Is it safe to assume that this patch fixed also the UV coords for WM? So in case we can delete the hext files for FF8 directly in this PR. What do you think?

Nope, let me explain:

The Maki patch happen right after the parsing of file data, it prevent the game to alter the UVs (the game does it to use bilinear filtering on textures)

Later the game filters which vertices are currently displayed on the screen and produce a big array of GPU commands with various things like vertices. But it alters the UVs again in some cases in this big array. Later again, the game reads the big array and transform the UVs into floats. That's where my patch fixes things

So in short:

1. WMX parsing
2. UVs modified (2 added/substracted) <-- Maki patch to remove this
3. Vertices targeting
4. UVs modified (targeted to the right position in the texture chunk of the VRAM) <-- My PR stores the missing bits caused by this modification
5. Big array of GPU commands created with the targeted vertices
6. Execution of GPU commands
7. UVs converted to float <-- My PR restores the missing bits here for more accurate floating values

I can integrate the maki patch into FFNx and make it an option in FFNx.toml if it is needed

No worries, it's not a high prio, we can include it in code any time :) Thanks for working on this in the meantime
