[Coco] Largest sdcard supported by SDC?

I would still recommend a 32GB SDHC card (not SDXC) as the max for use in the SDC,
as >32GB cards are SDXC with the native (default) file system as exFAT, which is not supported.
Presuming you can successfully format it FAT32, it will probably work, but to avoid any
potential issues, I'd just stick to 32GB. As you say, there's not much reason to go larger.
SDHC cards in the 32GB or less range are abundant and cheap.

As you note, the card must be formatted FAT32, so one must reformat the larger cards (Windows tries to keep one from doing it, but you can do it from the command line, and Linux/MacOS is happy to oblige with standard utilities). But, once formatted with something besides xFAT, they work (assuming the code accessing the FAT filesystem isn't broken in some way, as the FAT32 specification supports sizes up to 2TB).

But, I got tired of people asking for the maximum size the hardware would handle, and lamenting it was *ONLY* 32GB. Once I tested 128GB and suggested anything larger would also work, those "checkoff" questions disappeared. This suggests to me that no one else was seriously considering using a > 32GB card, but they wanted something to complain about).
