In general, this is not true.  On another platform, I offer a similar 
product, and I tested a 128GB card in it, which worked fine.  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).

I tested the same card with the CoCoSDC.  128GB works fine, in my 
limited testing.

(And no, I don't see a logical reason to buy such a large card for any 
classic platform, as I am not aware of any platform library that large. 
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).
