Heya... just got my M3 adapter (this one: http://sky2k.com/shop/m3-professional-minisd-p-186.html ) and mini SD card today... I've been working on it for a few hours now, and no matter what I've tried, every .nds game I attempt to load hangs when the loading bar fills up all the way, and it then sits there until I restart my system... any ideas?
did you use the game manager software to write it.. or did you just drag and drop? you gotta use the game manager to write it :P
Also, some games won't start unless you use the "START" button to launch them. Most homebrew requires you to use the START button to launch compared to games. Most games require the A button but START can be used as well
Use these settings: (Trim-Rom, 4xDMA, Software Reset)
another option would be to run it in Safe Mode OR use no settings whatsoever (Normal mode).. it should work. It might be because of it being the "professional" version though.. may not have support for all the games out there
basically drag the update file (updat something) and put it in the root of your media card. When you stick it in your M3 it will ask you if you want to update. do yes, and then remove the file after it has updated (or else you'll keep getting asked if you want to update)
