Spider-Man/X-Men: Arcade's Revenge (Genesis) - Reduced Enemy Invincibility PatchFor whatever reason, in the Genesis version, most enemies are given a whopping 20 frames of invincibility each time they receive damage.
This patch shortens their invincibility to only 2 frames, to make a part of the gameplay more in line with the SNES version.
