Nope. Your eyes are playing tricks on you, as I was approaching 4,000, not 5,000. :^_^:

As of now, my favorite hack is Super Mario Bros 3 Mix, look it up guys, its FUCKING AMAZING! New powerups, Yoshi, without lag may I add, and so much more! Its awesome, got great difficulty scaling and much more than that. Seriously, if you have never played it, get it NOW!
