Recalbox supports Bluetooth ps3 controllers since the first version. What is not supported right now but will be in 4.1 is the internal Bluetooth of the rpi 3.
So if you are talking about Bluetooth :

And you need a bt dongle whatever the rpi version you have.
If you are talking about USB, recalbox do not officially support it.
