Error message when loading Mario Kart in DS

Have fixed this on the DSi by deleting the Mario Kart DS file using the Action Replay DSi Code Manager software. Under MY CODELISTS on right hand pane create a new file by clicking NEW then right click ADD NEW GAME type in both game code and game ID e.g. ACMP E45A2937 for Mario Kart DS. Right click Mario Kart DS and select add new cheat. The cheat codes can be copy and pasted in here.
Drag and drop the file from the right hand side to the left hand side of the window so that it appears in the memory card list. Press COMMIT CHANGES to save.

well, it depends what game u r playing, but just google search (The game you play here) then put game id so ex: (mario kart is example game) Mario Kart Ds Action Replay Game ID

Try an another access point.

These three characters are owned by three different companies.
Though as some arcade game players might know, Tamagotchi was in a Mario Kart Arcade 2 game. But these machines can be really had to find.
I'd suggest finding a real Tamagotchi toy or finding the old Game Boy Color Tamagotchi game as these follow the original pet simulation formula.
The Tamagotchi games for the DS are all mini game collections with Tamagotchi themed things.

As for Cooking mama,
theres
Cooking Mama 1
Cooking Mama 2
Gardening Mama (released last month or so)
Plus two Gardening Mama games for the Wii.

For Mario I'd sugget;
New Super Mario Bros
Super Mario 64 DS
Mario Kart DS

You can pick these all up from your local game shop for a decent price or better these days.

Tamagotchi can be hard to find, though some gameshops will carry older games.

I hope that helps. Good luck.

Well... My advise is to return the game and switch it with new one!

look at the brass connectors, are they dirty? that could cause a problem

First, it depends on what game it is, NOT ALL GAMES have a DS Download feature.

If you are using a game with the DS Download feature, have the host DS set up the game, this would just be going through the multiplayer then DS Download function.

Next, make sure you both are in the same area (10 or so feet), basically if you can be in the DS Chat with your Local Wireless Connection, you can use your DS Download feature.

While the host DS is sending the signal, the other DS will have a feature in the main DS menu (If you have auto-start on, hold start while starting up the DS and going past the warning screen), it will be called DS Download Play.

Have the person receiving the signal click that option and their DS will search for any games being sent in the general area. Then all the person with the receiving DS has to do is click the icon and he/she will connect with the hosting DS.

The receiving DS will not keep the game on the hardrive on the DS, but he/she will be able to play with you; your best bet however is to get a second cartridge, but that part is your call.

Well maybe when you turn it on, it might be on manual mode. To switch it to auto mode, Press options then press the wrench and then find auto or manual mode and then, switch it to auto mode. Save the options and then it should play the game. If it doesn't work, blow into the DS game and then the DS game slot.
