I wanna make one just like it or if I can use the old one that be great too
PS3 stick compatibility on PS4 is on a per-game basis, done by the developer. So if whatever game you want to play (I’m presuming MK11?) supports legacy controllers, then it might work, depending on the PCB that’s in the PS3 stick.
Just like what our Gunpla friend said, or if you want an universal compatibility, you can either change the PCB or use a PS3 to PS4 adapters too.
Great! Thank you so much for the info
