Convert encrypted PSN Classic PSX PBP file to an unencrypted PBP file

convert_pbp.sh

#!/bin/bash
# the purpose of this script is to make all the PSN PSX games I purchased on my PS3, PSP, PS Vita
# playable in DuckStation and Batocera
# 
# you will need to build the following projects:
#
# https://github.com/AKuHAK/psxtract
# https://github.com/bryanperris/PSXPackager
#
# I downloaded the zip files and build them that way, you might need to fix the path for your setup
# 
# my current system is Debian 12 on an core i3
#
# this will also delete the ROM folder after it is done outputing the file
#
# this should be the PSX output dir
DIR=/export/psn-psx
# this is the directory with the EBOOT.PBP file
ROM=$1
