I'm having a problem where there's an audible buzzing noise when using the MegaSD. I haven't had this problem with my Everdrive X3. It's intrusive enough to detract from the enjoyment I've otherwise been having with it.
The Megadrive I'm playing on is a region modded European Megadrive 1, with Packapunch Scart cable and an official SEGA UK power adapter. I've tried on two different TVs and both have the buzzing noise. I'm guessing it might be that the power adapter has gone dodgy but at the moment I don't have any others I can test it with.
Any help would be much appreciated!
