This romhack is fairly easy to patch when a new build is available and to play it on Windows/Android is pretty easy. Unpack the zipped file and then you can play Mario World in widescreen (there's also an extra-wide patch available although I did not use that as I'm specifically interested in this one). Windows - Download [BSNES HD](https://github.com/DerKoun/bsnes-hd) Android - Download [Retro Arch](https://www.retroarch.com/?page=platforms), download the core BSNES-HD Beta, and then go to Video and activate Threaded (and that's it to play SMW but if you use a controller then you'll need to configure it).
