PPS:
I could build emumaster with gstreamer 1.0 dependencies.
You can get version: emumaster-0.3.1-10.70.1.jolla.armv7hl.rpm
from my OBS repository: http://repo.merproject.org/obs/home:...mv7hl/armv7hl/

However, please be aware that I only installed it and started one SNES emulation without trying much else.
One thing is already apparent: The controls may be over/under sized depending on you screen resolution.

Any way, feedback is as usually appreciated.
However, due to my time constraints there may be quite some delay until I can reply.
