Custom PPSSPP shaders

[r1g1sw2]

Hi everyone,

I wanted to share a 20:9 ultrawide patch for Tekken 6 (USA – ULUS10466) that I’ve been testing on PPSSPP.

Game: Tekken 6
Region: USA
Game ID: ULUS10466
Target aspect ratio: 20:9
Test device: POCO F5 – 2400x1080
Emulator: PPSSPP Android

The patch corrects the 3D rendering for 20:9 and includes several selectable camera-distance options.

In PPSSPP, set:

Display Layout & Effects -> Stretch

Then enable:

- Screen - 20:9 Ultrawide
- Only ONE camera option

Camera options:
- Camera - Original
- Camera - Slightly Wider
- Camera - Wider
- Camera - Widest

Code:

_S ULUS-10466
_G Tekken 6 [USA]

Important limitation:
This currently fixes the 3D rendering only. The 2D HUD/UI is still based on the original 16:9 layout, so HUD elements can still look horizontally stretched when PPSSPP stretches the final framebuffer to 20:9.

I experimented with separate HUD correction, but Tekken 6 appears to use multiple 2D rendering paths and those attempts caused graphical issues, so I’m only sharing the stable 3D patch.

If anyone can help identify the proper 2D/HUD scaling path, it would be great to eventually make this fully corrected for 20:9.

If anyone tests this on other 20:9 devices, please share your results and which camera setting looks best.
