I want to share my knowledge about this project! I know your hack, it has different songs, I like it .. thanks for the feedback !! I wanted to add all the voices and sounds to the game, but unfortunately the limitations of the game discouraged me. But I have dozens of game addresses, for example, increase the number of characters in Friendship, change the scenery of Shao Kahn and Motaro, etc.
More than putting back Johnny Cage in the SNES (which is a pain in the ASS to resize all of his sprites, kudos for the guy who did it in Sega)
I want to restore back Sheeva into the game, even if it limits the number of stages. And restore the stage cycle. Still I don't know why The Rooftop and The Pit 3 are excluded from the cycle.
PM if you want me to give you all I know about UMK3 tweaking.
