I didn't know this game even existed, I don't remember any screenshots in magazines of the time nor reviews. Of course, back in the day, Sega Genesis and Super Nintendo were inundated with great games, even licensed ones, and tons and tons of crap coming out every month. It was a great time to be a gamer.
I will have to look into grabbing a copy of this one after seeing some YouTube vids of it in action. It looks really fun and your review paints a picture of a game I need in my collection.
Yes, I didn't know this specific Speedy Gonzales game either, I only knew the "speedy gonzales in los gatos bandidos", which is pretty good too.
