If swapping out the cartridges in your Nintendo DS Lite is enough to give you the fits, then you may be an ideal candidate for the NDS Lite Game Selector. It’s a simple $13.42 adapter that adheres to the back of your NDS Lite and holds three game cartridges at once.
When you’ve grown bored of whatever game you’re playing, a simple flick of the switch on the game selector will load up one of the remaining two cartridges. It’ll save precious time when you’re right in the middle of a game-playing brouhaha.
Even better, it makes travelling with your three favorite games less cumbersome and may keep you from losing them between the car seats. And at less than $15, it’s not a huge expense as far as portable video game accessories go.
