The iiRcade is community is excited that you've made this available to sideload. Thanks! A lot of us are big fans of this game.
We have a .zip file with the iiRcade loading screen artwork and controls pre-configured for iiRcade. Is there some way we can provide it to you? That way, you could post the iiRcade version as a .zip file with artwork and controls ready to go.
