Nintendo r4 nor working

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

Make sure you bought the correct R4 for the DS light and not the DSi. If you bought the correct one, then it sounds like the R4 cartridge is defective and needs to be exchanged for another one. Remember, Nintendo does not support the R4 cartridge, so go back to where you purchased it from.

hi, i had this prolem with r4 sdhc card red menu when i put on r4 card software on ds lite. solution put on r41 software works fine now , hope this helps

had the same problem if you can get an r4 card you no works copy entire contents over to your card then delete ther games and add yours but keep there kernal . dont forget to format your card b4 copying ther card

After some Googling, here's a suggestion from a forum (http://forums.afterdawn.com/thread_view.cfm/696944): try adding a paper spacer to the top (side without contacts) of the R4 and then inserting it into DS. On the forum it was the older DS that it didn't work with, but it might just be that the newer ones have been used more.

Hope this works!

Did you download the R4 files directly to the root menu of the card? If not you can find easy to follow tutorials on google. Good luck

u have to download the kernel from the website your r4 has

Try the "fix" posted above by Guest, I've had that work for me in several different cases.
