Compatibility Report

This suggests that an effect has some render state change we've never seen before. The latest FNA will tell you what it is, but you'll have to manually build and install this into the wine-mono path to see it:

Okay, I think I need some help then. I don't feel really smart here. Hitting the Makefile just gave me a bunch of "not found" outputs in Terminal(RESNAME, RESDIR, SRC, release, mcs, etc.). Do I need to do something with the make-command or moving the source elsewhere? Am I right the wine-mono path is in the game specific compatdata directory? Probably "~/.steam/steamapps/compatdata/314450/pfx/drive_c/windows/mono"?

The build is kind of messy right now - there's a wine-mono branch that has some special WinForms stuff, so a build would look something like this:

git clone --recursive git://github.com/madew0kherd/FNA.git
cd FNA
git pull git://github.com/FNA-XNA/FNA.git
git submodule update
msbuild FNA.sln /p:Configuration=Release
cp bin/Release/FNA.dll ~/.local/share/Steam/steamapps/common/Proton\ 5.0/dist/share/wine/mono/wine-mono-4.9.4/lib/mono/gac/FNA/19.11.0.0__0738eb9f132ed756/FNA.dll

The wine-mono and FNA GAC folder may not be precisely this, but those can be tab-completed pretty easily. Downloading the package that provides msbuild should pull in everything else you need to build.

Okay, I ended up stucking on the dotnet msbuild /t:Publish FNA.Core.csproj /p:Configuration=Release command.
here's my output:

chaika@chaika-A320M-S2H-V2 ~/FNA $ dotnet msbuild /t:Publish FNA.Core.csproj /p:Configuration=Release
Microsoft (R)-Build-Engine, Version 16.4.0+e901037fe für .NET Core

/usr/share/dotnet/sdk/3.1.101/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.CrossTargeting.targets(27,5): error : The 'Publish' target is not supported without specifying a target framework. The current project targets multiple frameworks, please specify the framework for the published application. [/home/chaika/FNA/FNA.Core.csproj]

If I do dotnet msbuild FNA.Core.csproj /p:Configuration=Release I get an error saying I need .NET Framework Developer Packs, which appears to be Windows only (No Windows here right now). And another one.

Any idea?

The Core project won’t work, try this instead:

msbuild FNA.sln /p:Configuration=Release

Oh dear, my bad. Had errors with the FNA.sln first, then experimented too much.
dotnet msbuild /t:Publish FNA.sln /p:Configuration=Release was without errors, but I can't find any output file. Without /t:Publish I still get an error.
Assuming this is right so far: I miss the ~/FNA/bin folder.

Strange, I would expect bin to be there... I think the msbuild log will say where it wrote all the files; if needed you can do -target:Clean if it doesn't tell you the output location.

I looked up the render state value and it seems to be for sampler state modifications... which is weird considering that's supposed to be a separate series of state changes. Anyway, hack go here:

https://github.com/FNA-XNA/FNA/commit/0a45d07d90ef2bd0f284c17bb10f3c22bf627c24

This game should work after wine-mono updates to FNA 20.04.
