GammaTag is an alternative firmware for the MilesTag outdoor laser tag system.
See http://lasertagparts.com/mtdesign.htm for information on MilesTag.
GammaTag aims to be a highly configurable, 100% compatible edition of MilesTag. The key difference is support for 2x16 and 4x20 LCD displays.
GammaTag also aims have pre-defined situations which are simply written to the PIC (over an IR link) and the game commences.
Written using SDCC, and currently utilising conventional Linux build methods (./configure and Makefiles) with a windows buils system coming soon.
