Having some trouble with this on Linux emu, both this version and if I build it myself. I can run piano.rom just fine but this rom just comes up as a black unresponsive screen in the emu. ??? help? ideas?
Are you on the latest version? Could you tell us what steps you did to run Yufo?
We updated the guide yesterday, it covers how to launch roms:
