Data/Data Format - What does LBA 0 mean ?

[Hacker999]

There are more than just 2 methods to make a DC game boot.

Audio/Data refers to having a dummy audio track in the first session, then having the actual data (the game or whatever it is on the disc) in the second session.

Data/data is similar. The difference is that you replace the dummy audio file with a dummy data file in the first session. You can also have actual game data as opposed to a data dummy file in the first session.


LBA is Logical Block Address. Basically each file has it own LBA(s) when on a disc/image. The files are in the order of the LBA. One file can range from more than one LBA depending on it's size. You can use a program like ISOBuster to see the LBA of each file on a disc/image.


When selfbooting with an LBA of 0, you must use the data/data format. Obvously because if you used audio it takes up space and you can't start at 0. This format is only useful/necessary when selfbooting a game that is either very large and you need the extra space or your DC cannot read the audio/data format.
