Giz Decrypt

A simple utility to decrypt and patch Gizmondo games to work with any SD card and Gizmondo running Service Pack B.

Usage

1. Download the latest version from "Releases"
2. Insert the SD card you want to decrypt into your PC
3. Rename "autorun.exe" in SD root to something else e.g. "decrypt.exe"
4. Copy "autorun.exe" from the downloaded release to the SD root
5. Run the SD card on a Gizmondo device

Once the process completes, all executables in the SD root will have a decrypted copy with a ".out" extension.

Building

The project includes a Dockerfile with a build environment for building Gizmondo executables. To build the project run:

podman build -t giz-decrypt .
podman run --rm -it -v ".:/workspace:Z" giz-decrypt
