Tool Documentation (create-gp4)

Summary

create-gp4 takes a content ID and list of files and produces an output GP4 project file. This tool is based on John Tornblom's create-gp4 prototype python script.

Build

The tool is written in Golang. Commands should be the same between Windows and Linux assuming Golang is installed on the target system.

Building is straightforward, simply go to the root directory of the tool (/src/tools/create-gp4/) and run the go build command.

There is a shell and batch build script to compile create-gp4 on all platforms (Windows, Linux, and macOS).

Usage

The create-gp4 tool requires two arguments. These arguments are -content-id and -files respectively. The -out path for the gp4 file is optional, and defaults to homebrew.gp4.

Usage of create-gp4:
  -out string
        output gp4 to write to
  -content-id string
        content ID of the package
  -files string
        list of files to pack into the package

Example Usage

./create-gp4 -out IV0000-BREW00083_00-HELLOWORLD000000.gp4 --content-id=IV0000-BREW00083_00-HELLOWORLD000000 --files "eboot.bin sce_sys/about/right.sprx sce_sys/param.sfo sce_sys/icon0.png sce_module/libSceFios2.prx sce_module/libc.prx"

Source code overview

All the source code resides in main.go since the program is relatively trivial.
