Got it thanks to BigSes on PST -
Hi guys! With default controls, I just went into vs mode, put the controller on the floor (held in place between my feet, sitting Indian style), and used my right hand to go back and forth quickly on the left and right D-pad arrows while spamming L2. It unlocked almost right away, I tried for like 10 mins to do it normal and couldn't get it.
Its basically how us old schoolers would play Track N Field on the NES back in the day, the quick left-rights while spamming the L2 button. Wanted to bring that up. Thanks!
