-- Noita settings/configuration modifications.
-- We try to keep persistent modifications to a minimum, but some things have to be changed in order for the mod to work correctly.

-- There are 4 ways Noita can be modified by code:
-- - `config.xml`: These are persistent, and Noita needs to be force closed when changed from inside a mod.
-- - `magic_numbers.xml`: Persistent per world, can only be applied at mod startup.
-- - Process memory: Volatile, can be modified at runtime. Needs correct memory addresses to function.
-- - File patching: Volatile, can only be applied at mod startup.
