How do I disable FCEUmm from automaping of cycle through color palette to my left trigger? I have slowmo already mapped to left trigger.
go to quick menu > controls > port 1 controls and scroll down to L2. Use left/right to cycle through functions until you see — (three dashes). That means “nothing”
Ohh my. Now I feel stupid 
heh, no worries dude. I’m glad that got you fixed up.
