During the last two months I've been playing with a couple of Nintendo's handheld devices. Namely the Nintendo DS lite, PokéWalker and the Nintendo 3DS.
Now, as you may know, the North American Winter this year has been relentless and I commute by foot to work. On my way home from work I would sometimes play on my Nintendo DS lite until my fingers were too numb from the cold to even feel the button presses.
So as I gamed on in the blistering cold night, I noticed something was strange about the game's sprites. They seemed to leave a bit of a ghostly after-image as they moved around in the screen. I wondered if the below freezing temperatures had anything to do with it.
A few weeks later I decided to test it again with the PokéWalker device I had with me. So I attached it my pocket so that it would be exposed to the wind and halfway on my walk back home I took a look at the PokéWalker's screen and voilá! There it was. The pixels on the screen were leaving a noticeable dark shadow as the Pokémon character moved along the screen. In other words, the pixels didn't disappear right away, instead they would fade away.
But what about the Nintendo 3DS? Well, this one is about the effect of direct sunlight on the screen. I noticed that, at least with the Pokémon games, the 3DS reflects the sunlight well enough for me to be able to play it on a low backlight setting. But the 3D effect? The sunlight completely cancels it! The screen shows you both of the 3D images at once when under direct sunlight. It's hilarious!
