R4: An error has occured

Hey there,

Do you have the original R4 card? It's possible that your DS isn't recognising it because the original one (before the R4i and R4 SDHC came out etc) only accepts up to 2GB Micro-SD cards. You should check the size of the Micro-SD card you're using at the moment.

I recommend buying R4i cards / R4i DS cards from either dscardworld.com or nds-gear.com - probably nds-gear if you're in Canada or Europe since their international rates are a bit cheaper

Good luck!

This sounds like a problem with the MicroSD card in the R4. Some brands have been known to be incompatible. Without knowing more information about the R4 and the SD card

A couple of years ago, I had three microSD cards fail, even reformatting failed. I believe it was a problem with the R4's at the time. Try reformatting the microSD card in a PC, download the latest kernel and load that on to the microSD card, if you can get it to format.

Failing that, buy a new SD card. SanDisk/Transcend and Kingston are the preferred and recommended types. Is this an R4 or R4-SDHC? Don't use an SDHC(4gb+) memory card in a R4, only in R4-SDHC.

Memory cards are cheap enough 1gb-2gb don't cost that much, if you have an R4-SDHC then try a 4gb

I take it it was working at some point or other, or is this a new card?

It's a bug issue in the firmware of the R4 cards. Won't work after 14 april 2010 unless you update the firmware of the R4 card.
For the time being you can set back the date before 14 april 2010 and it wil work directly.

Hey there Colin,

The original R4 card only works with Micro-SD cards up to 2GB in size. To use Micro-SD cards up to 32GB, you need to buy the newer R4 SDHC card or a Nintendo DSi comaptible card. Check out R4 Cards / R4 DS Cards from DSCardWorld.com or NDS-Gear.com (NDS-Gear is probably better if you live in Europe or Canada as their shipping's slightly better internationally).

Good luck!

Download the R4 software,
Format the sd card, (copy any games and save files to your computer as a backup)
Copy the R4 software onto the sd card ,

should work fine i did this 3 days ago

could be the card..... sorry my 4gb micro sdHC didnt work on my phone nor games n music for my ds. sorry to big and the r4 isnt compatible with the 8gb sdhc,,, also i mod psps and there way cooler!!!!!!!!!!!!!

The SD card format only goes to 2Gb, anything after this, is an SDHC.  You are obviously trying to use this with an R4 card or similar... These will only accept micro SD, and not micro SDHC

Im not 100% sure about this...I own a R4 myself. What I do notice if you use the wrong type of SD Card(Anything above 2GB) or use it in the wrong type of R4(SDHC Kernel in a Non-SDHC Card) It tends to get stuck at that loading screen.

Sometimes you can remedy this by taking the R4 out and the sd card out and using a air can or blowing on the parts in between(inside the DS, Inside the R4) and try it and it will sometimes fix that. Also a corrupted transfer of the kernel or a bad kernel can do that too.

Hope this helps.

Btw here are a few Kernel Links:
R4DS(Non-SDHC): www.r4ds.cn
R4DS(SDHC): www.r4ds.us

Hope this helps

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.

i had the same problem, my 2 gb would work ok but not my 4gb i have heard that the 4gb wont work on the older r4's, so i bought a ds Lite R4 Revolution III (Version 3) from amazon.co.uk and it came with evrything you need and it worked great the address is https://www.amazon.co.uk/s/ref=nb_ss_w_h_/275-1618189-4849908?url=search-alias%3Daps&field-keywords=DS+Lite+R4+Revolution+III+%28Version+3%29&x=14&y=15
