Equal Item Probability [Vega]
NOTE: Outdated by my single 04 line version in main Codes forum.
This code will make all Item Probabilities exactly equal. Thus creating a Random Item code. It works for all items, any position, in any size room. This code is modifying your item probability table after it is calculated from itemslot.bin and the in-race room size.
