But now done properly! Basically, a bunch of improvements were made to the script. The previous attempt at this conversion was quickly followed by a rollback since I realized that the script was overlooking certain things that made most of the packs hit or miss whether they would work. A few things missing were:
- It only tested the values from 1 preset. Now, each shader gets compiled per each preset, like what Cemu would do. It also merges the changes done for each preset into one. This should solve cases where one shader would define things separately or repeatedly from preset to preset.
- All* of the shaders are tested to see if they use the converter used the right values for the locations for Vulkan.
Both of these *should* mean that they should both compile and be linkable in Vulkan, which means that I don't have to test each individual shader to see if they work. I will release the two scripts (one used for converting, one used for checking the right values for the locations) tomorrow so that other people might be able to help, if they want. It's fairly straightforward now at least.
* Organize workaround graphic packs
Pretty hard to organize these correctly, but according to our discord discussion, this was the best layout from a bunch I proposed, together with some suggestions.
* Add V4 converter script and instructions on how to use it
Now everyone BotW is done and all of the bugs have been kinked out using it (hopefully...), here's the release of the converter script in all of it's very badly coded glory. I hope I didn't leave too much debug glory in there...
Also, I hope that I didn't make too many grammatical mistakes in the instructions, but hopefully it's easy enough to follow.
* Update rules.txt
add "(OpenGL)" to title and rendererFilter to this pack since it creates crashes on vulkan and is not nessecary due enforcement of GX2DrawDone on vulkan
* Update rules.txt
Since it's not possible to update 300+ shaders manually and automation was possible, I thought that I'd take the honor and create a script that's able to automatically convert all of the shaders to be cross-compatible with Vulkan. And change the graphic pack versions to version 4 of course.
Also, the script has some nifty testing code which compiled every shader as OpenGL and Vulkan, but for that see the details that I've written below.
**Here's the script that I've made to do all of this. No manual edits were needed:**

Both had some weird stuff going on which the Vulkan converter couldn't successfully compile. Also, the presets in the anti-aliasing might be nice, but they are not even used in the shader 🤔.
Since I wanted to make sure that I didn't broke the shaders after converting the shaders to Vulkan, we need to check if all the shaders weren't broken. Since we're talking about like 400 shaders checking all of them is pretty much impossible and even then,
So, the obvious solution was to automate the checking. Not as simple as you'd think, because in 300 of our shaders we use preset variables which without replacing the value like Cemu does, will make the shader error regardless. So I also implemented some functionality that would read the preset values and types out of the rules.txt file and replace them in the shaders using that information. And then we use Khronos' glslang to compile the shaders, using both OpenGL and Vulkan.
The result was that glslang found quite a few errors in some of the shaders, which I fixed in this commit. I'm considering adding this rules.txt parsing and automated shader compilation testing to the build process.
Also, I fixed Clarity's name and description since Monochromia isn't available anymore and Xenoblade's resolution pack had a lot of weird blank lines before their #version declaration, which my converter didn't like.
Remove 30 fps lock packs for Hyrule Warriors, and Paper Mario Color Splash. These games run at the correct frame rate as of 1.15.7.
Removed the Paper Mario intro softlock pack. Also fixed in 1.15.7.
Also removed the version indicator in Windwaker's contrasty file since any updates to that number would remove all the configuration set by the user for that pack.
They were switched from the previous versions. Besides that, somebody reported it being different then before, but I can't find the difference. (There's a slight difference because the vibrancy in one shader was 0.1375 instead of 0.138 but I doubt this would be a big difference and it does simplify it a little bit).

This shader allows for changing of the color for the pixel-mess texture and or making it transparent/opaque. However its also responsible for the Cursor Text in selection screen. So messing with this Shader also messes with the Cursor text. The best way to hide the pixel-mess is to do it the old "version 2" way.
