So this has been a project that has been cooking in the oven for about a year in the form of a bounty. The goal is to come up with a way to not only dump all the textures of a PlayStation1 game, but also to replace them with user-supplied textures.

Doing this is hard with PlayStation renderers due to the general low level of abstraction of these renderers, which is why it’s not exactly a commonplace feature in many PS1 emulators.

So far we have let it cook slowly in the oven. However, the recent release of people preparing a Proof Of Concept demo in the form of a Chrono Cross texture pack and the circulation of a modified Beetle PSX HW core that adds support for custom texture injection has led us to make the decision to include this feature already in the buildbot cores rather than wait it out. We hope by doing this, that this feature can organically grow and that more people start taking an active interest in making their own texture packs this way for their own favorite content. Libretro is all about enabling people the power and freedom to do what they want with their legally bought content, after all.

Requirements/Availability
Should only require the Vulkan renderer and a graphics card that is compatible with the Vulkan API. Will not work with either OpenGL or software rendering.

To use a textures pack you'll have to extract the textures in a [game_filename]-texture-replacements/ folder inside your game directory, where "[game_filename]" matches the actual filename of the file you're using to load the game.

Here's an example with Suikoden II:

Suikoden II (USA).bin
Suikoden II (USA).cue
Suikoden II (USA)-texture-replacements/
