Is it like HG/SS where it's determined once you beat the E4, or is it like the birds in platinum where you have to talk to a person to re-release them?
When you beat the E4. But it's basically impossible to RNG abuse it there. You have to hit the right IV frame after the Elite 4, but battling advances the frame at a rate of 120 frames per second. At the very least, you will need to battle the Champion.
90% of shinies look worse than their original form, 9% hardly look different at all, .5% could go either way.
