I’m running into an issue where, on a brand new install of retroarch stable (1.2.2, compiled from source), keyboard control of the xmb menu works just fine until I download the autoconfig profiles (Online Updater -> Update Autoconfig Profiles") and restart retroarch. At this point, controllers I have plugged in get detected properly but all keyboard input gets ignored (even if I restart with no controllers plugged in). If I remove the autoconfig directory (or rename it) and restart, keyboard input is recognized again. Any ideas?
Try to follow this steps to change the archive confg. http://libretro.com/forums/showthread.php?t=4284&p=30246&viewfull=1#post30246 After configure the key for you use.
