True-hitbox marker patches for arcade shmup ROMs

The project provides IPS patches that inject a tiny sprite into CAVE/IGS‑PGM shmup ROMs, marking the exact player hitbox during gameplay. It works with MAME and FBNeo, letting players and developers see true collision points without altering menus or assets. Users supply their own legally‑obtained ROMs and apply the patches via the included scripts. This niche tool helps speedrunners, researchers, and enthusiasts debug and analyze game mechanics more precisely than existing overlay hacks.
