How strange, I am still not able to save after a poke in the game. I checked my new XCX version is 1.0.1E, I use Loadiine (v4+pyGecko) to start the game (in Mii Maker mode) and use TCP Gecko to access money account, I am able to change it "ingame", but impossible to save after this. In other games (Monster Hunter 3 or LEGO City) I even have a SD access error message. But in some others I have no problem with poking and saving. I'll try your XCX next time (but it needs a x64 bits system). Any idea where else I could search ? (I hosts my own files for lkernel and loadiine and loadiine+pygecko, or could TCP gecko be the problem when poking ?)
PS: I have already checked with another SD card... And without poking, the saves ar OK.
