This section contains 3DS-related programs for the computer. That is to say, they are not running on the 3DS, but on your PC. Tools, file formats and techniques for editing commercial games are also discussed in GBAtemp's 3DS hacking section which will have additional information. Many tools are useful across systems (a hex editor works much the same regardless of the system you are working on) so do also check out the Filetrip's general programming tools section.
