Thanks for all the hard work! I don't have much time to maintain stuff like that, but it's amazing that someone picked up what I did and made it a simple one click install for Lutris users.
I'm not keeping track of the changes in the Unity assembly, just edited the binaries in dnSpy and wrote all the custom Linux code there (on second thought, I probably should... it'll be for the next time then). I haven't created a GitHub account for all this stuff, but I probably will when I find the time to make one and upload the sources there. Feel free to redistribute it wherever you want, the version number is fine too.
PD: I was going to post a pastebin including the libaokanaproc.so source now since it was very basic, but I lost the source while reinstalling my PC! It's very basic though, basically just libwebp and a specific function exported. I'll also upload the source of the tool I wrote for the Switch patch, an (un)packer for the .dat files, when I take care of setting up github stuff.
