You can eliminate the
Create 'ncchinfo.bin' file steps if you do this.
Grab a copy of
boot9.bin and place it in the root of your
3DS Simple CIA Converter v5.0 folder. Once you have that in place, you put your *.3ds roms in the
roms folder and press
Convert 3DS ROM to CIA button. It'll then ask you to select a folder. You can press
Select Folder if you're already in
roms even if you don't see your .3ds files.
To read more about how to -or- where to obtain the
boot9.bin, this was mentioned in back in page #37 starting around post #
728 to the last few current posts.
