This thread is to help find out what is causing savegame issues for some people and why not for other people. Now investigations by others have shown that the SaveKeyY might be different between firmwares 4.5 and 5.x/6.3 (latest) and that is causing the savegame issues for people. But here is something I am wondering about: Does a Pokemon X/Y savegame on a retail card work on two different 6.3 systems? Can anyone test this? Here's my theory: if emunand and sysnand are acting like two different systems, then testing with two genuine systems on 6.3 should behave in the same way. So if two genuine systems on 6.3 don't allow reading the savegame from Pokemon, then it makes sense that it doesn't work on emunand and sysnand. Right?
