I don't see any problems there, besides the fact that I'm pretty sure Mystery Dungeon GtF doesn't use Mode 3. You have to use the normal version for any game that doesn't use it.I have both Boot NTR Selector Mode 3 and Boot NTR Selector Enhanced, I did follow guide since I have old nintendo 3DS and I have laters firmware.
Then I get problem show in picture.
What I'm going to do now?
