RELIVE

RELIVE is a popular Open Source fan recreation of the ALIVE engine which is being developed by Paulsapps with the help of some other contributors. RELIVE uses reversed engineered source code from Abe's Oddysee and Abe's Exoddus re-written to support other operating systems such as: Windows, Linux, macOS and more. Eventually it will support PS1 audio quality and fix the music bugs on the PC version. It has been tested and speedran by several YouTubers and the speedrunning community hopes to use RELIVE in the future once all the RELIVE bugs have been fixed. Currently, Oddysee can't be completed without saving and restarting the game in longer categories, but with RELIVE it will hopefully be runnable without having to restart the game.

Before the RELIVE engine, Paulsapps was working on an Oddworld Level Editor for Oddysee and Exoddus which was popular for people on YouTube to show their custom Oddysee/Exoddus level mods.
