Detailed information on reactivating (or activating, depending on your view) the unused slots available in the M2/Mi Sounds file. This is a great way to add new sounds, without losing what's already there. The doc mentions that you can see the technique being used in "M1->Mi Hunter conversion patch that this doc is bundled with"-while the patch does have these docs bundled, this version is just the docs. If you want the patch, you need to get it from the Alterations section.
