Oops, I did the thing where you leave a mod on when demonstrating something else. Shoulda turned the hitboxes off. It really does just blend in and you forget about it after a while.
I recently found the functions for saving and loading state used for GGPO and quickly threw this together in a couple days. There's still some stuff I'd like to add to it, but I want to port my old frame meter overlay to the new mod loader so it'll work on Linux first.
