/**
@file main_gbmeta.ino
This is Gamebuino Meta implementation of the game front end, using the
official library. Leaving out the library bloat could probably optimize this.
To compile using Arduin IDE you need to copy this file as well as all
necessary .h files into a project folder, then open the project and compile.
Do NOT put .c and .cpp files into the folder, stupid Arduino tries to compile
them even if they're not needed.
DON'T FORGET to set compiler flag to -O3 (default is -Os). With Arduino IDE
this is done in platform.txt file.
