I have the r4 and have tried several different kenel file and i have also tried he paper behind the r4 card but it still says loading and goes no further. Ne ideas????

The DSi has several system updates specifically designed to block flashcarts such as the R4. Check the R4 website to see if they have information on what to do if your DSi has blocked the cart. You might be able to do an update to the R4 to fix it. Another option is to get a different cart that has a work-around built in, such as the "SuperCard DSTwo" which has a small chip inside it that other carts don't have and has a file you can download directly onto the memory card that goes into the cart to update it whenever that happens.

You missed some files when placing them inside of the folders when you open your "Micro SD card".

Go on youtube or somthing and try to search for the files to place on your R4. Or ask a friend and copy his/her whle card to yours.

if ur usin the same sd card for both r4 and r4i you will need differant firmware so it will mean havin to keep swappin the files if u want to play it in both but its only £7 for a 4gb sd card off ebay. r4i does use differant files than the r4

cause DSI is the nintendos attempt to stop R4 card users! see the r4 and GnM cards made nintendo invest in a microsd slot! so try using that card with the dsi instead of the R4 as people now are hacking the micro sd slot to allow any ds rom to be played! faster then th R4 due to the fact that the micro sd is connected right to the motherboard of a ds game slot devices such as R4

To format any drive just insert the memory, right click over your memory drive in My PC window, and there should be an option to Format this drive, formatting will erase all the card contents so make a backup in your computer first.

When you click on "format" a window will appear to chose FAT or FAT32 (try FAT32 first then if not working try FAT), dont have to do nothing on the size option, write a label for the drive if you want, not needed, let Quick Format clear, click on start button and you'll see a proccess bar, when it finish it tell you and you have a formatted drive.

Put the sistem files and one rom to test again in the memory, test it on your DS. Be sure you have the right files for your card, the www.R4ds.cn site only supports R4 cards, not R4 III, R4 SDHC or any fake non R4 hardware.

i have a ndsl r4 ver 3
and had it some time,

they are alittle fussy at times,

But go to www.ndslr4.com download v1.25 English


This should solve the problem or at least ease it,

You may have to power on and off a few times, take the R4 out everytime you do this, but once it works it works well, i have over 165 games on one R4.

You should check if the R4 card is actually R4 SDHC, because the firmware of R4DS is not compatible with it. If it is SDHC, go to this website http://rs320.rapidshare.com/files/140174805/English-1.21.zip to download the firmware for your card. If there are any roms on it, you should save them somewhere else, for you have to format the card first (do this in windows by going to 'this computer', then right-clicking on the SD card from your R4 and then select 'format'. Warning! Never select 'quick format'! This could do damage). Now your card is completely empty. Copy the files you just downloaded and unzipped to the card (5 files; _system_, moonshl, _DS_MENU.DAT, _DS_MENU.INI and _DS_MSHL.NDS). Now put the SD card in the R4 and it should work properly :) I had the same problem, and I have just solved it *grin*. I hope this was useful.

1- If you are using the same card in both cards and only work in the R4 deluxe then your R4 SDHC need different system files to work.

2- If you are using different cards with different system files for each one then the files would be corrupted, download them again from R4 site; or your SD memory need to be formatted to fat32 for your SDHC R4.

Hello Minnie,

The last official firmware for the original R4 was v1.18, the R4 SDHC needed different firmware as it's from a different manufacturer. You need the 1.34 software available from this download page if you have the real black box one: R4 Firmware

That should fix your problems.

when downloading kernal of the latest version ie 1.21 you will only be able to use this software with the updated R4 which is the R4 V2 SC which is has only been released in August 08 in uk. The old R4 wont work and you just get the loading screen. for the old R4 you need the 1.19 version. My kids have different versions as I got them 6 months apart and it took ages to work out why one would work but not the other!
