So yesterday I was playing Pokemon Platinum (Official Cart) on my DS Lite. Managing some Pokemon in PC boxes, when all of a sudden the 'Sort' button on the touch screen was activating itself. At this point, I (honestly) thought I was psychic. But then after exiting the box, I couldn't use the touch screen to change apps on the Poketch. After 5 seconds of this, my DS Lite shut off. I tried turning it back on and nothing happened. I thought it was bricked. I took out the battery, 5 minutes later, nothing. I put in my EZ IV, held the B button and BAM! It worked! I have no idea what happened, and I haven't found a way to re-enact it. So what could've been the problem? Something internal or could the firmware have been messing up.
