Keymaping

[jjepic]

Hey, I've been really enjoying onionUI and have been playing some ps1 and gba games. I was wondering if there any key remapping settings for the OnionUI menu. I want to switch A and B and X an Y. If this could be universal it would be great, but i can always change the in game settings via retroarch. I have just not been able to do it for the OnionUI menu. Any help would be appreciated!
