Black screen with Mupen64

Hi, I’ve sucessfully compiled everything using guide https://github.com/libretro/RetroArch/w … 28Linux%29, but for some reason Mupen64 emulation does not work. It just freezes on black screen with 100% cpu load. It did not work few months ago with Fedora 20 and behaves the same now with Fedora 21. Am I missing something or is it known bug? I could not find any info besides it should be probably already fixed (viewtopic.php?f=0&t=2447&p=18547&hilit=mupen64#p18565). Thanks.
