Positional Selective Item Max Probability [Vega]
This code will increase the odds of you getting your desired item to 100% based on the P (position in race, see values below) you set in the code. This doesn't guarantee your item, but if the item is available and you are in the correct position you set in this code, you will get your item. Keep in mind that if you are not in the correct position you set in this code, you won't get your desired item even if it is available.
The 'flaw' in this particular code is that you can possibly get an available item in an illegitimate position (Example: P value 1 for 1st Position, Item set to Bull Shell, Blue Shell is available for play, you get Blue in 1st, this is not possible w/o cheats)

How the code works~
When you hit a box, your position is checked
If you are in the correct position, your item probability table is modified for your desired item to it's highest possible value the game allows.
If not in correct position, code simply doesn't execute
