thats just the only explanation I can think of, I was using sxos for a while when chocobos mystery dungeon came out and I couldnt get the cheats to work on sxos, and as soon as I loaded them with edizon instead on atmosphere they all started working. ive seen it mentioned in a few various places on these and other forums that sxos hasnt updated anything in so long and their cheat applet doesnt support a bunch of formats that atmosphere cheats can, something along those lines, and thats why most cheats dont work well with sxos.
