Pkmn shiny formula

[stylie25]

Hey peeps.

Just wondering has there been a paste of the formula pokemon UM/USUM uses to determine shiny odds? Both for wild encounters and if possible, SOS chaining and ultra wormholes.

 

I know a lot of people say what the odds are, eg: 1:4096 but am curious where the number actually comes from.

 

Thanks!

This is the formula that is used by the game, to determine if a Pokemon is Shiny.

PID.High xor PID.Low xor TID xor SID < 16
if the returning value is not 0-15, it will not be shiny.

This gives an overall probability of 16/65536 or 1/4096 as standard odds.

Shiny Charm: Basically reroll PID 2 extra times, if the generated PID isn't shiny.
SOS chaining: Between encounter 70 to 255 (after 255, it rolls back to 0), game will reroll the PID a second and a third time.

I'm not aware how Ultra Wormholes roll for standard Pokemon, but it appears for legendary and UBs, they are base odds.
