About This File
After about 18 months of referencing this site and using the user contributed saves, I finally found a way I could give back. This is a pack of 17 save files for Y version, each set in a different region and subregion that corresponds to a particular Vivillon pattern. Each file is progressed up to the point where you can breed pokemon at the day care, and a male and female vivillon at Lv.12. Most files come complete with a fletchinder for quicker hatching and the parent vivillons already in the daycare with an egg ready for pickup. If you don't see fletchinder, open the Polar save file and take it from there. You'll also see the fruits of my Gen 6 EGG RNG labor there, as well.
It's important to note that on top of playing through the intro 17 times (thank god for fast forward) I also had to make sure the regions were set correctly. If you're playing on emulator, this gets tricky. Set your emulator to the correct major region of the game. For 12 of these, that will be USA/ North America. The others require you to set the emulator to EUR, and if you're playing on console, you need to have a EUR/PAL 3DS. (Be sure to check the region/subregion of the parent vivillons& trainer info. These regions are what you'll want to set your Emulator/3DS to for compatibility. For example, the Meadow save file requires the 3DS/Emulator to be EUR, and the region/subregion is Italy/Liguria.
The following 5 will require you to set your emulator to EUR:
Garden
Meadow
Monsoon
River
Tundra.
The tricky part comes in when you need to set the subregion.
On Citra, subregion can't be set via emulator settings. It needs to be set by a 3DS system settings application. In order to use all 17 of these save files to their fullest, you will most likely need both a USA and EUR 3DS or their corresponding system settings apps. This is why the Elegant pattern is not here, because I do not have a japanese 3DS to derive the correct region from. I hope this helps!
