What's the problem? Describe what went wrong.

Some textures appear a bit mangled, regardless of rendering back-end selected (incl. the software renderer), or the resolution.

What steps will reproduce the problem?

  1. Install Dolphin from scratch (fresh install).
  2. Launch the game. The issue is visible in the main menu, the character select screen, and other places.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes: Dolphin v5.0-20193

Is the issue present in the latest stable version?

Yes: Dolphin v5.0-19870

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 11 x64
32GB of RAM
CPU: Intel Core i9 13900K
GPU: NVIDIA GeForce RTX 4080

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

In the screenshots, you will notice:
A) The graphic for the "A" button is messed up
B) The graphics for some of the character portraits are messed up

I found some YouTube videos of people playing the same game using Dolphin, some as old as 5 years ago, and the issue is visible there.

Looks like nibbles of C4 textures are decoded in the wrong order.

Can you attach a fifolog of the issue? (If the file is too big you can compress it with 7-zip).

Attached are two FIFO logs. I am not sure if I did it right, hopefully this works.

Fifo1: Main menu (where "A" button graphic is glitched).
Fifo2: Character select screen (where some portraits are glitched).

I went ahead and bought a copy to verify this and this is actually hardware accurate. The devs must have incorrectly set up their textures when porting between PS2/GC/Xbox.
