We have an ongoing discussion on that in the topic about a new DS3 driver: https://retropie.org.uk/forum/topic/15967/sony-dualshock-3-call-for-testers-sixaxis-script-module/129 You may want to give this driver a try and remap your controller in Steam Link even if it already is supported - mine was but it had digital triggers, I remapped and triggers became properly analog! Do note that this may not work for libretro cores just because as far as I can tell, no platform emulated on RetroPie supports analog triggers (L2/R2 buttons were digital on PSX).

@Dustin_3487 said in Game freezing issue.: All I see is raspberry pi being sold at multiple websites, a lot of them with games pre installed so I figured they were allowed to do it. That doesn't mean it's legal. You should just ask for a refund.

@sano "When charging, the 4 leds blink together. When charged, they just turn off." okay ..but mine never turn off ...they just keep blinking no matter how long I have it plugged it. "PS3 controllers can't charge from a regular usb adapter. USB charging was not a standard at the time, so they need a driver (or a specific DS3 charger) to negociate and charge." What's a DS3 charger? Could you point to one on ebay or amazon? Right now I'm not worried about getting it to connect to the pi I'm sure I'll have no problems when the time comes to pair it. Thanks for replying!

@dill83 update retropie setup first.

ok I found a solution. If I use 2 ps3 DUALSHOCK3 controller (exactly the same model) everything works well. :) Dani

I've pressed each button on both controllers consecutiveley, yes.
