Your controller must adhere to the following:
Operation other than movement [Light attack, middle attack, heavy
attack, special technique, abilities (default: R1), throw (default: L1),
guard (default: R2), overhead attack (default: L2)] Cannot be assigned
to multiple input mechanisms.
When moving with a direction key or button, the same movement operation
cannot be assigned to multiple input mechanisms.
If the left and right direction inputs and buttons are entered at the same
time, both inputs must be enabled, or both inputs must be disabled.
If the up and down direction keys and/or buttons are entered at the same time, the up input must take priority.
Legacy controllers are not allowed.
("Legacy controllers" refers to arcade sticks and controller devices that are native to the PlayStation®3)
If players use a legacy controller device, that offending player will be disqualified. However, devices that are native to PS4 (and still work on PS3) will be allowed to be used.
