This is a DLDI file for the R4 created by Chism. It is recommended over the offcial version as this modifies the ARM7. However since the R4 has Auto-DLDI Patching you will need to use DLDI No-Patch to get rid of the "magic cookie" so the R4 can't overide it. You can get it here, http://www.mediafire.com/download.php?nndn1byndez Make sure you DLDI Patch the file first before you use this tool on a Homebrew!
