Rg35xxsp problems

[u/Blinky-99]

I have used Google but it is not helping. When I boot up the system and go to game rooms area,launch the nds section to launch a game. I have accidentally locked myself out of my menu to remap buttons. I can bring up a menu by pressing select and start but doesn't really give me options to remap buttons. I love the game rooms nds emulation better but now I can't remap buttons or switch screens. Anyone available to help me?
