PYIRD is a program for validating PlayStation 3 JB folder game backups using IRD files. It supports automatic fetching of IRD files from online database and provides detailed file-level integrity verification against the original decrypted game structure.
Just download pyird_Windows.zip from Releases, extract the archive, and run the .exe.
Just download pyird_Linux.zip from Releases, extract the archive, and run the executable.
Download x64 or Arm build depending on your device from Releases, extract the archive, and run the executable. MacOS might say the app couldn't be verified, go to settings, privacy and security, and allow anyway.
Once the program is open, click "Select Game Folder" and choose a folder containing PS3_GAME.
PYIRD will then attempt to auto-load a matching IRD file. If one is not found locally, it will fetch it from the online PS3 IRD database. You can also manually load an IRD by clicking "Select IRD File".
After loading the IRD, the program will scan and validate the game folder, comparing each file against the IRD. The results are displayed in the table, showing:
- File Name
- Size
- MD5 checksums
- Validation result (OK, Missing, or Invalid)
Extra files in the folder will also be highlighted.
- IRD Files: Stored in an
irdfolder in the same directory as the program. Filename must include the product code at the beginning in the formatBLES01750orBLES-01750for local check to work. - Logs: Stored in
logsfolder in the same directory as the program.
