Keymap for the YH820 fits much better for the YH920 anyway.

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations

known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs

Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
  official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
  ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
  Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual

to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed

./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk

the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)

The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.

Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.

* sudoku: make colour icons (without screen was squeezed)
* jewels: add colour bitmaps
* pegbox: make game fit on screen (add small header bitmap),
  improve keymap

I left the original pegbox keymaps for samsung's YH-92x,
because they seem to make some sense there (YH92x has a
REC switch instead of pushbutton).
Someone with a YH9xx target has to check what is better...

Although both players basically have the same keys, the
differences in the layout is rather big, so I think both
deserve their own keymaps.

(On the yh820 the FFWD/PLAY/REW buttons are located above the
direction keys, on the yh920 at the side of the player.
Furthermore the yh920/925 has a REC switch, whereas
yh820 has a push button.)

This patch completes the plugin keymaps for the Zen X-Fi3 and enables those plugins for compilation.
One key was changed in "button-target.h" for compatibility with Rockboy.
This also caused the changes to "keymap-zenxfi3.c", to keep the stock functionality (no further changes in here).
