Thank you for anwseri g steptoe!
I'm Sorry for that, but what's 5G?

I have a PS3 and of course controllers for it, but I like to use the "originals" shape of Controller for each emulator. For example the USB version of NES Controller for NES games and the USB version of N64 controller for N64 games.
There are Bluetooth versions of them too, but these are way more expensive than the USB ones. So my decision is to use the USB ones.
