NOTE #1:

00 = small
01 = big
02 = Flying-Cape
03 = Fireflower
04 = small & invincible
06 = victory pose when falling
09 = sort of "dancing" Mario ("burnt Mario" when falling)
1F = ?
2F = Swimming animation
FF = "sad" animation when falling????

NOTE #2:
Mario will automatically run foreward at a quite unusual speed for a Mario-game.
Be careful not to bump into a wall or anything, else Mario will get smashed due to the velocity - well, after all he ain't Sonic the Hedgehog! ;)

NOTE #3:
This modifies Mario's vertical position.
E.g. XXXXXXXX = 00001300 sometimes is near the ending of the level.

You should activate the code before you enter the level, else the graphics won't be 100% error-free.
However, if the value is to high, you will be placed "outside" the level and you'll instantly die.

NOTE #4:
When you free Yoshi in the specific level, Mario will start to look like Yoshi himself! Until you free him, Mario looks like a graphic-error.



NOTE #5:
xx = 00 - nothing
xx = 01 - mushroom
xx = 02 - fireflower
xx = 03 - star
xx = 04 - feather
xx = 05 - 1up
xx = 06 - climb;
It works as if it would be a levelmodifier; you can sporn lots of climbs in the air (always above Mario) and they will remain there! By doing so, you can climb them up!
xx = 07 - boom?
xx = 08 - rising platform
xx = 09 - ?don't know?
xx = 1e - Rugby-player
xx = 26 - fire-sea-roses-thingys
xx = 27 - unknown enemy(?)
xx = 29 - hammer bros.
xx = 2a - Gumba (maybe Para-Gumba)
xx = 2b - spinning (and hurting) thing
xx = 2c - Bullet (enemy)
xx = 2d - thunder and darkness!!
xx = 2f - enemy (looks weired)
xx = 30 - spinning thing to stand on
xx = 31 - some enemy
... (I didn't check any further.)
