You sure resurrected a dead topic.My M3 burns to NOR and when I try to boot it up, it will go to a"gameboy" screen, then white screen with a low pitched sound. Nothing loads after, what would be the problem? I've tried multiple roms all under the limit, still nothing. I have Version 1.74...
But first off, did you check your rom? I just NORed Mother 3 (fan translation 1.2, save location patch from EZClient, nothing else added) - not only did it work fine, I discovered a heavily hacked save that I'd forgotten about.
