I recently purchased a M3i Zero in a game shop in NYC for use with my Nintendo DSi. Unforunately I had already upgraded the firmware of my DSi to the latest official release, 1.4.5U. I was wondering if there was any way I could get the M3i Zero to work. I read that there was a patch for the M3i Zero firmware covering the 1.4.5 NDS firmware but I'm not sure how to go about it. I tried a few options but I'm not sure what versions of F_CORE.DAT and the SYSTEM folders I should be using. Do I have to wait for a new version of M3Sakura or? Sorry, I'm not that educated on this device and thanks in advance for any help. Also, the guy at the shop in NYC mentioned to check out gbatemp..hehe Thanks!
