Original Pull Request: https://github.com/stenzek/duckstation/pull/2224

State: closed
Merged: No

This is still a work in progress, but I'm PR'ing it so anyone interested can mess with it.

Rough TODO:

  • Support dumping by VRAM write and clut/palette.
  • Support replacing textures.
  • Improve dumping further and reduce the number of junk textures (it's much better than the initial version, but there's still room for improvement.
  • Implement on backends other than DX11.
  • Make sure it doesn't crash the software renderer.
  • Save texture replacement state to save state (at the moment it will be lost when you load state).
  • Save texture dumper state to save state (same as replacements, it's lost when loading).
  • Texture filtering options for the replacements (mipmaps/trilinear).

NOTE: This is a completely different/original implementation when compared to the functionality in beetle-psx. Texture packs created for it are not, and never will be compatible.
