Another very cool project in this space is TRX, which is based on a decompilation of the original Tomb Raider 1 & 2 source code:<p><a href="https://github.com/LostArtefacts/TRX">https://github.com/LostArtefacts/TRX</a><p>Of the various Tomb Raider fan engine projects, this is basically the "vanilla, but modernized and well-maintained" historical archival option.<p>I contributed the MacOS port to this one, and last year I dabbled a little in porting an older random git snapshot to the web:<p><a href="https://eikehein.com/stuff/sabatu/" rel="nofollow">https://eikehein.com/stuff/sabatu/</a> (using a fan level, as to not post the original game content online)<p>It's a very rough hack, so it's not upstream at the moment.<p>The TRX team is a wonderful and passionate bunch of people to hang around.
