>>54408687Draw your sprite on a 96x96 canvas, upscale it to 288x288 so that the game can recognize it (and so you don't get weird mini-pixels), name your sprite [headnumber.bodynumber].png, and save it into the custom battlers folder.
Once you boot up the game it'll automatically index it to the correct folder.
If you wanna get it into the official download of the game that gets advertised to people then you gotta go to the Infinite Fusion discord and go through the process to become a spriter.
