The result of a proper engine clone is often the ability to play a game on modern systems that the old game could no longer run on. The new engine reads the old engine's files and, in theory, loads and understands its assets in a way that is indistinguishable from the original. Game engine recreation is a type of video game engine remastering process wherein a new game engine is written from scratch as a clone of the original with the full ability to read the original game's data files.
