I must start it with root permissions to make the GUI work.
Without that, started with menue icon, there is only a black screen.

The tab row is only show half.

Will give it a test.

edit: same problem as in ArnimS version. If you'll choose a kick.rom in another path as given by emu, it crashes.
Workaround is to move the kick.rom in the preset path.

edit 2: load a disk image crashes too.
