Abystus made a mame hack to showcase the unused sounds from the beta/prototype of Killer Instinct arcade. I uploaded this video showcasing the sounds. It can also show the Thriller Instinct boot image although it only displays for a millisecond. Also, a few other kids don't do drugs splash screens. Here is a video showing a very early build of KI Cinder's name is Meltdown Sabrewolf's name is werewolf The character selection screen is completely different and there is some stage differences. Combo names and announcer voice are different as well. I wonder if the prototype HD image exists anywhere. I know the is a proto 4.7 rom but it doesn't change anything graphically. I'd love to pop that proto hd into my KI arcade cab!! On to KI2 Abystus also just posted this video showing some unused animations and moves called dominations (humiliations) from KI2 Post any other new beta/proto finds for KI on this thread!!
