a clear (silver) bottom. Contains corrupted "BIG.DAT" file, and/or other file with similar corruption.
  • "PS2/Datel Ring" protection: Requires using the redumper command "redumper --rings --correct-offset-shift". These discs generally have a black-colored bottom (or a very dark indigo-colored bottom), or a clear (silver) bottom (as with some "BIG.DAT" discs).
  • "PS2/CodeBreaker Ring": Requires using the redumper command "redumper --rings --correct-offset-shift". This type of protection has been observed on Code Breaker v9.0 and later discs as well as Cheat Code Demon.
  • Physical Ring protection: Common on Swap Magic discs and which exists on discs in addition to other protections. In addition to using the appropriate methods required to getting with the above protections, see Ringed Disc Dumping Guide.
  • Fake TOC / mini-cds with full-sized TOC / Data covered by label: For which a higher sector count is given by the TOC than is physically readable by a disc drive. For dumping these see redumper guide section for irregular disc types. This type of disc has only been observed with "BIG.DAT" protection.
    • NOTE: Sometimes mini-CDs with full sized TOCs[1] are also released with a full-sized CD variant[2]. In which case if the readable data matches, the dumps are combined into a single redump entry[3].
    • NOTE: Sometimes CDs where the label covers part of the data (double-sided PS2 / DVD-Video discs)[4] are also released as variants where the label does not cover the data (single-sided PS2 disc)[5]. In which case if the readable data matches, the dumps are combined into a single redump entry[6].
