Hi, I am a secret famous game creator

 I just want to send you guys the best controls, no big deal, no profit either, I just get it from the Stars, here it is, I hope you apply, this is one of my best configuration layouts

Square Jab 
Triangle Straight 
Circle Right Hook
X Left Hook
Square X Left Uppercut
Triangle Circle Right Uppercut
and all switch for Southpaw
Or Tekken Style instead of Fight Night Round 3 or UFC Undisputed 3 Kicks and Punches techniques, but this version, you require each roster a different version of fighting style or D-pad change fight styles

L1 standing kicks, moving forward kick technique, moving back kick technique, same as special punches
R1 For blocking all
L2 for defense grapple
R2 for offense grapple
and move away or forward with defense and offense with the left analog and right analog stick, and press L2 and R2 forward to takedown then use R2 to throw if timed right or stronger unless he or she has good defense L2 will win for them
Ground gaming too also, when submission L2 R2 breathing like from GTA 5 Yoga scene and press R2 to execute submission or L2 to escape, whoever has better strength and stamina wins or um technique strength and stamina, there ya go
Same as Grapple, wrestling, throws, Muay thai throws, Muay thai clinch

Up d-pad Boxing, brawling, Kickboxing, Taekwondo, Karate
Down d-pad base martial art: Grappler, striker, or submission
Left d-pad MMA, Jujitsu, Brazilian Jujitsu
Right d-pad  Muay thai, MMA
or remove all that and just select each fighter for their own skill sets
Press select to toggle HUD On or Off
and Press Start Online to pause game for 1minute and either they leave or stay till 1 minute and they can pause too, simultaneously until agree to stay until they come back or 1minute, change to 5 or 15 minutes

Try looking into the database archives, I set a system where the more you use a  character despite the stats,  the more improved you become with it, like a Pokemon stored in your game, or a horse lol
