PSP ISO Tools for Redump

This repository contains portable Python replacements for the tools required by Redump when submitting PSP games. IsoBuster, Hashcalc and SFOInfo are replaced by the redump_psp.py script.

Given an ISO file, it will generate a pre-filled Redump submission, containing:

• File size
• Hashes (MD5, CRC32, SHA1, SHA256)
• ISO PVD Hexdump
• SFO information

sfo_info.py can be used by itself as a standalone sfo_info.exe replacement.

Requirements

• Python 3 (>= 3.6)
• pycdlib

Windows exe builds are available in the release tab.

Usage

redump_psp <iso_file> [--out <output_file>]

sfo_info <iso_file>

Sample output

It is formatted for Redump forum posts, hence the [code] tags. You can easily remove them in redump_psp_template.py if needed.

Automating it

Below is a simple script I've made that auto-generates submissions for every ISO in the given directory. Make sure it only contains PSP ISOs.

import os
from redump_psp.redump_psp import gen_psp_redump
import argparse

parser = argparse.ArgumentParser(
    description='Find ISOs and generate redump submissions')
parser.add_argument('dir', type=str, help='Directory')
args = parser.parse_args()

for root, dirs, files in os.walk(args.dir):
    for name in files:
        if not name.endswith('.iso'):
            continue

        iso_name = name[:-4]
        if iso_name + '.nfo' in files:
            continue

        print(f"Generating submission for {name}...")
        gen_psp_redump(os.path.join(root, iso_name + '.iso'),
                       os.path.join(root, iso_name + '.nfo'))
        print("Done.")
