Tombstone city is a game developped in 1981 by Texas Instrusment for the TI99/A4.
My very good friend Buzz has developped his own version of this game for Linux, Windows and the Nintendo DS. Few days ago he added sound to SDL version.
See http://buzz.computer.free.fr/ for details.
This version is a simple update from the original version. Music intro, and game sounds are now fully supported.
