Re: Black Screen When Trying to Run Using Mega SG

rename the firmware file to [Yourserial]_forced.upd and boot. The megasd led should start blinking, just leave it there till it finishes.

This sounds like the issue wither the MegaSG not loading the cart initially.

The way around this was Run Cartridge, goes to black screen.
Press reset on the MegaSG.
Then open the MegaSG menu and Run Cartridge again.
Usually the second time it would properly load the cart.

Renamed to _forced. The light blinked at varying frequencies for just over a minute. No graphical output during the process. After that time, light was a steady green. Continued leaving it powered on with no controller input for 10 minutes. After that time, I brought up the Mega SG menu and selected Run Cartridge. No change. Powered down, reviewed the filesystem. The update was renamed to [SN]_update.upd. Removed that and created reset.cfg. Reinserted and powered on, this time it powered up to the menu.

Success!

Confirmed the version of the firmware reported and was successfully able to play both a Genesis and a Sega CD game.

Thanks for the assistance.
