Ghidra RPX/RPL loader

This is a (WIP) simple extension to open .rpx and .rpl files with Ghidra.

Dependencies

This loader uses the Gekko/Broadway processor definitions for Ghidra if found - it is recommended that this should be installed prior to using the loader.

https://github.com/aldelaro5/ghidra-gekko-broadway-lang

The loader will fallback to the default PowerPC processor if the Gekko/Broadway language is not found, but do not expect good results if the program uses any paired single instructions.

Building

Ensure you have JAVA_HOME set to the path of your JDK 17 installation.
Set GHIDRA_INSTALL_DIR to your Ghidra install directory. This can be done in one of the following ways:
- Windows: Running set GHIDRA_INSTALL_DIR=<Absolute path to Ghidra without quotations>
- macos/Linux: Running export GHIDRA_INSTALL_DIR=<Absolute path to Ghidra>
- Using -PGHIDRA_INSTALL_DIR=<Absolute path to Ghidra> when running ./gradlew
- Adding GHIDRA_INSTALL_DIR to your Windows environment variables.
Run ./gradlew
You'll find the output zip file inside /dist

Installation

Copy the zip file to <Ghidra install directory>/Extensions/Ghidra.
Start Ghidra and use the "Install Extensions" dialog to finish the installation. (File -> Install Extensions...).

Usage

Choose the Gekko/Broadway/Espresso language if asked
