I only did about 2 hours of SRing for the one-who-will-not-be-blue Giratina the past 2 days, all because of Okami xD. After today, I will be off until 12 p.m. on Sunday, so I'll be SRing for Giratina while I'm off and hopefully it'll shine soon.
My other targets have also remained untouched, seeing as I'm trying to get up to Celadon City in FireRed 2 so I can begin SRing for a shiny Eevee. I have many from chaining, but it'll be my first shiny Eevee by SRing when I get it. I'll also be getting back to Regirock in Emerald and hope it'll shine.
Congrats on your new shinies guys. Come to me shiny Giratina!
