http://reiforce.deviantart.com/art/Stardew-Valley-RWBY-Yang-641350821 I made these via a request after someone said my style reminded me of Stardew Valley. I've never played it, but I want to make it so that these can be swapped out with a character. I'd still need to make the map sprites and junk, but I'd be willing to do that. The only info I can see about modding involves messing around with the game files and swapping stuff. I don't have the game, so is there a way to just make them available for everyone?
It's easy enough to replace one character's sprite / portrait with yours. Once you get the game and can mess around in the directory, it's actually quite straightforward. There are two folders exclusively for the sprite and portrait. There's (by default) no background, so if you really want to replace a character that has to be deleted. Get the game though! It's excellent and XNB modding just looks harder than it really is.
