Graphical Item Warning Online

Works Online only.

This code will place a graphical image on the bottom on your screen saying "ALERT!" whenever someone is holding an item (in inventory) that you have chosen in the code to monitor.

XX Value = Item to Monitor

XX Values:
00 = Green Shell
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 = Bullet Bill
10 = Triple Greens
11 = Triple Reds
12 = Triple Nanas
14 = Nothing / No Item Available

NOTE: This code makes use of the following memory addresses...
0x81660000 thru 0x8166002F
0x81670000 thru 0x81670003

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