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 only comes with Windows binaries, though the user can build both Linux and Macintosh versions from source. 3DGE was actually continued from 1.32 rather than 1.35, and the codebases were merged shortly after, as well as switching back to GLBSP rather than TinyBSP that EDGE 1.32 contained.

As well as adding new features, the team also incorporated fixes to a few 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. 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.

The Dream3DGE branch (and EDGE 1.29 that it was based off of) was abandoned officially and rewritten/integrated back into 3DGE with version 1.37. The Dreamcast code utilities KallistiGL instead of OpenGL for important rendering functions concerning the SH2 CPU.
