Done.
Nope, the current version is an obsolete, unstable, without theme, need to apply change and build it yourself code.
I would say its far from usable for most people even if they capable of cherry-pick patches and build.
list of problems if without patch:
1. hard limited 8mb of total buffer which share between audio, font and themes - its pitiful small for any theme greater than 540p.
2.
https://github.com/Rockbox/rockbox/commit/6499ce3e445e1acc5f5707fd164ad5e3c5ab0a43this commit introduced a new issue. when the internal frame buffer resolution is different than the current running device, instant of draw part of the display or have black bar surround the framebuffer area, it give you the black screen of the death.
before this commit it was possible to run a 400x800 build on 480x854 or 540x960 device but not anymore now.
somehow make the android fragmentation worse. require one-to-one build.
3. this build will crash in Android 5.0 for sure and there is no tool can trace what cause the crash.
to me this is the last straw.
