// Struct viewer visualizes objects data in game memory using types and symbols fetched from a Ghidra project.
|
|
// It also allows to set memory breakpoints and edit field values which is helpful when reverse engineering unknown
|
|
// types.
|
|
//
|
|
// To use this you will need to install an unofficial Ghidra extension "ghidra-rest-api" by Kotcrab.
|
|
// (available at https://github.com/kotcrab/ghidra-rest-api). After installing the extension and starting the API
|
|
// server in Ghidra you can open the Struct viewer window and press the "Connect" button to start using it.
|
|
//
|
|
// See the original pull request https://github.com/hrydgard/ppsspp/pull/19629 for a screenshot and how to test this
|
|
// without the need to set up Ghidra.
