I spent hours on this one and finally worked it out. I have four kids and the ordeal started when I ordered two R4 cards and they turned out to be different, so I found out lots.
Odds are, you have bought a clone R4 card, not the genuine thing. If it is genuine, you can download the latest software from www.r4ds.cn
. If that doesn't work, you more than likely have a clone.
The genuine R4 card uses encrypted software, so you will never get it to work with the genunine download. Just a well all the clone manufacturers have clone sites with clone software, the trick is to know which one you have and what can work. Here is what I discovered.
Turn the R$ card over and look at green printed circuit board just above the electronic contacts. You may see some white printing.
One of my cards says "R4-SDHC". This means that the R4 card can take a high capacity SD card. There are any number of versions of the software available, try www.r4sdhc.com
. At the time this was written, version 1.32 worked just fine for my card.
The other card says "ROHS CARD-7A". This is not a high capacity card and no software will work with an SD card with higher than 2GB memory. So if you are trying with a 4GB card, like I was, it won't work. For this one, I switched to a 2GB Micro SD card and downloaded "r4team v 1.19" from www.linfoxdomain.com
and it worked fine.
If the above software downloads don't work, there are a stack available on www.linfoxdomain.com
under the Nintendo DS tab, so go with trial and error, and you should eventually get there. Note that It took a few goes with the first card before I found v 1.32 and got there.
So good luck, I feel like I know so much more now.
