Adressed review comments. I've noticed you're using mkDerivation instead of wrapQtAppsHook, is that prefered? I just did this based off of this wiki page.

I based my work off the Citra emulator package, which I'm familiar with. Both emulators originated from the same development team so I figured there's probably a lot of similarities between the two and it would be a good place to start.

On the nixpkgs manual it states:

Locating runtime dependencies. Qt applications need to be wrapped to find runtime dependencies. If you cannot use mkDerivation or mkDerivationWith above, include wrapQtAppsHook in nativeBuildInputs

So it sounds like you can use either, but mkDerivation is preferred.

Ah, i didn't see that wiki page. Switched over to it.

Indeed, though from what I've heard from over at their Discord server they mostly share frontends at this point.

Still working on figuring out vulkan support, slowed by compile times.

Here's the error in the logs:
Render.Vulkan <Error> video_core/renderer_vulkan/renderer_vulkan.cpp:CreateInstance:101: Vulkan library not available

Just tried adding vulkan-headers to nativeBuildInputs and vulkan-loader to buildInputs, that didn't work.

I tried that last week as well, the LunarG vulkan-tools did not seem to work either. Compile times are extremely slow, so its a pain to test indeed.

Good news, I have working vulkan. Let me clean this up a bit and I'll send it your way.

This seems to be working well: https://github.com/JoshuaFern/nur-package-lab/blob/master/pkgs/misc/emulators/yuzu-mainline/default.nix

Do you have sound by the way? I'm playing Pokemon Mystery Dungeon DX and I'm soundless over here. Not sure if it's a problem with this game, or if the sound isn't working in general.

Edit: Adding alsaLib to the buildInputs fixed the sound for me.

Thanks a lot! I couldn't figure this one out myself.

Whoops, did not notice that one as i muted it beforehand since it'd sound all crackely because of the framerate. I'll add alsaLib, thanks again

I think the solution I've just pushed is a bit clearer, as we just drop QT's mkDerivation all together, instead of overwriting it.

Yes, definitely. I just wanted to confirm gcc10 was the solution. Great stuff!

Anyone wanna merge this?

Would love to see this finally get merged :)

Hi! I'm an experimental bot. My goal is to guide this PR through its stages, hopefully ending with a merge. You can read up on the usage here.

@jtojnar anything else before a merge?

Tried to build it, turns out Nix thinks its unfree. Why is this package marked as unfree?

I don't have a Switch so I can't verify if the software functions, but it launches.

Thanks @IvarWithoutBones and all 🎉

I'm really happy we finally managed to get this merged.
Thanks everyone for the extensive reviewing and helping out on this PR, I've learned a lot.
