Exist this adapter for phones?

[heiwasan]

Heiwasan, I think you don't understood which I mean. I think you understood that I wanna connect a PS2 controller to my phone, but I wanna connect my PS2 in my phone.
I already have an OTG cable and I use my controller USB, the same as I use in my PC.

Owww! Sorry man!! I read again the first post, and you’re right!! Sorry, I misunderstood!! =p

The best solution then:

Yep true, I know you can do it with a PS2 emulator using kainy etc.. apart from that not sure.. I'll Google it, if I find anythin, I'll post for ya.

But to be honest, I’m pretty disappointed with kainy!! It worked well on Xperia Play!! Now, with Xperia ZQ (or ZL), isn’t really working!! The strange thing is that ZQ is much better than Play!! =/
