I cant play any ds games on my ds because it wont read ds games

ask for another one

your friend destroyed your game, you need to start a new game, it will only work with an Action replay

Well you need to call Nintendo Inc. and send them your game, then just only use an Action Replay 20 times then through it out of it will mess up your game or even your DS.

well when using cheats it always has a chance of corrupting your game

an action replay i something you shuld NOT use constantly, because it will start to effect the normal functions of the ds

The ds lite or the pokemon diamon game might of been damaged before u got them

I dont know how this worked but for me i had loaded every single cheat at once, that seemed to be the problem. once i put down only one or two cheats it worked fine.also know that some cheats are scams and wont harm your ds game but make the screen turn white and unable to load. be careful if you get the walk anywhere cheat you could get lost and the game would crash. to activate most cheats you press L+R but for some it is different and it will tell you what to do. my favorite cheat is this one:

94000130 fdff0000
b21c4d28 00000000
b0000004 00000000
94000130 feff0000
00000890 01ed0001
d0000000 00000000
da000000 00000892
dc000000 00024620
c0000000 0000000b
d7000000 00000000
dc000000 00000006
d2000000 00000000
it allows you to obtain 493 master balls. if you wanted a mew you would throw out 342 masterballs then hold L while walking in grass. i got 342 by subtracting 151 (mews number) from 493. the pokemon will be the level of the surronding pokemon in the grass. good luck and hope this helps

You have a bad cheat or a wrong cheat enabled. That is why it's not working. Just disable that cheat and it should work fine.

Umm i think you can manually add it on check on youtube or Google or ask me personally :]

Do you know anyone else who has a nintendo ds (doesn't have to be lite)? If so, try the game in that sytstem, and if the same thing happens, then the game has a glitch. This tends to happen a lot with plenty of my handheld games, and i find that it helps if you blow into the game cartridge, and also into the cartridge hole. If that doesn't work, try repeatedly turning the game on and off. And if that doesn't work, try going to nintendo.com.
