If you don't already know, CrystalTile2 is one of the best NDS ROM hacking tools available. It combines the functions of a hex editor, disassembler, tile editor, NITRO filesystem browser, and more into one very versatile and useful tool for any NDS ROM hacker. The program has been mostly translated from Chinese for us English speakers. According to the about window the program was made by a fellow named Crystal and translated by tempers cory1492 and FAST6191. Much thanks to them and anyone else who may have helped in the the creation of this amazing program. That said something odd has been done, seemly intentionally, so that the usual place to get this program is just a circle of redirects. You can try for yourself at this blog post by the person who maintains CrystalTile2. Both the latest version and the second to latest are unavailable as of this writing. I'm not sure why this was done, but as someone who had the chance to use this program I feel compelled to see to it that it remains available to those who want it. So download away. As you're bound to notice this particular version of the program requires a "registration". I'm not entirely sure of the reasoning behind that, but for now at least I won't attempt to provide my copy preregistered. You should be able to register your copy by following the steps below.[*]Run the executable once; it should create a new ini file labeled CrystalTile2.[*]Open said ini and copy the line beginning with "user_id="; this is your unique ID.[*]Paste this line into a new email addressed to wannya*AT*qq.com; title it CrystalTile?? and send.[*]Hopefully you'll get a reply with a new line beginning with "sp=". Copy and paste this into the ini file a line below the user_id line.[*]Run the executable again and it should launch the full program.Please let me know if you get a reply back from the author or not. And should you know what the cause of this download situation is, I'd love to hear that too.
