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

 

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,

We cant useing SDHC on Wii, Old Model Digital Carema becuase SDHC was not backward compatiable.

 

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

 

So are there 4GB standard microSD and 4GB microSDHC?

 

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 think theyll release a 4gb non sdhc, when they come out with new chips

 

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.

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.
