ZDoomGL (v1)

ZDoomGL is an OpenGL port of ZDoom, maintained by Timmie. Originally it was developed by Michaël "Kokak" Ryssen, but once he got a job working at UbiSoft, development on the port slowed considerably (and eventually stopped). In 2003, Timmie picked up development, and rewrote the port from scratch to be up to date with what was, at the time, the latest version of ZDoom. The latest official release dates from the 27th of April 2004.
