    Has it been announced whether the R4 and M3S will be able to use the new 4GB Micro SDHC cards?

    If I remember correctly, the specs on the official R4 site state it should be able to handle 4GB cards...

    but the way HC cards and normal cards arrange their memory is completely different, hence the ability to carry much more memory. i personally doubt the R4 team read so far ahead and predictted how the memory would be stored, and matched their R4 carts accordingly.

    It definietely DOES NOT support SDHC cards. I have one of the recently released SanDisk 4GB MicroSDHC cards and R4 freezes at the loading screen, I assume while its trying unsuccessfully to read from the card. This is very unfortunate, as if the R4's built in loader cannot access a MicroSDHC card to load the OS then it will not be possible for R4 to support these cards through a software update. Assuming R4 adds support in the future, you would need to buy a new device to take advantage of this.

    I don't know why not? The cards should be backwards compatible, and unless supported SDHC the device will not take advantage of the extra features. If running FAT32 there should be no reason why this shouldn't work... Hmm, I'll have to do some research. Do you have any other linkers to test this on? Where did you buy it and how much did it cost you?

    Thanks,

    Thats the thing, SDHC cards are not backwards compatible; the protocol is different. They will only work on a host which supports SDHC. I only have a R4 to test and I can assure you that it does not work, however I have no problems accessing the card with my SDHC compliant card reader or my digital camera (using the supplied MicroSD -> Standard SD adapter). I'm not sure exactly where the card came from, I had a friend send it over from the USA. It cost about US$100 - quite expensive now but I dont see the price staying that high for very long.

    It should work with 4Gb card.
    I havent tested it yet myself but...
    You can get 10-15 times 1GB card(amazon) for the price of one 4GB microSD card.

    So would you like to get 10-15GB or 4GB [​IMG]

    Thought I saw on the R4 website that the device supports 128MB-4GB TF(MicroSD) card.

    There are 4GB MicroSD cards out since I use one on my R4, I don't know what brand it is cause i got it off Amazon as OEM. It was some no name brand but it works good, slow but good.

    4gb micro sd not sdhc?

    i think you mean 4GBit micro sd (512mb).

    i thought micro sd only went up to 2gb, and you need to buy a sdhc for higher (they are on sale at verizon stores right now).

    I think he's right. It's possible to make 4 GB SD-cards which are not SDHC. There are SDHC ones too though...

    I doubt it. I think the whole reason for microSDHC was that the regular microSD format has reached it's limit in terms of memory capacity.

    The only things microSDHCs and regular microSDs have in common are their sizes AFAIK.

    Would a firmware update bring SDHC functionality to the R4DS? (I doubt it somehow)

    An extremely stupid question but I just wanna make sure: is R4DS compatible with Sandisk 2GB Micro SD?

    Q: How many files can I have on the M3DS Simply?
    A: M3DS Simply supports 128MB~4GB SD/TF (MicroSD) card , 4GB=32Gbit.

    Why they state 4GB is beyond me.


    http://www.sdcard.org/sd_memorycard/Simpli...ecification.PDF
    from page 5


    3.3 Card Capacity
    In terms of capacity, two types of SD Memory Cards are defined:

    • Standard Capacity SD Memory Cards supports capacity up to and including 2 G bytes (231 bytes).
    All versions of the Physical Specifications define the Standard Capacity SD Memory Card.
    • High Capacity SD Memory Cards supports capacity more than 2 G bytes (231 bytes) and this version
    of specification limits capacity up to and including 32 GB. High Capacity SD Memory Card is newly
    defined from the Physical Layer Specification Version 2.00.
    Only hosts that are compliant to the Physical Layer Specification version 2.00 or higher and the SD File
    System Specification Ver2.00 can access High Capacity SD Memory Cards. Other hosts fail to initialize
    High Capacity SD Memory Cards (See Figure 3-1).

    Note:
    1. The Part 1 Physical Layer Specification Version 2.00 and Part 2 File System Specification
    Version 2.00 allow Standard Capacity SD Memory Cards to have capacity up to and
    including 2 GB and High Capacity SD Memory Cards to have capacity up to and including
    32 GB. SD Memory Cards with a capacity greater than 32 GB will be available with updated
    versions of Part 1 and Part 2 Specifications.
    2. Hosts that can access (read and/or write) SD Memory Cards with a capacity greater than 2
    GB and up to and including 32 GB, shall also be able to access SD Memory Cards with a
    capacity of 2 GB or less.

    Look at the date of the revision of the document you mention, and the date the press release on M3 was made. That should tell you what you are missing.
