To corroborate that, that infinite stamina code doesn't work for me either on 1.1.0. The infinite heart code does, however. Also I should mention that I was having issues like yours until I downloaded the very latest codehandler and gecko.elf from the githubs.Are you sure this works? It doesn't seem to work for me on 1.1.0 with latest JGecko U. What's worse is I couldn't even get codes I found to work. I found the memory which displayed the number of (fractional) heart's full I had, but when I poked it nothing changed. Same thing with the code above. Can you verify this is working with JGecko U on BOTW 1.1.0? I can't tell if my pokes are even getting through at this point
