I installed retropie some weeks ago and I must say it´s a fantastic job.
Im experiencing an odd error with scummvm emulator. Whenever I try to start it, I only get a black screen. I can confirm that the emulator is running because I can hear the music of the games, but the screen is black.
I started a desktop session and tried to run scummvm and then it works correctly. The problem only happens when I try to run scummvm from the command line or directly from emulation station.
Im running a berryboot installation with OpenElec and Raspbian Wheezy for ES. Scumm version is 1.4.1 I believe. I tried to update but it said I have the latest version.
