Please post your information or corrections as a reply to this thread. This post will be updated from time to time to add to the map!
Note: Credit for a large part of this data goes to ScarletCoils--previously known as DahrkDaiz.
Terminology: $ denotes a ram address in hex, 0x denotes a ROM address in the .nes file

$300~$350 = PPU Buffer. The buffer works as follows. $300 is the current size of the
buffer. $301 and beyond is data for the PPU in the following format: AA AA SS XX XX XX 00
AA = address of PPU to write to, this is written in big endian format.

When writing to the buffer, always end it with 00 and update the buffer size.

This byte is also used to draw the P-Meter. Each bit depicts the tile type. There
are 8 tiles [|>|>|>|>|>|>(p)] the (p) is two tiles. Lets say $3DD were 0000 0101 then the
first and 3rd arrow tiles will light up.

$577 = Kuribo Shoe indicator (0 = no shoe, 1 = shoe)
$578 = This is the transformation byte. When Mario gets a power-up or is injured, this
byte contains the power-up he will go to + 1. Thus, if he's going to be small, this
byte is 0x01. A value of 00 means there's no change. A value of 0x80 will give you the shoe.\
$57A = Tanooki's Statue Timer.

another power-up appears, this byte is over written, thus the first power up disappears.

will be added to your main score. $69C = high byte, $69D = low byte
$70A = Current Object Set/Level Type
$711 = Timer used during World/Lives status screen before Mario generates onto

$727 = Current World
$736 = Player 1's Lives Counter
$737 = Player 2's Lives Counter
$73A = This is where the palette for the current level is stored. The palette is loaded
before the level is drawn, so changing this byte doesn't have any effect after the level
$7C1-$7E0 = This is where the palette current stored. Changing this won't have much effect on the
palette. To force a change, set $5E to 0x06
$6000-$794f = This is where the 16x16 block numbers are kept that corresponds directly to
the level. An example is that 0x40 is the value for a coin. This also applies to the map screen.

$7F50-$F52 = Timer tiles (same for score tiles)
$7F9A = Seems to be the start of some buffer. Setting this to anything but 2 will prevent bricks
from animating when broken.

0x3F0-0x3F6 = This is a properties table for power-ups. The bits do the following:
S = Sliding disabled. If this is 1, you can't slide on hills.
F = Flying ability. If this is 1, you can fly.
Each index into the table corresponds to a power-up status. Thus, if you change 0x3F2
to 03 (0000 0011), then Fire Mario (index here is 2, 2 is fire power) will be able to fly
and not be able to slide on hills.
The x's have no effect.

0x14DFA = Sound byte used when Mario goes over a map screen.
0x16190 = Hammer Bros. Item table. Here is a big chunk of 00s and a few bytes that
are not 00. The groups of bytes that are _not_ 00 represent the items you receive from a
Hammer Bros. Examples are the first byte, 09, is world 1's Hammer Bros. item (a star).
Next is 0D0B0C which is world 2's (music box, hammer, whistle) and so on. The item values
are the exact same for the item values listed above. Note, world 8 has NO Hammer Bros. item
groups. Instead, the items in the treasure chests found there are defined by enemy level
data. When using the Help Sprite as a Hammer Bros. the item control is 2 bytes before the
normal Hammer Bros. group for that world. The Airship sprite uses the one after that

bytes that are 02, this is because there are two mushroom pictures in the roulette you can
0x2D721-0x2D732 = N-Spade card matching game initial deck. The deck is always shuffled
from code, so there's only 1 deck you can modify without ASM hacking. The values for each
card is as follows:
00 = Mushroom
01 = Flower
02 = Star
03 = 1-Up
04 = 10 Coins
05 = 20 Coins
0x309B0 = This is the left side of the curtains tile. This must be an even number, then
the tile to the right of this one will be the right side of the curtain. You cannot change
the number of tiles used to draw the curtains without ASM hacking.
0x309D5 = Debug mode activation/deactivation
Activated = 0xCC
Deactivated = 0x35

7 bytes in all, but the 7th byte is 00, you can change this so that you gain an item for
beating world 7. For values, see Global item table.
0x3B14B = Table of items used to create Mushroom House treasure chests.
Some bytes affect the "all same items" mushroom houses. Meaning, if all the chest have
the same items, then only 1 byte is needed to define the chests, rather than 3. The first
5 bytes affect these type of mushroom houses. The 3rd is for all Frogs, 4th is all
Tanooki, 5th is all Hammer. 1st is All Whistles (never seen in the game), 2nd is all
P-Wings (also never seen in the game).I believe these two are used for White Mushroom
houses. The rest are 3 item houses. One type is 0A 0A 0A, all three anchors. This is the
ONLY exception to the same-type house rule. And remember, the definitions come in groups
of three. Example: The second set (bytes 9, 10, and 11) is 01, 02, 03, a set of three
defining the Mushroom, Flower, and Leaf type houses. For item values, see global item table.
