PID Rerolling for Encounter Methods 1 and 2
For: Pokemon Emerald 1.0 US
For: Pokemon Emerald 1.0 US
What these routines do is Re-Roll a Pokemon's PID when encountered. The amount of times it rerolls changes with an item as well, in case you want to add an item like a Shiny Charm. I plan on adding a Consumable Item like Mythica Sandwiches that will give a multiplier to these rolls. Both of these values are stored in Temp Vars (8000s). Ultimately giving complete control of the Shiny Rate, without changing any of the Shiny Checking mechanics. So any Shinys that appear will always be an actual Shiny, even when traded to another game due to having PID/TID-SID XOR value of 7 or less. I'll briefly explain the code.
So these routines run right before a Pokemon's PID is generated. The first routine is for Static Encounters, aka Encounter Method 1 (Legendarys, Starters), and the second routine is for standard grass Wild Encounters, aka Encounter Method 2.
So what they both do is run the standard RNG Rolls, generate a PID, then do a quick Shiny check. If the PID is not Shiny, it will Re-Roll a set amount of times. And you can set how many times you want using the temp variables labeled in Disassembled Code. Also, I added an item check, that will increase this amount to a different value, stored in a different temp variable.
Warning, I've only been working on this for a few days, so there may be unforeseen issues. Issues such as abilities that affect encounters. Also there may be a few encounters that won't trigger these routines. For example, I think Fishing uses a different Encounter Mehtod. But anyways they seem to be working great at the moment, so I will share for now and see how it goes.
Default Shiny Odds with these routines:
Standard Rate = 1/4096
Item Boosted Rate = 1/1024

Disassembled Routines and How to Change Odds
Follow these Formulas to Calculate Odds:
To Solve for New Odds, input Rolls:
Odds = 1 - (1 - (1/8192)^Rolls)
To Solve for Rolls, input New Odds:
Rolls = (Log(1 - Odds)) / (Log(1 - 1/8192))
At the bottom of the dissambled code , change the values of the REROLLS (for new standard odds) and REROLLS_ITEMSBOOST (for item boosted odds)
