There are some feature that don't exist in the game normally, but that you can introduce by editing the code in a text editor. For example: random pickUp, random set, numbers from 100 to 255 etc.
However, putting solutions that use those features feels like it would defeat the purpose of having a repository where people can look up record solutions, - if those solutions cannot be written without 3rd party software.
Or maybe not a new category, but a new tag: Year NUM - NAME (TYPE) - (in-game/editor).txt
