Confirmed working with TU6!
Cheat 3 -- works great, can turn on and off 2 hit kill (normal 2 hit combos or super combos works).
cheat 2 -- Infinite health works great, but if I don't turn on cheat 3, LB+down won't kill opponent.
Cheat 3 + 2 = Only super combos works for 2 hits kill. Normal 2 hit combo won't kill.
^_^ here is the result. if you still need more testing , please let me know~ ^_^
