I want to play Black Zero

Step 1: Go to the character select screen and put the cursor over Zero

Step 2: R1 (6 times) then press X + Start

Actually, you have to put the cursor over Zero, hold R1, press Right on the D-Pad 6 times, release R1 then hold Circle and press Start.

Thank you. But I don't want the answer. I want PC Ver. Black Zero

It's the same. You just have to press RB instead of R1 and B instead of Cicle.
I don't know what are the keys on keyboard.
