Heyo all. Haven't seen an English guide for this yet, so I thought I'd make one up while I'm free at work. I'll update this with pictures and download links when I get home, but a list of steps is fine for now.
Update 1: Still at work. However, I have not tried this with CIA version. If you are editing saves for the CIA installed version of Or/As or X/Y, please do so at your own risk.
Update 2: Reworded some parts for a better understanding.
Update 3: Added some links, cant add pictures until I get home
Update 4: Realized I cant upload pictures, instead updated what I could with more concrete info
What you'll need right off the bat:
3ds on 4.1-4.5 with Gateway 2.6
Pokemon game in Gateway, Original game cart wont work
DevMenu to install cia's (Not telling you how to do this, enough guides as is)
PKHeX - Newest version (11-22-14 as of writing) supports OR/AS (Link: http://projectpokemon.org/forums/showthread.php?36986-PKHeX-(Gen-6-SAV-PKX-Editor))
1: Download Python 2.7. You'll need it if you dont have savedatafiler.cia installed.
Link: https://www.python.org/download/releases/2.7/
2: If you dont have savedatafiler.cia installed already, you'll need it to get your OR/AS save file and import it. Dont bother looking for a download link for it. Trust me, its not easy. Youll need to get the 3ds sdk, which isnt hard to find, and convert the savedatafiler.csu from a csu to a cia, which can be done using this: http://www.maxconsole.com/maxcon_forums/threads/285574-3DS-To-CIA-Converter
3. The directions for that program are pretty simple, so moving on, install savedatafiler using DevMenu's cia installer
4. Once installed, open OR/AS or X/Y in Gateway's menu so it appears on your home screen in the gamecard slot, but dont start the game.
5. Open Savedatafiler
6. Go to CTR-CARD, should be the first option, this is your emulated game card, in this case, your pokemon game.
7. Simply hovering over CTR-CARD, press Y to export the save data to your sd card.
7.5. Shut off your 3ds
8. Take out your big SD card and put in computer
9. Under the folder "filer" in your big sd card should be a several folders, and the most recent one is the one you just exported, and within that should be a folder called something like, "000011c4", and within that folder is the "main" file. This is your save that will be edited. Make a backup of this file just in case.
10. Open the "main" file in PKHeX by going to file, open, and changing the file type to all files, and edit it to your heart's content.
(FYI, right clicking in the right panel after you open your save will let you edit that box pokemon. Just letting you know cause I had trouble figuring that out.)
11. Once finished editing, go to the SAV section on the right pane, and hit export sav. It says it'll save as a cybersave file, but its the same as the file you took from your card.
12. Move the "main" file that you edited back to the folder you took it from.
13. Disconnect your SD card from the pc and put back into 3ds
14. In emunand, open OR/AS or X/Y again as you did before, without actually starting the game, and then open savedatafiler.
15. Go to the sd card pane on the right and import the save following the instructions on the top screen.
16. If completed successfully, you're good to go. Go to home and start up your pokemon game of choice with edits galore.
17. ???
18. Profit.
Will update as needed, getting off work in an hour.
