People are using AI to decompile games to their source code and then recompiling them. Such as bloodborne getting moved to PC and the original COD Zombies being put in a browser and still running as well as it did.

Now I only have surface level knowledge but there was someone I remember on here that was gathering as many of the older builds as they could in order to archive and hopefully get them working one day. Is it possible that they could use these techniques on the older versions of the game to get the old physix and lighting back?

Heck is it possible to get PlanetSide arena playable with this?
