I had to take a trip today where I rode in a car for 4 hours. I was looking forward to playing some Meteos on the trip. But when I got in the car and turned on the DS, I suddently realized that since I was in the sun, I could barely see the f**king thing. I looked all over the options for a way to turn off the backlit screen, but never did figure out how. One of the games I rented (SMBDS I think) had an option to turn it off, so I'm pretty sure it's possible, but I'm not sure how without a specific game that gives you the option?
