Brook Super Converters are awesome! For only $35, they bypass Street Fighter V’s PS3 Legacy Controller nonsense and they also avoid the dreaded 8-minute PS4 timeout issues (after a firmware update). They do not require a PS4 Controller/DS4 to use!
I have personally confirmed the white PS3 to PS4 adapter as working with a PS3 Madcatz TES stick and Qanba/Eightarc Fusion and Q4 sticks (in PS3 mode). Generally, the adapters will work with any wired PS3 or Xbox 360 pad/stick that is not auto-detect. They even have PS2-to-PS4 converters for you PS2 pad users! However, the devices do NOT work with PS360+ PCBs (because they are auto-detect).
