Introduction taken from readme.txt
============
As many of you are probably aware, the PS2 has problems running DVD9 games backed up onto dual layer media
due to the problems reading from the second layer.

This is because the data format on burnt DL discs is different than on
pressed discs (burnt = OTP, pressed = PTP).

However, we have discovered a software hack which allows the PS2 to read even burnt OTP discs
resulting in working dual layer backups!
Toxic firmware for DMS4 chips already includes auto-patching functionality
which applies our software hack on the fly when booting games on dual layer media.

For those without a DMS4, we present the Toxic Dual Layer Image Patcher!
The patcher works by applying our software
hack to the game image (.iso, .gi etc) before burning.
Once the hack has been applied by our patcher,
burn the modified image to dual layer media and play!

This method will enable anybody with a modchip capable of booting
DVD9 media to backup and _play_ DVD9 games such as Gran Turismo 4.
