First of all, I am not the original author of Emumaster.
You can find the original announcement by elemental here:

I like Emumaster very much and am very thankful for the great work by elemental and for releasing it as Open Source.
Already some time ago, I started to add patches to Emumaster for building and running Emumaster in Mer/Nemomobile/Plasma Active.
The latest patches are intended to port Emumaster to Qt5 such that it can be used with the latest Nemomobile versions as well as Sailfish.

Please note that all this is a work-in-progress.
While some things already work pretty well, many other things don't work at all or not as expected.

So far, I tested the SNES emulation on my Jolla phone.
It seems to work reasonably well.
One thing I am still missing is sound output.
For some reason the pulse audio output seems to be suspended.

The Amiga and GBA emulations are also included, right now.
However, I didn't test it yet.
The other emulations are currently disabled.
With the latest version of the patches, all shown emulators are included.
So far, I successfully tested SNES, GBA, and Amiga.
With Amiga, you need to experiment with the controls but in general it seems to run.

You can find my forked repository of Emumaster that already includes many of the patches here:
https://github.com/ruedigergad/emumaster
I also set up a project on build.merproject.org:
https://build.merproject.org/package...ko%3Aemumaster
From there you can get the latest .rpm for installation:
http://repo.merproject.org/obs/home:...mv7hl/armv7hl/

I attached some screenshots of the current state.
All help is highly appreciated.

Edit: Update, Amiga is also included now.

Edit2: Update, NES and Pico are also included now.
