[Ohrrpgce] Android port

Sat Jun 1 22:59:42 PDT 2013

I managed to figure out your makefile problem from the error messages.

I'm surprised that Bell of Chaos runs that quickly on your tablet,
nearly 5 times faster than my phone. A single core of a high end
desktop CPU is nowhere 5 times faster than the lowest end one (well,
actually it is if you compare to an Atom instead). I guess that on a
device with an actual GPU a lot of CPU is freed up for the
application... but if it's running at <4 fps, then there isn't much
GPU emulating to do anyway :)

I should have specified the button mapping: top left is ESC, top right
is Enter, and the other four are arrows. Menu and Search are also
Enter, and BACK is Esc.
