It's working perfectly fine though. ROMs are working great and it's all working perfectly. I simply replaced the F_Core file in the ROOT folder, replaced the System folder, and plugged the M3i into my laptop via that black USB cable. Is this wrong? Is there some reason everyone says I should run the M3GUpdaterPlus_142 file using a DS Lite/DSi first? Also I wanted to load up M3 Sakura not M3 Real. How do I go about installing that?
