Super Mario Bros.: World 9

This hack expands the original game with a 9th world.

Features:

* Bowser and Peach can be found in World 9.
* In World 8, the new fake Bowser's real character is the red flying Cheep-Cheep.
* World 9 takes place at night like World 3 and 6.
* All levels of this world have checkpoint, except World 9-3 (established technical reason).
* Time is 400 seconds in every level.
* It can be selectable on the title screen after beating the game.

NOTE: Due to not having a regular World 9 (like in SMB2J), this world was created as World 8-6, 8-7, 8-8 and 8-9 as 8-5 is automatically ignored by the game. Moreover, bonus rooms and hard-only enemies were planned, but didn't work, so that's why these are all left out.
