So, okay, currently using a Super NT on latest firmware, version 4.9 I think. Well, so I turn on the console, and up till this point, the SD2SNES has been running flawlessly, but not today, all I get is a black screen, so I turned the console off, reseated the cart and SD card, and it turned on fine. But this time, it asks me to enter the time/date, something that it hasn't done in all the time I owned it. Okay, I thought, nothing to be worried about, so I play a game, then I go back to the Super NT menu, load Super Turrican 2 then the SD2SNES again. Well, this time, it asks me to enter the date for a second time, I'm thinking the SRAM batter is either dying or the cart itself is dying. I mean, yes, I did get secondhand from a friend, at a discount, but damn, I don't know what it means in all honesty.

Edit: May be a battery that needs to be replaced but since I don't want to spend money for that or a soldering iron, ugh.
