For those of you who don't know, Instacheck is back in a slightly new form, rejoice!

>What is the new Instacheck and where can I get it:
http://projectpokemon.org/forums/showthread.php?37221-%28X-Y%29-KeySAV-Box-Data-Viewer

>Why do I care?
Shinies or easily finding penta/hexaperfects among eggs. If you have your shiny value (SV), someone can get their egg's SV matched to yours. If you hatch that egg, it'll be a shiny.

>Is this Pokégen/can you edit Pokémon files with this?
No.

>Is this hacking?
Eye of the beholder.

>WHAT IF I DON'T HAVE POWERSAVES OR ESHOP EDITION?
Trade someone a Pokémon you caught to get checked.
Eggs: Either ask someone to trade/check 'em or hope for another way.

>Searching the thread, pastebins, SV, hatches:

>I-is there anything else I should know?
- List your Name as your in-game name
- Put your SV in {XXXX} format
- If you have a big list of eggs that you want people to match, PLEASE put it in a pastebin!
- If you need to get your shiny value, trade a Pokémon to someone that can check it.
- Let your hatcher know if you want a nickname, or no nickname, safety reasons
- Make sure your hatcher is aware if it is a gift or you expect it back, though it may be easier to label the ones you want in your post, so they know beforehand
- Label the ones you want back / are holding
- If it hatches as not shiny, press L+R+Start
- It can't be regulated honestly but if the person wanting to get their Pokémon hatched doesn't want you to clone the egg, please respect that. Trust factor, basically.

ALWAYS CTRL+F YOUR SV
ALWAYS CTRL+F THE SV OF POKEMON YOU WANT TO GET AS SHINY
ALWAYS CONTACT THE PERSON THAT HAS AN EGG YOU CAN HATCH AS SHINY
