I couldn't really type earlier since my phone is having screen issues (makes it hard to type and see what I'm typing).
But I had the 3D & the wireless turned off
I had SSFIV running (system closed in idle) while it was charging and I took the 3DS out to wait at Best Buy for Black Friday (complete waste of time... there was a family there ever since 8am on Monday morning). After about maybe 15-30 minutes of SSFIV, I switch it to SM3D land and spend maybe an hour, probably less, beating the 1st 3 worlds (I am on 4-1 now) before the red light starts flashing.
Is something wrong with my 3DS?
and no I do not know what my brightness settings were at.
