@mitu I apologize. I didnt know. I just ordered it with ready to play out of the box. Then I updated from source to get the newest version of everything. I didnt realize that against license or whatever. My apologies.
Everything works perfect except killer instinct and I'm just trying to change the emulator it uses to see if I can find one that works better. I guess Ill try another forum not directly associated with retropie.
Thanks
