Playstation 2 Master Disc Patcher for MechaPwn
By: MottZilla

Use this program to patch images so the Mechacon in consoles exploited by Mechapwn will see them as
Master Disc and allow read access without using Force Unlock. This will allow CD-R, DVD-R, and DVD+R PS2
games to play once booted by a method other than the normal OSD. FreeMCBoot's fastboot or ULE work great.

The program expects CD-ROM images to be 2352 bytes per sector format and DVD-ROM to be 2048 bytes per
sector. The program will abort if it doesn't seem to be either of these things. The program may also abort
if it cannot find the system.cnf file. If all goes as expected it will backup the sectors before patching
to either CD_Sectors.bin or DVD_Sectors.bin depending on disc type. These backups should only be needed
if you accidentally patched the wrong file. Otherwise you can ignore it.

Testing Info:
I have tested this patcher with MechaPwn on my SCPH-50001 console with FreeMCBoot. Discs should load via
FastBoot, 'Launch Disc', or ULE's PS2Disc option.

CD-ROM games used for testing were:
 Gradius III&IV (Usa), Marvel Vs Capcom 2 (Usa)

DVD-ROM games used for testing were:
 Shinobi (Usa), Soul Calibur III (Usa), Phantasy Star Universe (Usa), Twisted Metal Black (Usa)

You can change the Master Disc region by changing the letter in region.ini
J = Japan, U = USA, E = Europe, W = World

If Region.ini is missing it will default to USA. I haven't tested if the region setting matters.

It may be possible to patch an image for both ESR and Master Disc if you patch for ESR first. This is
untested. I have not looked into mixing Master Disc patching with FreeDVDBoot patching. If sectors 14&15
are not used then it may be possible.
