I know this topic has been talked about in the past, but from what I could gather the threads are a few years old.
From what I understand there is no technical limitation within SDHC that prevents card sizes of greater than 32GB. Originally the SDHC standard was supposed to officially support 64 GB, but that got moved to the SDXC standard. Since the technical limit of SDHC is the same as that announced as the official limit for SDXC which is 2TB, the differences appear to be software.
According to sdcard.org : "If an SDXC memory card is inserted into a computer or device that does not support the SDXC standard, a message may prompt you to format the card. Do not format the SDXC memory card in a non-compatible device because it will erase the data on the SDXC memory card and format the card for a different file system, making it incompatible with SDXC devices."
This implies that it is not only possible for an SDXC device to read even an SD card, but an SD card can read an SDXC card. However, because of difference in formatting, the SDXC card could be formatted as an SD card making it an SD card. If an SDXC card can be turned into an SD card then that means it's all a matter of software.
I am aware that at one time the Wii could not read SDHC cards, but through softmods it eventually became possible even before it was possible officially and this was all possible because the differences between SD and SDHC are software differences. Assuming the same holds true for SDHX (which all that I can find points to) does this mean it would be possible to eventually have unofficial support for SDXC cards on the Wii?
Currently there are a number of emulators that work from the SD card slot, but not from the USB card slot. With current SD limits of 128 GB and an eventual limit of 2 TB this kind of change would make it possible to store everything one would need on a single SD card for just about everything the average user needs. It would mean that for programs like DIOS MIOS a single SD card is all anyone would need for any number of GC games and would make integration with a USB Loader for USB wii games a viable option.
So are there any groups working on this, or thinking of working on this? What would even be needed to make something like this work?
