Another brief update:
I have to keep it short due to time constraints.

I just build: emumaster-0.3.1-10.77.1.jolla.armv7hl.rpm

This one re-enables several patches for:
- Enable Sound
- Amiga Support
- GBA Support

The NES&Pico patch did not work, for now.

I also added some hack to work around the sizing issues but I cannot elaborate on that, right now.

The version is based on commit 4f40a85b141e402b7c302fe31159c15c2467161d from my github repository.
The reason for this is that, apparently, something regarding the build options had changed, which I already had fixed in my experimental setup.
