So I have my emuNAND to 9.0.0-20U and i have my new gateway updated to 2.4b, but why do i keep getting this error after pressing SELECT to display my games. 20% of the time, I am able to get it to work just fine and games work perfectly. Another 20% of the time, I see the ROMS show up on the menu but when i press on them, nothing happens and the card goes non-responsive. and about the remaining 60% of the time, i get the error "MicroSD card not ready." From reading on other threads, it says its still loading so i just have to wait for it all to respond to press SELECT for the games to load up. I just got the gateway a day ago and am wondering if this is a hardware or software issue. I am using a 64GB Sandisk Extreme Plus, formatted in exFat. I've tried other cards and having the same results. I've tried opening other apps like the Nintendo Camera and closing right away to see if it resets anything, and nothing. Has anyone ever came across this issue? i tried google-ing it and seems like there's not much out about this issue. any suggestions? much appreciated for any response.
