Help with Repacking a PSP .pkg for a Fan Translation

[PhillyPlaya]

I’m working on a fan translation for Evangelion Jo on PSP and have run into a roadblock with repacking the game’s files. When I extracted the ISO,I found a .pkg file (NEVA.PKG) this file contained all of the game files that needed to be translated. I opened the .PKG file using Noesis and translated all needed files in the folder which is now NEVA_files. I successfully translated the game’s text, but now I need to repack everything so it runs in PPSSPP.

What I’ve Tried:
• Extracting the .pkg using Noesis (this worked for unpacking).
• Editing the text files and keeping the same file structure.
• Rebuilding the ISO with UMDGen without repacking the .PKG and leaving it as a folder (NEVA_file) (but the game won’t load).
• Renaming NEVA_files back to NEVA.PKG but leaving it in folder format(didn’t work).
• Looking for a PSP .pkg repacker, but most tools seem to be for PS3/PS4.

Issues:
• PPSSPP won’t recognize the rebuilt ISO.
• I’m not sure if the game is expecting a .pkg file instead of a folder.
• I haven’t found a way to properly repack NEVA_files into NEVA.pkg.

Does anyone know the correct way to repack a .pkg for a PSP game? Or if there’s a specific tool I should use? Any help would be appreciated!

Hi! I don't know much about repacking games, but I can try to run the repacked iso on a PSP, if you want to. Or if you can send me the translated files and the original iso you're working with, I can try to repack it with a few tool I have, and report to you the results

Sounds like you will have to repack the PKG file which probably acts like an archive file. It's not a generic file type so you may have to do the analysis by your self. But since you can simply extract everything using Noesis, it shouldn't be too complicated - at least the content is not encrypted or compressed.
