what are you trying to use the tool for mate?
to make a ripkit you must have ORIGINAL.PKG and RIPPED.PKG in folder then what it does it is compares the 2 files and changes them etc... so basically for example dead rising 2... i made a huge mod for that but dont want to post the whole game as its too much data... so i made a modded pkg file and used this tool to create a ripkit... then you come along and you dont need to redownlod the game you just need the 10mb patch file (give or take depnding on changes) then my app will use your pkg file and apply mods/
cheats etc
if your trying to do the backport then you must do this:
as for the backporting its currently working in 1.6 but you must use other tools first... UnFself is needed.
extract your package or eboot.bin and param.sfo take these files and place them into my BackPort folder
now place UnfSelf.exe in there too and drag eboot.bin on this file.
now rename eboot-decrypted to old.elf
rename sfo to old.sfo
run my app and click backport
now you have new.elf and new.sfo put these back where they belong... trouble im now having is how do i make elf file back into bin file?
