The only difference between an SDHC and an SDXC is that SDXC runs the exFAT file system, whereas SDHC runs FAT32. Windows tries to prevent you from formatting any SDXC card into FAT32, so you have to use a special tool called fat32format to do the job, which is downloadable here FAT32Format.zip

1.Extract fat32format to somewhere easily accessible, such as the C:.

2.Connect your Micro SDXC card to your computer with an USB adapter. You should not need a special adapter, most SDHC ones will work fine.

3. Open a command line in admin mode. You can do this by going to start, typing cmd, then pushing ctrl + shift + enter. A UAC popup will ask if you want to run it, click yes.

4. Type CD /D C:\ or CD /D e.g. so if you put it in E:\folder1 type CD /D E:\folder1.

5. Type fat32format so if your SDXC is your F: drive type fat32format f:
6.(beware, this will erase all data on the sdxc card, so backup beforehand if needed) Push y then enter when it ask you if you really want to format.
6a. If it says something else is accessing the sdxc card, download process explorer Process Explorer run it, push ctrl + F, type in the drive of the SDXC card so in this example F: and push enter. It will show you what processes are accessing your SDXC card. Close them out and retry step 6.

It should look like this when it runs successfully.

7. Congrats, your SDXC card will now work on your SDHC flashcart/devices. Now install the firmware needed for your flashcard and put the NDS files of your choice on it and try it out. Enjoy!!

This has been confirmed to work so far on supercard DSTWO, EZ Vi, R4i Gold Plus and R4i Gold 3DS. There is no reason it should not work on any SDHC compliant flash card.

I think it's funny when people don't trim their ROMs... I trim my ROMs myself, even GB and GBC ROMs. It makes a difference in the small amount of space you get on a 32MB NOR flash. I can usually squeeze in 3 or 4 more ROMs thanks to the extra waste being trimmed off. I shaved a few gigabytes of room off of my DS ROM collection by trimming. They all load fine from my emulators and flash carts, so I don't see why more people don't trim their ROMs. Complaining that Pokemon Black and White is 512MB (When trimmed, is only 280MB) is just plain stupidity on their part.

I also trim every rom.

Well you could fill up 2TB with a DSTwo if you had a ton of videos in avi/xvid format (720x480 or so). The full Stargate SG-1 is just a bit over 100GB so throw on a bunch of long running TV shows like Law and Order, Star Trek (all of them), the full Stargate series (SG1, Atlantis, and even Universe), NCIS, and so on and you could do it.

If you converted it down to 192X256 (DS resolution) the space it would take up could be reduced by about a factor of 4.

Really though, by the time you'd have 2TB micro SDXC cards, you would probably have 3DS ROMs on it, which apparently will reach 8GB. Given that ROM size seems to go up over the lifetime of a system, and assuming the 3DS continues to be successful, I imagine the full set of 3DS ROMs will exceed 2TB.

after formating does this still work on a 3DS to download and store games from the eshop?

As far as I know, yes.

For anyone with this issue finding the cmd too difficult to use, here's a GUI version of fat32formatter. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

I apologize for bringing up this really old thread. I just wanted to point out that I use my black Wii (2009 model I guess) with Sandisk 32GB microSDHC with SD adapter. I haven't had any problems with loading wbfs files from this FAT32 formatted card.

Very interesting. I am confused though. Because in this Wii tutorial https://gbatemp.net/threads/how-to-...wii-gamecube-and-wiiware-games.360687/page-20 , people said only 2GB is sufficient for Wii?! Am I missing something?

 

[ParkerSTP]

Would it work with a 2TB one?
I like DS games.

I've tried... I've tried...

 

[DarkRift]

does this work to the new 3ds XL?
