Dan Lawton and Ken Beckett released the source code to Color Dreams‘ “Crystal Mines“. It was a former unlicensed commercial game for the Nintendo Entertainment System/Famicom.

The game is NOT released to the Public Domain / Freeware pool yet and possibly will never be, but the source code is available for free but bound to “Ken’s License”. All other artwork related to the game is still under copyright, such as the graphics, levels, sounds and music.
