Configuration for the Potatoptimize

You can override the default config via the potatoptimize.properties file found in the config folder

// At the moment you cannot disable an entire package. This will be implemented eventually!
mixin.memory = false

// You must disable a specific optimization like this:
mixin.memory.memory_reserve = false
