I have a PS3 controller, now I have a hid modded version of Retroarch thanx to @Flame. My PS3 controller works right away (in the Retroarch menu and some of the cores). No need to change the driver, no need to press any buttons. But when I change the core (for example mame2003-plus_coreA_libretro_wii. dol or Arcade MAME.dol) the controller doesn't work. Neither in the menu nor when I load a rom. So, it is the cores that run the show not retroarch itself (as far as the controller is concerned)?
