So, I have an R4 Upgrade III (supports SDHC) and I was wondering what is the best firmware to use on it. I want to play Bowser's Inside story for instance. Is YSMenu possible? I read a guide on installing YSmenu on clones but I don't know what clone this cart is. Is it a DSTT clone? If it's possible to install YSmenu, what's the best way? Guide? I'm not much into this, so I will appreciate a little help. Thank's in advance.
