I haven't had this Super SD System 3 for very long, but the games have been mostly playable. However, when attempting to launch Bishoujo Senshi Sailor Moon, rather than seeing the usual BIOS screen before the game loads, I just saw "Loading..." in the same font used elsewhere in the UI. It stayed like that for a while. Once I realized that the Loading screen was never going to go away, I turned my system off. When I turned it back on, my games weren't showing up and there were some weird green shapes on the screen. These shapes appeared both with and without the microSD card inserted. I put the card in my PC and discovered that ALL 188GB of games had been deleted. The only thing remaining was an empty "bup" folder. This is a brand new Sandisk 256GB microSD card. I'm using a US version Turbografx-16.
Before I spend several days re-downloading everything, I want to find out how to stop this same thing from happening again. If there is a game file that the Super SD System 3 doesn't like for whatever reason, there should be a failsafe that simply boots back to the main menu after a specified length of time. The correct error handling method for this shouldn't be to erase all my games.
