The prob is i want the jet vehicle form in transformers autobos

Your DS cartridge reader is faulty. Unless you know how to take the DS apart and replace the reader by soldering, you should just buy a new one.

You can play multiplayer games with a Nintendo DS Lite even if you don’t possess a copy of the game. If one of your friends has a multiplayer game card, they can use their Nintendo DS Lite as a host for the game session and you can join the multiplayer game.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); });
Things You'll Need:

• Nintendo DS Lite

Using One Card to Host the Game
1. Step 1 Look on the game’s packaging for the "Multiplayer" icon. If the game requires only one player to have a copy of the game, the icon will show two DS Lites: a DS Lite with a black screen transmitting waves to a DS Lite with a white screen. Below the two DS Lites is a range of numbers which indicates how many players the game can support.
   
2. Step 2 Put the game card in the Nintendo DS Lite that is acting as the host for the multiplayer game session and start it up.
   
3. Step 3 Have the other players turn on their systems. They will use the main menu screen to access the "DS Download Play" icon. They need to tap the icon to begin downloading the game information from the host DS Lite.
   
4. Step 4 Begin playing when all of the systems have finished downloading the game information from the host.
   
Multiple Cards for Multiple Players
5. Step 1 Look at the "Multiplayer" icon. If every player in the game session needs a copy of the game in order to play, the icon will show two DS Lites, both with black screens, transmitting waves toward each other. A range of numbers is under this graphic and indicates how many people can play at one time.
   
6. Step 2 Read the game's instruction manual on how to set up the game session. The steps required vary by company and sometimes by title within the same company.

You never want to play the DS while it's charging, if constsntly persisted it can cause a form of battery leak.

IMPORTANT: Don't charge the DS until it dies on you completely!

When charging the DS the system will display a red light to show it's at its lowest energy, the time it takes to fully charge a DS can take up to 2-3 hours. In the second hour of charging the light will appear green but you don't want to disturb it until the light goes off. ( showing it's energy is full )
