I have tried to extract game certain files from Bad Apple Wars on PSVita and have hit a roadblock.
The three main files are union.cpk, sc.cpk and pr.bin
I had some success with CriPakTools and was able to extract files from union and sc which resulted in nearly a thousand files with no extensions.
All files involved in various states (original, extracted, split) are located below.Original FilesSplit FilesExtracted Files
My main goal is to get these files to an editable state so I am able to do an asset swap (JPN>ENG) which will make it playable for older firmwares.
Edit: using quickbms results in the "not utf table" for all three files.
