First you need to get a decrypted ROM.I'm fairly sure this is not the best way to do it, but I haven't found an easier way. I got a decrypted eshop package, as a '.cia'. You'll know that its decrypted if you find the string 'paradise' in the cia file, by doing a a string search in an hex editor. Next, the tools currently available won't be able to extract the rom from the '.cia', or at least, I wasn't able to.(Careful because a lot of 3ds roms floating around are just useless encrypted wastes of spaces ) If its encrypted, you won't find it, as it will be scrambled.

So we need to get our hands dirty and grab an hex editor to cut out the actual ROM from all that junk. You'll need to search for the string 'NCCH', or in bytes 0x4E, 0x43, 0x43, 0x48. That's the header we'll need to locate for the next part.

Since the NCCH header begins 256 bytes before the magic number, with a SHA-256 key, we need to start copying/exporting bytes from the offset of the NCCH header - 0x100. I use Hex Edit, so I just set my mark at the offset of the NCCH header - 0x100, went to the end of the entire file, and pressed CTRL+SHIFT+F9, this selected all the data past the beginning of the NCCH header. #POKEMON REJUVENATION VERSION 10 RESEARCH NOTES HOW TO#ДЄnd then you can either copy paste this into another file, or if you use Hex Edit right click and in the menu click on 'write selection.'.
