Converting format depends entirely on what the file contains. Most common PKG files are either macOS installers PlayStation backup packages 1. Converting macOS Installers (Mac/Windows) If you have an InstallAssistant.pkg

Conclusion

1. Create a new folder named as the Game ID (e.g., BCUS98234).
2. Inside that, create a folder named PS3_GAME.
3. Move the entire contents of your extracted RPCS3 folder (the USRDIR, TROPDIR, etc.) into the PS3_GAME folder.
4. Create an empty file named PS3_DISC.SFB inside the same directory as PS3_GAME (not inside it). You can create this by making a blank text file and renaming it.

Why is it not a 1-click convert?
A PKG file lacks boot sector information and the specific file system structure (UDF or ISO 9660) that an ISO requires. Therefore, the “conversion” is actually a two-step process: extract → rebuild as ISO.

1. You will see the raw installer files (Setup.exe, .cab files, etc.).
2. Select these files.
3. Right-click and choose "Add to Archive" (using 7-Zip or WinRAR).
4. Change the archive format to zip.
5. Once created, simply rename the extension from .zip to .iso.
