Ydgpatch - Link

What is YDGPatch? YDGPatch is a specialized modding/patching tool and file format (often seen as .ydgp or .pchtxt ) used within the Yuzu Emulator (and its forks like Ryujinx, to a lesser extent). Its primary purpose is to inject custom code or modify game behavior at runtime without permanently altering the game’s original ROM or executable file.
