Mainly I was waiting to reboot into Linux to try to build this.
You may want to add some instructions for building the game/emulator.
For the emulator, I'd never used cmake before (sort of) so I didn't know to run cmake .
Then the error about SDL (needed libsdl-dev package or similar)
For the game, I'm currently downloading a Linaro ARM toolchain on a slow connection but I don't anticipate any further issues.
