I have the following problem: I decrpted my NSMB2.3ds file and I got the romfs folder(that with the stuff in it). I edited a few courses and I make a new RomFs.bin with makerom. I put this into the folder "Decrypted" and I tried to rebuild the rom.But when i tried, at the first try It just doesn´t apply my files.So I copied the romfs.bin to the "encrypted" folder. Now it doesn´t created a -cia at all. How can I now create a .cia file that works?
