An extension for Ghidra that adds support for the PlayStation 2.
This extension is based on the original ghidra-emotionengine project, with a number of changes.
- Disassemble and decompile EE-specific instruction sets (MMI, VU0 macro mode, etc).
- Recover data types, functions and global variables from ELF files with
.mdebugsections with the included STABS Analyzer. - Import PCSX2 save states.
- Fix references to global variables with the MIPS-R5900 Constant Reference Analyzer.
- Support for Ghidra 11.2.1.
Release builds are available on the releases page. Unstable builds, generated whenever there is a push to the main branch, are available here. To install the package, follow the instructions in the Ghidra documentation.
If you want to build the extension yourself, install gradle and run:
gradle -PGHIDRA_INSTALL_DIR=/path/to/ghidra buildExtension
Modern versions of PCSX2 store save states using zstd compression by default, which Ghidra's zip implementation doesn't support. To work around this, if you are using PCSX2 v2.1.178 or higher you should make sure that Tools -> Show Advanced Settings is checked, then navigate to File -> Settings -> Advanced -> Savestate Settings and change the Compression Method option to Deflate64. If you are using an older version, you will have to change SavestateZstdCompression to false in the EmuCore section of your PCSX2.ini file.
Try disabling the Decompiler Parameter ID analyzer.
Enable the Use Deprecated Demangler option in the settings for the Demangler GNU analyzer.
