This delightful ROM hack by Xenowhirl has put Mario universe favourite Yoshi in Sonic 2. But dont for one second think that this is just a simple sprite switch the whole game is functional and has incorporated Yoshi’s famous moves into the title.

As a child there were always two camps in my school playground. Those who took firm sides in the console wars between Sega and Nintendo. These kids would spit on the very mention of a mascot from a rival platform. Then there were the kids who longed to see crossovers. Their love of gaming itched to see Mario meet Sonic and while this was never likely to happen (until many years later and the fall of Sega), ROM hacks like this offer a glimpse of what could have been. However novel they are.
