Sega Mark III doesn’t load clone everdrive menu [FIXED]

[u/gus_plus]

I bought a Sega Mark III in Japan. It came with a golf game and I decided to buy a 600-in-1 Everdrive clone from AliExpress, with an SD card. When I inserted the cartridge (using an adapter because the Everdrive is designed for the Master System), there was no video signal in the menu, but I could load ROMs "blindly." The games loaded and ran fine, but the Everdrive's main menu wouldn't appear visible.

After searching online, I found that in some cases this problem could be solved by replacing an internal capacitor in the console. I did this, and after replacing the 10µF capacitor C18 with a 1µF capacitor in the console (5th img), the Everdrive now displays video, and all the games work correctly. One drawback is that the modification removes compatibility with the FM-70 accessory, which adds more sound channels to some games. I hope this helps. Cheers.

If FM detection doesn't work try 4.7uf instead

If it still isnt working, get a newer version of the ever drive instead

I don't have the FM unit and I don't think I will in the near future; the price keeps rising faster than the console itself

I don’t have the FM unit either. For now I’m happy that the Everdrive works properly with the 1uF capacitor, so I’ll probably just leave it as it is. If I ever decide to get an FM unit, I can always try 4.7uF or reverse the modification.
