Umm I wasn't actually RNGing my ID/SID for that shiny roamer...
I just searched for shiny frames that's closer to something like 450-550 or something...

For Thundurus, which I did, I think the min PID frame it ends up is somewhere in 450+, if there's no weather after you got out of the house, and you mash the A button.
For Tornadus, it's somewhat higher, 550+ maybe

If you don't mind me asking, when you did it on a cart, did you find out what frame you can hit with the nature you want, then restart your file and RNG your ID/SID to make that frame shiny? That's the method people are suggesting I use.

Just once on a retail.
The other times I did on an emulator.

Hey Emily! Happy Holidays! Have you by any chance RNG'd a shiny Tornadus/Thundurus?

Sure have! Your Entralink RNG guide looks great so far... you sure have come a long way :)

Fine :)
BTW have you been to PokeCheck?
It's like a storage site for your pokes

Hey, how have you been?

Heard you're working on a guide for the new Entralink seed search feature... I'll look forward to reading it! :)

Haha I know... that'd be pretty cool if you could, though :)

You can't turn Rotom into a calculator. xD

It's just my own joke, a made-up thing. xD
