This is for Dwarf Fortress v0.40.24 SDL.
Place noparamlimits.dif in [your Dwarf Fortress install directory]\hack\patches\v0.40.24 SDL
. If any of these folders do not exist, create them, unless it's the hack
folder that doesn't exist, in which case you need to install DFHack. (If it's your Dwarf Fortress install directory that doesn't exist, what are you doing here? Get Dwarf Fortress first!)
To use, type binpatch apply noparamlimits
at the DFHack prompt. If you want to apply this automatically, add it to your dfhack.init file.
