Doom64 EX

Doom64 EX is a reimplementation of Doom 64 for Windows by Samuel "Kaiser" Villarreal. It is based on Doom3D, though rewritten for OpenGL rather than DirectX, and including some bug fixes from Boom and MBF. It aims to recreate the look and feel of Doom 64 as closely as possible, based on specifications obtained through reverse engineering, similarly to how Kaiser also created SvStrife.

The first public version of Doom64 EX was released on July 10, 2008. The latest version is 2.2, released on March 4, 2012.

Compared to the Doom 64: Absolution TC, the principal difference is that Doom64 EX uses the original data. A tool provided with the port can create a DOOM64.WAD IWAD from the ROM.
