-- TECHNOLOGY

1.MODULE patch mode

  The entry points are searched with NID in memory and hook it.

2.SYSTEM CALL hook mode
  modify and hook SYSTEMCALL jump vector table.

-- LIMITATION

The UMD emulation is still developing,not a perfect.

1.MODULE patch mode
  supported non-encrypted ELF only.
  supported single module only,sub modules can't hook.

2.SYSTEM CALL hook mode
  still developping

  The jump table base address should be necessary.
  Firmware 1.00 = 0x88015b30
  Firmware 1.50 = unknown

-- How to use

1.copy 'EBOOT.BIN' and 'hook_boot.ini' to 'x:/PSP/GAME/[gamename]'
  (use PBP tool for Formware 1.50)
2.modify 'UMD0_PATH' in 'hook_boot.ini'
3.copy all UMD files to 'UMD0_PATH'.
4.execute 'HOOK BOOT' from PSP.

-- UMD emulation

1.path is changed from 'disc0' to 'fatms0:' dynamically.
2.loadable KernelModule from MS.
3.emulate the UMD Drive condition.

-- FUTURE PLAN

1.free file name replacement.
  The change of the game directory name.
  The share of the movie and sound file to make it the smallest.

2.UMD emulation with FTP client.
