I upgraded my firmware (deleted system and pasted the new system) found on this link http://www.m3adapter.com/SLOT-1_Series_M3DS-R.htm I believe it's the official page. The new firmware boots fine but when I go to the game selection screen and I press A it does nothing, obviously I've pressed other buttons and combinations but nothing happens. I even touched it xD. It worked fine with an older firmware but wondering if I installed it wrong or something. Thanks for the help
Go to http://www.linfoxdomain.com/nintendo/ds/ the file you have downloaded is very (very) old, they never update that file. alternative - www.handheldsources.com
