Ghidra RPX/RPL loader

This is a simple extension to open .rpx and .rpl files with Ghidra 10.4.

The loader includes the Gekko/Broadway/Espresso processor definitions that are based on the Ghidra-GameCube-Loader.

In case the Espresso language is not found, the loader will switch to the default PowerPC processor. However, it is not advisable to expect satisfactory results if the program uses paired single instructions.

Imports in official .rpl/.rpx files may display as "func_xyz" instead of the function's actual name. This issue can be resolved by running the fix_primary_imports.java script, which is included with this loader.

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
• Run the fix_primary_imports.java script if imports are not displayed properly
