Sorry, posted this thread on the wrong place before so I post it here again: Hi, I have modded a Multimega with Multi-Bios and I removed the crappy sound board and installed a MegaAmp instead. Now the console plays every game and the sound is beautiful... Except that I now have a very annoying buzzing noise. The sound was so bad before that it's difficult to tell if it was already there before. But I tried multiple power sources with different amps/volts output and scart cables that were all top notch quality (from retrogamingcables), but the buzzing sound is always the same. At low volume it's ok but when I push a little bit it's buzzing like hell. It's even worse when using a Mega Everdrive. Once the music of the game starts it's ok, but when there is no sound/music it's there and it's very annoying. I noticed that the copper ground shield inside the Multimega was gone, can it be the cause of the sound noise? Please help, nothing is more annoying than a console with a buzzing sound!
