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.

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
