# Ghidra RPX/RPL loader
This is a (WIP) simple extension to open .rpx and .rpl files with Ghidra.
This is a simple extension to open .rpx and .rpl files with `Ghidra 10.4`.
# Dependencies
The loader includes the Gekko/Broadway/Espresso processor definitions that are based on the [Ghidra-GameCube-Loader](https://github.com/Cuyler36/Ghidra-GameCube-Loader).
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.
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.

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.
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>``
