Hey Garvalf! - I used your image because building mine failed. You might want to consider including a mapping file with the zip because the default keybinding is a pain.. Also submit your build via git to the master project, they should put it on the website!
The only thing you should note is you need to install pulseaudio
From the terminal
sudo apt-get install pulseaudio
I would also suggest installing SSH server because it makes setup much easier
Things I need to get working personally (would love tips)
- Auto run pig (or hack the build in menu to replace sunvox)
- Auto pair my joypad
- Mount the filesystem over samba or sshfs or something.
ps do NOT upgrade the firmware to the latest 8gb image, everything seem much flakier.
