3DGE

3DGE, also called Hyper3DGE, is the successor to EDGE. Originally created to power the Hypertension TC, its goal was changed to a full-fledged successor to EDGE after Andrew Apted discontinued the parent port. The first version, numbered 1.35d, was released on 2011-04-11. The latest version is, released on. The first version of Dream3DGE, numbered 1.29dc, was released on 2013-09-18, and is playable on the. The port comes with Windows and UbuntuAMD64 binaries, though the user can build Linux, Macintosh, and Dreamcast versions from source. 3DGE was initially forked from EDGE 1.32, and the codebase was merged with the final EDGE 1.35 release.

As well as adding new features, the team also incorporated fixes for overlooked bugs left behind from EDGE. The name is a play on EDGE - the "3" is to symbolize the third line of continuation from EDGE and DOSDoom, and is pronounced the same as EDGE. The port is hardware-accelerated only, and also implements support for KallistiGL (PowerVR).

A few notable mods in development are Abrasion by Kronos (utilizing the MD3 code), Doom Forever by Chris Mullen (CeeJay), and a sequel to the Marc A. Pullen (Fanatic) mod QDOOM. SLaVE and Hypertension: Harmony of Darkness are two commercial products using this engine, both being developed by Isotope Softworks and published by Goat Store Publishing.

Dream3DGE is a Sega Dreamcast-only port of EDGE 1.29, and has high compatibility with pre-1.31 mods, as it cannot currently run anything created with EDGE 1.31 or above. It must be built with KallistOS. It contains most, if not all, functionality from the parent port. This branch (and EDGE 1.29, on which it was based) was abandoned officially and rewritten and integrated back into 3DGE with version 2.0. The Dreamcast code utilities KallistiGL instead of OpenGL for important rendering functions concerning the SH2 CPU.
