Not reading ds card or game pack. Even though both are inserted into ds

If you are inserting a DS card, be sure there are no foreign articles inside the slot. Blow into the DS card slot to clear any debris. Also be sure you are inserting the card all the way in until it clicks. I've also found that if you're powering on a game, and you bump, grasp or touch the ds card as the DS is powering on, that can cause it to not read games.

Check the actual DS card itself and carefully look at the exposed contacts on the circuit board. Be sure none of them are scratched, damaged or otherwise. A scratch can damage a contact, thus preventing proper data read.

If anything was spilled onto the DS card, be sure it is thoroughly cleaned with a damp cloth (no cleeaning chemicals!) If you immerse the DS card, or pour liquids on it, that may damage it as well.

Same points hold true for inserting a Gameboy Advance game (if you have a DS or a DS Lite. The DSi and DSiXL do not have Gameboy Advance slots.

If you turn on the DS and nothing happens, try a different DS Card. If it only happens with that one particular game (or games) your DS cards are damaged or need cleaning. If all your games are not playing, there is a problem with your DS. Try your games in a friend's DS just to make sure. You'll probably have to send the unit to Nintendo for repair, or take it to an authorized repair center.

The game is just checking if there is in the slot 2 socket a addon card placed, like a rumble pack or a extended memory pack for the ds browser.

A Game Pack is the game cartridge you insert to play a game. GameBoy Advance Games are not compatable with the Transfer Pak. The Transfer pack and Pokemon Stadium 2 only support the following: Pokemon Red, Blue, Yellow, Gold, Silver and Crystal versions. No Ruby will not work with the transfer pak as you will not be able to insert it, and the software would not pick it up.

hang about its even reckonising the card? let alone booting into the menu? sure you dont have a duff card? i had 2 of those, sent em back got replacements that work brill.

well if thats the problematic case,

if it says no game inserted and theres a game in the slot,
this reallt worked
1 turn the ds off
2 take out the ds game
3 turn on the ds(remeber the game is out of the slot)
4 turn off the ds
5 carefully blow on the ds game all around
6 then blow in the slot were the ds game goes.
7 now put the ds game back into the slot.
8 now finaly trun on the ds and it should say theres a game in the slot

Try plugging the memory card into your computer and checking that the files still exist. It is possible to delete files from the memory card whilst it is plugged into your DS.

HTH

Try eject, blow into the port then reinsert. There is a possibility that your ds has blocked the r4 from being used on that ds.

remove game card and place ds in warm place overnight ...damp is causing this problem

have a good blow where you insert your card, if it still doesnt work take it back for a replacement, you dont need to set up any settings what so ever

Take the game out then blow really hard into the game slot. Re-insert game - it should work :-)
