It would likely be enormously useful in this to have a development wiki behind the games that devs and people that played the games may know the engines, file formats, save file formats, compilers, Langs, etc.

Old devs of the games could enlighten the game preservation community anonymously.

Game dev was a frontier and hardware pushing activity even in the directx era. The magic shift code for ...quake??? Was just the tip of the iceberg.
