    -- Note: Currently the Debug Mode kinda Sucks. by that I mean it only adds the Debug Room, which only has a sign and an encounter in it.
    --       I am planning on adding more to the Debug Room and POSSIBLY add the Deltarune debug mode visuals.
    --       On another note, currently the Chapter Selection library only has one use: Completion save files. In the future, if I do port the Deltarune debug mode, it will be added there to be used with your other mods + More.
    --       Oh Also, the 'Mod.undertale' config option will load the 'Check out Undertale' screen every time the Chapter Select mod loads. I know, that's not supposed to happen, but you can just add a flag to change that if you want. I'd rather just have that instead of making the screen only accessible once. (Though if you guys want me to change it, let me know in the mod's post in the Kristal discord.)
