Multi controllers on retroarch

Hi there: I have an iPad Air 2 and used retroarch for long time. for that I like it so much. Well, is there any method to play 2 PS3 or ps4 controllers on retroarch like play crash team racing on it? Specially I saw on settings on retroarch there is 4 controller ready to mapping but I don’t how to connect two controllers on it. So please help me. i saw this video but it didn’t works with me

Well I have two PS3 controllers and ready to play them but never connected together.

Other thing: when the new update will come with XMB support (v1.2 or so)? The repo on cydia is breakdown.so if the update is already come how we can download it? Forget about the nightly versions it has some issues so I’m waiting for official version

Thanks a lot

Official 1.2.* release isn’t out yet. When it’s ready, we’ll set up a new cydia repo and post the location for everyone to use.

Sorry, I don’t know anything about pairing multiple controllers in iOS.

Thanks hunterk for replaying. well does anyone know how to connect multiple controllers on iOS like on video above please?
