PKG files are common for DLC or PSN games.

python3 pyps3checker.py my_game.pkg

The script will validate the digital signature. If it says "Digital signature: VALID", the PKG is untouched.

brew install python

Verify the installation:

python3 --version

Expected output: Python 3.11.x or higher

Fix:
You haven’t installed Python or it’s not linked. Re-run brew install python. If that fails, download the official installer from python.org. pyps3checker mac

Create a file verify_all.sh:

#!/bin/bash
DATE=$(date +"%Y%m%d_%H%M%S")
LOGFILE="$HOME/Desktop/ps3_check_$DATE.log"
for ISO in "$1"/*.iso; do
    echo "Checking $ISO" | tee -a "$LOGFILE"
    python3 ~/pyPS3Checker/ps3checker.py iso "$ISO" >> "$LOGFILE"
done
echo "Done. Report saved to $LOGFILE"

Make it executable: chmod +x verify_all.sh. Run with ./verify_all.sh /path/to/isos. PKG files are common for DLC or PSN games

The script has no GUI; it runs entirely in the terminal. The basic syntax is:

python3 pyps3checker.py [options] <file_or_directory>

The tool works by parsing the PlayStation 3’s proprietary file structures and comparing computed checksums against expected values. For Mac users, this is one of the few lightweight, non-WINE-dependent solutions available.
