Too bad you would not code a tool to rip them from PS2 and put them in PSP versionI would suggested looking on youtube for the scenes from the PS2 version. I have not dumped the text since it is all in image/video format.
Instruction to patch the game:
1) You need to dump your UMD, or use this release : Phantom_Kingdom_Portable_JPN_PSP-Caravan (filename cvn-pkp.iso)
2) Download the patch
3) Download xdelta UI
4) Backup ISO
5) Run xdelta UI
6) Patch PKP iso with PKP_patched_v0_x_x.xdelta in xdelta UI
7) Either use a PSP emulator or download to PSP and enjoy
