Just my 2₵... I've both heard and read in threads similar to this one that users have reported issues with their systems after formatting (FAT32) an SDXC card bigger than 32GB for use with their 3DS. One particular issue that a forum member mentioned was the overall performance of his/her 3DS being severely degraded with extremely lengthy load times, system boot-up, and intermittent freezing. All the same while, there are apparently users who do this and purportedly have no problems. My takeaway: Nintendo officially states that 32GB SD cards work, no question. Anything other than that, your mileage may/will vary.
That seems to be the case in general, as I've seen reports vary even with normal SD cards, across card (memory) sizes, manufacturers, maybe even classes. Heck, if you just read forums alone, you might come to the conclusion that only the SD card Nintendo includes with the system is guaranteed to work.
Reportedly, MicroSD card adapters may also be a little problematic, but there's also a lot of people who insist MicroSDs work just fine in a 3DS. So, yeah, YMMV.
