Ah, i use Pokopom so it's just mapped 1 to 1 for a 360 controller (which my PS3 controller thinks it is haha)
Also slightly more on the original topic, True 50/60 FPS we will run into two issues:
1.) the EE of the PS2 (which PCSX2 emulates of course) is most likely not fast enough to run 50/60FPS all the time, resulting in visible slowdowns. Solution is to overclock the EE, but Devs say that if it's even possible, it'll be a pain in the rear and no-one wants to do it.
2.) sound (SPU) is tightly synced to the EE from what i gather, so if you could OC the EE instead of fixing the sound, it would actually speed it up more.
My only possible solution is to make an OC button that doubles the EE speed, and than make an option in SPU to half it's speed, that way hopefully everything for sound it fixed up, Though the more i think, the more i feel you'd have to decouple all the parts of a PS2 to do that, Which i feel that wouldn't actually work.
But i am by no means a programmer, So i'll let a dev be the final word on it. I know it's been kicked around a lot and gone no-where, could just be the lack of 60FPS patches though
For interest on making a true 50/60fps patch, I'd contact VIRGIN KLM, he/she may very well know how to point you in the right direction.
Also look in the widescreen thread, maybe even post, i've seen a few people make 50to60hz patches for Persona 3 and 4, could be the same can be done with FFXII
