Browse Source 
This will allow you to use SBI/LSD files with real discs, if your
drive does not support reading subchannels, or has an incorrect
skew.

CHD images with built-in subchannel information are also supported.
If you are playing directly from a disc and your CD/DVD drive does not support subchannel reading, or has a skew with the returned SubQ, you can place the SBI file in the `subchannel` directory under the user directory, with the serial or title of the game.
