Hi! I tried search function with several keywords and didn't find anything so that's the reason I made this thread. I have old 3ds xl with fw 4.3.0-10E and I haven't done a single update on it. I bought gateway 3ds (blue and red card) and installed it succesfully and played with it for approximately 7 months. Not too long ago I bought Acekard 2 for old DS game backups and played those with no problem of any sort. This is the first time after using Acekard I'm using the gateway red card to play my backups for 3ds games, but my 3ds isn't reading the card. When I turn 3ds on it shows the gamecart spot empty if the red card is in 3ds, but normal 3ds games do read and show on the spot when inserted (including Acekard2). I've tried to clean my 3ds, red card and memory card but to no avail. Is the red card broken or is there somesort different problem? If you guys could help or guide to right place I would appreciate it!
