I'm trying to fully test the nn3d I got before I mod it and void the seller's warranty.
I've done everything suggested in this pic. I played the game it came with for like 30 minutes. I then left the device and the game on for a few hours to test the battery and it seemed fine. Charged afterwards perfectly fine as well. Lastly, I booted and played an original ds game in pixel-perfect/not-scaled mode and it also played that without any issues too.
I think I'm probably all good at this point, but I figured I'd at least ask first. Thanks!
