This video showcases the KO animations for all the 15 boxers on this list. A special thanks to Akiteru and Awosomeandy for the KO animations that can only be accessed via hacking and cheats.
Bald Bull, Mad Clown, Hoy Quarlow, and Rick Bruiser all have KO animations but are not possible to get in realtime. However, with the use of cheats, you can force the game to trigger them, which is what I did.
Bull, Clown, and Rick KO barriers are impossible because the boundaries to get the KO are simply too fast for a human to do. (Probably a 1second window if I had to guess after the second phase) Their health refill is just too high for it to be done. Hoy is a softcoded fight meaning the only way to get the KO is if you force the game to do by using cheats.
Mr. Sandman is the only boxer that does not have a KO animation, even with the use of cheats and hacks it's impossible. (He is what we call a hardcoded fight)
Hope you guys enjoy the video, be sure to like and share this video! Also, sorry if the audio might sound a little weird. Wasn't really in the best position to get the clips.
