I am just wondering if there is a PID calculator application? One that properly checks against the ID/Secret ID's and IV's of the Pokemon. I know that PID is calculated for shiney pokemon using a formula and those value. The math is a bit too much for my head to wrap around. I plan on re-starting my game save but I want to find a combination of ID/Secret ID so that I would have a legal PID for all the combinations that I might use.
Essentially, the application needs to you to be able to select: species, gender, pokemon ability, and nature to calculate all the possible PID combos that would work. Also, you would be able to plug your ID/Secret ID in to confirm if it would be shiny or to list all the shiney PID's for that ID/Secret ID combo. Finally, it should allow you to plug in an PID and get all the values back.
