What is a GS dump?
A GS dump is an export of instructions sent from the PS2 core to the "Graphics Synthesizer" (aka "GS"). The instructions can be replayed in PCSX2, and even on a real PS2, to quickly reproduce, inspect, and resolve graphics errors. This allows helpers to figure out what's wrong with a game, and developers to fix the emulator.
Where do I make the dump?
Get to a point in your game where the graphics bug is clearly visible. The issue must appear on your screen in order for it to be captured in the dump.
How do I make the dump?
Use the key combination Shift + F8 or use Tools > Save Single Frame GS Dump
Where does the GS dump save to?
GS dumps are saved to the /snaps folder.
- On Windows, this is in the same directory as the PCSX2 executable.
- On Linux and Mac, use
Tools > Open Data Directory
Your graphics settings DO NOT affect the dump, and you will not need to change renderers, hardware fixes or any other settings.
