Shin Ruckus and Dan Filner have an emulation beta for Windows that is (mostly) finished. Though it still needs some polish, it is far and away the closest emulation to arcade perfect. The significance of this is that, despite the myriad official home console ports and efforts from the MAME team, rom encryption still hasn't been cracked. This encryption causes all kinds of havoc - from animation bugs to hitbox problems and other related gameplay issues.
Getting the Moo Emulator implementation of Primal Rage finished with that last 10% and officially available on GOG will -FINALLY- after thirty long years do what no one else has done up to this point. If anyone else is up to the task of releasing an arcade accurate version of the game, I welcome them, but as of writing, it doesn't exist officially.
For my point of view, Primal Rage was the fighting game that taught me fighting games. Hot take, I know, especially since this game released smack-dab in the middle of some of most influential arcade fighters ever made. It's often criticized for its decision to use level-edge for its specials (hold the buttons first, then joystick movements); but in a niche where games from the era feel like copies of each other, Primal Rage dared to be different. It created systems that would become the norm for fighting games going forward: comeback mechanics, jump cancels, and chaining normals.
My experience with the game peaked when I finished the arcade version on the hardest difficulty without taking damage. A feat that took six months of practice, and an additional two weeks' worth of attempts. FG fans deserve a taste of what it would be like if Capcom hadn't dominated the scene.
