Hack description

As the name suggests, this ROM hack replaces Mario with Sonic, with the rest of the game left relatively untouched. Sonic always runs, regardless of whether or not you're holding the B button, all of the texts are changed from Mario to Sonic and Toad now gives you a useful tip.

This ROM hack is an .ips patch file, so you'll need Lunar IPS to apply this patch to your Super Mario Bros. ROM. The patch works for both Europe and Japan/USA regions.
