I've had this problem before with my DS the way to fix it is to blow into the part where you put the DS game and put it in if that does not work get a new DS, DS Lite, or DSI.
The game ID for a Nintendo DS game can be found on the cartridge. There will be a code, which is specific for each DS game.
on the back of the ds game there will be a few letters or numbers that is the game id
You put the game name on and then put the game Id
On the front of the DS game card, near the bottom will be the game ID.
you should insert the game you want to enter and then write down the id code then you put the action replay back into the ds and at the top it says 'add new game' select it, then type in the name of the game and then the id number. that's what i do
what is the game id for guitar hero on tour for ds
The Game Id Is B4BEN0J08
it will say you have no game inserted and you will be able to type in the code at the bottom of the ds game. NOT THE DS! the GAME!
The Game ID isA6FE-1EBED497
The ID in a DS game for Action Replay DS is letting it know what the game really is. A good site to get game IDs is www.neoseeker.com I use this site all the time.
The Game ID can be found on the front of the Game Card, at the bottom, below the small picture of the game.
go to buy it at market
