I don't know if anyone else has ever had this problem, but I just popped in my copy of Hover Strike, but upon getting to the menu and pressing B to load, I'm asked to select a difficulty, as if the game has no save data stored (I was on the Level 4 missions). So I soft reset, and tried again, to the same effect. Then I hard reset, same again. Assuming that the Eeprom had failed, or at least had an error and deleted the data, I played a mission and saved, then soft reset. Back to having no data. So I took the cart out and put it back in again, powered up again and hit load, and there is my save file again, on Level 4! I assume there was something that was blocking the pin connectors, but has anyone had something like this happen before?
