I never used it to win, I always held back while the others were racing. I'd use red shells and bob-ombs on players who tried to use glitch shortcuts, or I'd go wait at the finish line and give everyone a hard time getting in first place. Everyone had a chance to win, just not the real pro players. I'd also give people thunder clouds, which I took back so people will go faster.
other hackers tho, most would have fun but others uses it to win. I had a few mods, one to go before the count down even finished, one to go super fast, which got me killed a lot, lol.
This hacker one time was using mushrooms only, it was funny. Right when she used a mushroom right at the started I threw a blue shell, hit her with red shells and bob-ombs, after that she played the race normally, lol.
