Think you need to learn MIPS code, and there are videos on youtube..
I think it is possible to download a de/compiler and change the xbmc binary too..
It could be very time consuming and hard though.
If you do give it a shot, I'd be grateful if you fix the media player issue whilst your in there, maybe integrate spotify and sort out pulsar too please..
Seriously though, imho, this will never be fixed.
I speculated in February that we wouldn't see another update from the beta 1 (beta 2 with BH a some drivers were missed) and seems I wasn't far wrong.
We need someone to build a new image using kodi open source code for MIPS processor otherwise what we have is what it is - closed source and belongs to vu+
To learn MIPS, to code an image, to make it work, would take a very long time, and probably a lot of money to fund a university course to understand what you'd need to do.
At the moment Gotham 13.2 does a job, not great job but a lot better than anything we had before. Which is probably why we shouldn't complain.
I'm back using windows version with the htpc route much less stress. Wasted days of my life messing with the beta getting nowhere near the ease of use of the windows or Linux versions.
All part of the hobby though eh
