EDGE-Classic is a fork of the EDGE source port by Andrew Apted (andrewj), Dashodanger and Luke Brennan (Lobo). It is based off EDGE 1.35, the final original EDGE release from April 9, 2011.

It focuses on solving long-standing bugs and adding some quality of life features, such as extensive music format support. Additionally, EDGE-Classic targets older or less powerful hardware compared to the 2.x fork, 3DGE.


EDGE-Classic was formed out of a need for lightweight and advanced port for the Raspberry Pi, as well as dissatisfaction with progress on the 3DGE port. Luke Brennan, aka Lobo, suggested to Dashodanger to use EDGE 1.35, as that ran well on the OpenPandora handheld. Initially the focus was on fixing some bugs for the platform, but the scope rapidly expanded. A name had to be chosen, and due to the port targeting legacy hardware by design, EDGE-Classic was chosen and first released on December 18, 2021.

Since then, development has shifted, supporting new cross-platform standards like DEHEXTRA and UDMF, with a special focus on music support so that various sound sources can be played as alternative soundtracks.
