Super Mario Bros. 3: RussianMan's Super Mario Bros. 3 Hack

This is a short unnamed Super Mario Bros. 3 hack (RussianMan) made. It's only 2 worlds long. This is a sort of experimental one. First world features vanilla elements, while second world features new enemies and stuff.

Do note that it's very difficult, for experienced players.

-I had to cut level 1-6 because of conflict with 1-4 (constantly messes with sprites). I grew tired of it, so i just placed a level ender. Maybe i placed too many sprites in either level, but i don't think redesigning either of them is worth it.
-Koopalings display wrong graphics for the wand, using power-up sprites. I have no idea what caused this and i don't care. I already spend too much time fixing stuff.
-The hack ends after you beat 2-Airship, you can't do anything on the letter screen, requiring reset.
-APPLY .BPS PATCH TO PRG1 USA SMB3 ROM!!! By using Flips.
-Tip: in level 2, if you walk off the ledge with kuribo shoe, you'll be able to jump in midair.

Some credits i didn't fit in the game:
