This code will place a graphical image on the bottom on your screen. The screen will contain the held items (in inventory) of every player in the race. The listing of the items will be ordered by the player slot number. The items presented will be shown in their hex value...

Hex Item Image Values:
00 - Green Shell / No Player on Slot
01 - Red Shell
02 - Banana
03 - Fib
04 - Shroom
05 - Triple Shrooms
06 - Bomb
07 - Blue Shell
08 - Shock
09 - Star
0A - Golden
0B - Mega
0C - Blooper
0D - Pow
0E - TC
0F - Bill
10 - Triple Greens
11 - Triple Reds
12 - Triple Nanas
14 - No Item / No Item Available

NOTE: This code makes use of the following memory addresses...
0x80001500 thru 0x80001518
0x81500000 thru 0x8150002F
0x81510000 thru 0x81510003

Make sure no other codes in your GCT/Cheat-Manager are using those addresses.
