Source code for Gameboy for MIST

This is source code of a gameboy implementation for the MIST.

It's based on the t80 CPU core. A minor fix was needed for the "LD ($FF00+C)" instruction.

The audio implementation has been taken from the PACE framework. The original file is available in the pacedev svn.

Binaries are available at https://github.com/mist-devel/mist-binaries/tree/master/cores/gameboy.
