So my friend had an European 3DS that he bought on a trip, I installed A9LH on it. Some time ago he purchased a Pokemon Y cartridge locally that is US, which didn't boot before because of the region. Now it boots and everything, but when he tries to claim a Pokemon serial code (code is compatible with US Pokemon Y Version btw) that was given to him in a local store he is given an error message that the code is invalid. I assumed this had to do with the region and tried launching it through HANS and setting the region to USA, but I get a message preparing to load game and it hangs there. Any ideas on how to claim the code? I've also tried region changing using Luma Region Emulation and nothing. I should note I am using the HANS release included in the starter.zip linked in Plailect's guide. I could probably claim the code on my US 3DS, but I would prefer something he could do of his own since I think he has more than one code.
