How to use the LibIRD library

LibIRD was originally made for creating reproducible, redump-style IRDs when dumping PS3 discs with MPF. If you wish to integrate LibIRD into your own application, the following are some examples.

Reproducible, redump-style IRDs

The standard way of generating a reproducible, redump-style IRD is with a redump ISO file and a redump key file (e.g. http://redump.org/disc/28721/key/):

byte[] discKey = File.ReadAllBytes("./game.key");
IRD ird = new ReIRD("./game.iso", discKey);

Alternatively, the disc key can be extracted from a GetKey log file obtained from a PS3 (or when dumping using ManaGunZ)

IRD ird = new ReIRD("./game.iso", "./game.getkey.log");

Custom IRDs

Functionality is also provided for creating IRDs with a custom disc key, disc ID, and PIC:

byte[] discKey = new byte[16];
byte[] discID = new byte[16];
byte[] PIC = new byte[115];
// Set vars to desired values
IRD ird = new IRD("./game.iso", discKey, discID, discPIC);

As before, a GetKey log file can also be used with an ISO to create a custom IRD, with the disc key, disc ID, and PIC all being extracted from the log file (rather than just the key for redump-style IRDs).

IRD ird = new IRD("./game.iso", "./game.getkey.log");

Finally, an existing IRD file can be read to create an IRD:

IRD ird = IRD.Read("./game.ird")

An IRD can be then be tweaked, its fields printed, and written to a new IRD:

ird.UID = 0x9F1A51D8;
ird.Print();
ird.Write("game2.ird");
