The following article is a RAM map for Super Mario Kart.
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
