Because Fire Emblem is notorious for trying to update sneakily I inadvertently updated to 9.0.1. Now I have 2 memory cards one of which has 35 hours of play data, is almost the exact same as the second memory card but gives a black screen upon launching Kosmos… I now have bought a 3rd memory card to transfer all the data but gold-leaf won't install any of the updates/auxillary battles and because of this it won't let me play my old data. Is there anything I can do?
