Q: What is this?
A: Sky Army Knife is a multitool for Sky3DS users I'm currently coding in C++ with a dash of .Net. In its current state (version 1.5.1) the tool is capable of generating relatively accurate Template Files for .3DS ROM files, displaying ROM infos of header.bin and *.3DZ files and trimming *.3ds ROM files.
Basically for applying your header to the sky3ds' template file.
