4. Open the original PRX (~PSP) in the hex editor, highlight header 336 bytes (0x150)
5. Select in the menu of the hex editor File -> Export -> C and save as DATA.c
6. Now open kirk.c and DATA.c in Notepad++ and also open the main.c from source - you should see a similar section
7. Highlight the digital code from the kirk.c and replace it with the main.c 272 bytes (0x110)
8. Highlight the digital code from the DATA.c and replace it with the main.c 336 bytes (0x150)
