Yeah, the export ARDS code for Mystery Gifts never seem to work on PokeSav.
You're probably going to need to extract your save file, perhaps using a tool like the NDS Adapter Plus.
On the subject of invalid characters, could you double check \x2018?
Would also like to ask about this Pokemon: http://www.pokecheck.org/?p=detail&uid=747901
It comes from a RNGer I know, got it from him personally so I'm not sure about it.
Shouldn't you be doing more important things too?
Collecting Pokemon can be a hobby to people, such as collecting stamps and other collectibles is to others. Forgive us if your heart of stone refuses to let you see the point of it all.
You are referring to the Mystery Gift files, right? You can get them here.

If you were referring to how to get them onto your game, open your save file in MGE first.
We're legit here. No ROM linkings.
Use a different xdelta patcher if you're getting that error. If you're using xdelta GUI use xdelta UI and vice versa. Hope that works
