Nitro Explorer has hit version 1.2! If you haven't heard of it (Most likely you haven't), it is a NDS ROM explorer that allows you to extract and replace files currently in the ROM, despite size! As seen with NDSTop System, one cannot replace a file that differs in size, and NDSTool/DSLazy is a little complicated due to command prompt usage, and it also tends to not compile ROMs right no matter what you do (Try New Super Mario Brothers). This however, has been tested with several ROMs, and works amazingly. Also, it has LZSS/LZ77 compression support so you can edit compressed files with ease. http://treeki.googlepages.com/nitroexplorer1.2.zip Note: This cannot modify ROM file structure (Move files location in ROM, add/delete files). Also, it requires VB Runtimes. This program is made by internet guy Treeki, permission was given to post it.
