you can't play
no, only on a dsi 3d
Try uninstalling it from your DSi and reinstalling it. If that doesn't work, make sure that you have enough blocks on your DSi to have it on its memory. If you are out of blocks, get a SD card for DSi/Wii online or from a store like Target or Gamestop. That's all the answers I have >,<
Yes, deleting games will free up the space (which the DSi divides into 'blocks') so you've got room for other things. The deleted games can freely be redownloaded from the DSi store.
If you format your dsi everything will erase from your dsi including ur things from your memory card.
It allows you to upload photos you have taken with the Nintendo DSi Camera to Facebook, but blocks all DSi flashcarts. Thaere are fixes for most of these flashcarts, however.
the dsi doesnt take action replays sorry
The screen broke
nothing bad will happen i have a dsi AR and i use it my ds
Nintendo wifi connection treats every DS as a set. If you switch dsi, the points will remain on your old dsi, but the new one will not have any. (This is for security purposes)
Nothing
The DSi has a camera on the inside of the DSi. and one on the outside. There is a program where you can take pictures and manipulate them. It also has slightly larger screens, and can play music. The DSi has a menu similar to the Wii, and has a shop where you can buy games and internet. However, the DSi does not have a GBA slot, and blocks out some illegal game cards.
They haven't made the Action Replay DSi yet. So you have to wait until that happens.
