Lakka use Openelec as a base for their retro emulation console

Lakka have a stable build for the Banana Pi, and their project files are here: https://github.com/libretro/Lakka/tree/lakka/projects
If you compare this to the master Openelec tree: https://github.com/OpenELEC/OpenELEC.tv/tree/master/projects

The Banana Pi project looks compatible with Openelec, I will over the next few days try and build Openelec using the Lakka project files and report back if I'm successful.

Looks like the Lakka dev team fixed hardware acceleration on the Mali GPU too, see http://www.lakka.tv/articles/2015/01/20/new-hardware-odroid-c1/

As the C1 has a Mali chipset for video acceleration, we worked these last days fixing it For Allwinner boards (Cubieboard 2 and Cubitruck). The black flickering and black bacground issue when using lakka / xbm menu are now fixed.
Great news! Thx!

Yes!
Please give me a link and I'll test it!

No build yet due to having to prove the Lakka compile method works for a Lakka build first.

taking time to do each part

enredar  
me too! if is possible, tell us how we can help you.

Looks more like the Lakka dev team fixed 'the black flickering and black bacground issue when using lakka / xbm menu'?

The Mali-450 used in the ODROID's SoC is far more powerful but with less attention being paid regarding OSS drivers for graphics acceleration than the Banana Pi's Mali-400...

its not stable because the composite AV out port is not working properly. The picture is out of scale. Also the script.bin to enable the AV out port should come as some sort of download on the lakka site to enable users to see this and to see this as a development that is also needed.

most retro consoles worked on CRT tv's and I would expect that the banana pi could work and scale the picture properly over the composite video port. I know there
is HDMI but I still use a CRT tv.

the current build works ok though over HMDI. still sucks on a CRT tv though over an AV phono cable.

Cubieboard 2 and Cubietruck both use the Mali 400 MP2, same gpu as the Banana Pi.

Lakka built, now trying to build Openelec
