Super Mario Kart/RAM map

Locations of variables in RAM, for the US version of Super Mario Kart for the Super NES

these were ascertained using bowser on 150cc mode (shouldn't make a difference, though)

Player kart position, 2 bytes unsigned each:

7E1058 = how far south

7E0088 = how far east

So the 'origin' of the map is in the North West (top left)

How many coins, 1 byte unsigned: 7E0E00

Player kart facing angle, 2 bytes unsigned: 7E0095

north = 0

east = 64

south = 128

west = 192

Player kart speed, 2 bytes signed:

speed to the east = 7E1022

speed to the south = 7E1024

Skidding/spin out of control, 2 bytes signed: 7E10AA

Not skidding = 0

Skidding a little to the right = -1 to about -12000

Skidding a little to the left = 1 to about 12000

Spinning out of control = more than about +/- 16500

Items, 2 unsigned bytes:

(7E0D70, 7E0C69)

nothing = (0,60)

mushroom = (0,52)

feather = (1,52)

star = (2,56)

banana = (3,56)

green shell = (4,48)

red shell = (5,52)

coin = (7,56)

lightning = (8,56)

selecting/spinning = (0-8,? )

Height in hop/jump/ramp, 2 bytes unsigned: 7E101F

on ground = 0

above ground = 1+

Status, 1 byte unsigned: 7E10A0 on the ground = 0 jump/hop/ramp = 2 fallen off edge = 4 in lava = 6 in deep water = 8

Surface type, 1 byte unsigned: 7E10AE

unused power up square = 20

deep water = 34

mario circuit road / ghost valley road / used power up square / rainbow road = 64

bowser castle = 68

doughnut plains course = 70

koopa beech sand = 74

choco island track = 76

ghost valley rough bit / bowser castle rough bit / ice = 78

choco island bridges = 80

choco island slightly rough bit of track = 82

mario circuit crud = 84

choco island off road = 86

snow = 88

koopa beech bushes / doughnut plains grass = 90

shallow-water = 92

mud puddle = 94

Gopher attatched to kart: 7E1061

No = 0

Yes = 152 / 153

Mushroom shrunk, unsigned 1 byte: 7E1030

no = 0

yes = 128
