3dsxtool
Imported from https://github.com/devkitPro/3dstools
Used to convert ARM ELF executables into 3DSX, for running in emulators and on consoles.
artool
Converts any binary resource (including text files) directly into ARM ELF Objects. Key word here is directly. Instead of converting the binary code into a C/ASM array like bin2c and bin2s, artool uses libelf to directly embed the binary data into an object file for linking.
