I figured even though this isn't exactly ground breaking I'd post it in order to counter some of the negative focus. So when the game first came out I was a sad sad man because kebindings weren't customizable and all the remappers I used either didn't work or required a restart because they directly modify the registry. I was so so sad and then I updated AutoHotKey to v1.1.15.04 which I can confirm works with Onigiri and as far as I can tell doesn't cause any problems. Not a perfect solution cause there's no way for AHK to know if your typing in chat or actually fighting, though you can always alt+tab and suspend hotkeys, but it's a good compromise if and when they allow for keybind customization. I don't know if I can link the program but just do a google search for AutoHotKey and it should be the first link make sure you get v1.1.14.04 or newer.... Stay away from the experimental v2.0 build.

Now if someone can tell me how to keep Onigiri from locking desktop resolution to what I use in the game I'd be so happy.

try window mode, its not like onigiri has a big immersion effect so there isnt anything lost by playing it windowed
