Please linux support
Since someone still cares, there's 2 ways to get it working :
1) Use the android app in a https://www.android-x86.org/
virtual machine with KVM ( I used libvirt to manage it ), just make sure to enable VirGL , I was able to test this one and everything worked.
2) Wine has been making progress on mfplay.dll and mfplat.dll ( both are needed for the windows version ) and with 4.19-staging ( installed by playonlinux ) I was able to start it and log in. Videos don't play for some reason but songs seem to start and audio output seems to work. I was unable to test it further since I no longer have a guitar.
Hope this helps.
