I had 3 batteries on my DS and some electical tape: about 20 hours (which is enough for the wait and the flight) if I did it correctly. I would have grabbed my little screwdriver instead of using tape but as the idiot virus seems to be exacerbated by flying I decided against it.
Flash cart: goes without saying.
Headphones: while I might find the tetris music borderline hypnotic I am fairly sure others do not.
Light is usually OK for playing so no need for anything there anymore.
Stylus (and spare): rooting around below seats because you dropped one is no fun.
wilddenim, that rule applies everywhere in the world. It applies to any device capable of transmitting a radio signal, which includes the nintendo ds and everything on that list. But if you can turn the signal off, (or not switch the wireless feature on) you'll be fine. But all of those things are not allowed during takeoff/landing, but during the rest of the flight you'll be fine.
Agreed, while the official Nintendo DS headphones aren't that bad, nothing can beat some nice quality headphones. Also bringing some extra batteries along as well is always helpful in those occurances where flights are delayed, rerouted, ect and your not close to a power outlet.
Hmm, I wonder, do different head phones have different amount of power consumption? If o, wouldn't really good, hi def, noise canceling head phones require more power and drain the power faster? Also I am curious to see the power consumption of using head phones compared to playing the sound through the NDS speakers. I wonder which method drains the battery faster.
Bring headphones for sure. They probably do not take up too much battery power as compared to the integrated ds speakers. Bringing a charger is also a good idea. When you're low on battery, go to the bathroom and drop a deuce
