Ds does not registar sd card randomly but problem is reocuring more frequently???

Stuck on Loading Screen This usually indicates that the software kernel on the micro sd memory card has become corrupted. It can also happen if the micro sd memory card is overloaded with games, music and video files etc. The solution is to reinstall the kernel software on the micro sd card and ensure the micro sd memory card is not overloaded. Leave about 25% memory free.
download SDformatter and format the sd card with that, place all the files on there, none in folders..

• Download the correct software kernel from the manufacturers website
• Unzip the files using a suitable programme such as Win Zip or 7 Zip.
• Open the folder containing the unzipped files and copy the 4 files (Moonmemo, Moonshl2, R4iMenu and R4.dat) to the root of the memory card.
• At this point put the memory card into your R4 card. Start your console and ensure the R4 card is operating correctly.
• You may have to run an upgrade file at this point

The camera uses SD memory cards. SD cards max out at 2GB. SDHC cards run from 4GB up, but they cannot be used in SD devices. SD cards can be used in SDHC devices.

The short answer is 2GB.

It sounds like you need to figure out exactly what kind of DS card you have. Check out NintendoDSCard.com's DS Card Setup Guide which should sort you out.

Also, I recommend only buying genuine cards since a lot of the fakes tend to break quite easily. Maybe from dscardworld.com or from nds-gear.com if you're in Canada/Europe since their international shipping's a bit cheaper

Good luck!

ummmm u need to have an sd card this is a AAC
then put it in your dsi slot on the right then now read the steps

1.go to settings
2.go on data managemen
3.select sd card
4.click on your game

the normal ds does work with the original ds, i have 3. lol. the r4 cart goes in the top of the ds in slot 1, it obviously about the same size as the r4 cart, have ur ds so it facinf downwards to the ground, and insert the game facing upwards so you can see the r4 wording on it, slot all way in until it clicks in, then power up.

First have you determined if you exceeded the Memory Capacity for the SD card? If so load SD into your computer Memory card Reader slot, It should pop up on the Screen. Look for Options to View, or Edit the SD card, you should be able to open the Memory stuff and delete some of the games. It sounds like you overloaded the Memory Card.

you can download free r4ds games at www.romsite.com...
dun ever copy games from rom to rom

I use to have similar problems with my DS Card :(. In the end, I end up buying a new one - I personally use http://www.NDS-Gear.com

Apparently, the Sd/tf message occurs when there is a problem with the connection between the micro SD and the DS Card or between the DS card and the DS. You can try giving your micro SD a good clean ( give it a good blow) and see if that makes any difference. Also, I heard that sticking some papers at the back of the DS Card works for some people. If nne of this work, you would robably want to buy a new one or try and get a repalcement from your seller.

It is possible, can be the following:
The card slots from recent nintendo's have been adjusted to avoid the use of r4ds. If your nintendo is newer you can try to put a small pice of carton behind the r4ds card in order to push it well against the contacts.

Have you installed Moonshell onto the micro-SD card? It has to be there to see the games. If you have Moonshell installed, you should be able to navigate to where you stored your files. Your adapter should have come with a CD with Moonshell on it or you can download a newer version on the internet.
