The PlayStation 1: LibCrypt Protection Dumping Guide was a deprecated guide intended to identify if a game has LibCrypt and how to dump it.

Detecting and dumping LibCrypted data
Method one: psxt001z
For this you need psxt001z 0.21 beta 1. Insert your PlayStation CD in drive and type in command line:
psxt001z --libcryptdrvfast [drive_letter]
for example,
psxt001z --libcryptdrvfast D:
In case tool reports error, try method two. If eveything is OK, it will start scanning disc for modified sectors. Please note that "modified" doesn't mean LibCrypted, because sectors contents also depends on disc quality and drive. When scanning finished, the number of modified sectors will be printed. Please include "sectors.log" file (which contains list of modified sectors along with their contents) when posting disc info to the forum or using internal site function. If error occured during the scanning process, try running the tool again or method two.
Method two: CloneCD + psxt001z
For this you need CloneCD and psxt001z 0.21 beta 1. Install CloneCD, insert your PlayStation CD in drive, run CloneCD, press first button, select drive from the list, then select "Game CD" profile (not "Protected PC Game"), and start dumping. When image is created, delete all files but "IMAGE.SUB". Then type in command line:
psxt001z --libcrypt [path_to_sub]>sectors.log
for example,
psxt001z --libcrypt "C:\IMAGE.SUB">sectors.log
Please include generated "sectors.log" file (which contains list of modified sectors along with their contents) when posting disc info to the forum or using internal site function.
Storing LibCrypt data
To store LibCrypt data, we use SBI format, which contains modified-only sectors with Q-channel data. SBIs for LibCrypted discs can be downloaded from PSXDB (link "SBI subchannels" on protected disc page). SBI format is supported by:
- ePSXe, PlayStation emulator. To use SBI, name it after EXE name, leaving extension .sbi, and put in /epsxe/pathes folder. For example, "SLES_025.29.sbi" for PAL version of Resident Evil 3: Nemesis.
- P.E.Op.S. CDR plugin, which is supported by many PlayStation emulators. To use SBI, open plugin settings window, select "Use subchannel SBI/M3S info file" option from "subchannel reading" menu, then choose your SBI in "File" field.
Unfortunately, no disc emulation or burning software currently supports SBI, neither do image formats. Our new image format with SBI support is in early development stage.
