Hi sorry if there is an obvious guide or something I must have missed it. Please kindly point me to it. I need to convert .3ds->.cia back to .3ds as I have lost my original .3ds, I am thinking if it is possible to use the repacked .cia to recreate the .3ds. Secondly, those dev tools (e.g. SDK-6.2.0\DevMenu.cia) came in .cia format and those are not installable, is there a way to repack them with null key? Thank you!
