Hacking Upgrading MicroSD after CFW

[kaylapuppy]

I just completed the CFW upgrade using the guide at 3ds.guide. Everything went smoothly.
My question is this. I current;y have a 32 Gb microsd, and wanted to upgrade to 64 or 128.
What size will the 3ds support, and is it as simple as just transferring everything from one card to the other ?

Thanks in advance for any help.

Some have used up to 256GB without a problem and 64-128GB is commonly used. Just do a regular file copy from the old to the new and pop it in.

Adding to what @cracker said.
(1) If you are upgrading to a 64 GB card, make sure to format it as FAT32 and cluster/allocation size of 32 KB.

(2) If you're upgrading to a 128 GB card, first try formatting it to FAT32 and cluster size of 32 KB. Check that themes with Anemone3DS, load times, VC GBA games, nds-bootstrap, etc. works.

- If you find that Home Menu loads up too slow, your game stutters during play, and/or your Virtual Console GBA games have graphical glitch, copy everything off your card again. Reformat the 128 GB card with FAT32 and 64 KB. Copy everything back onto the SD card. The homebrew devs will not recommend 64 KB as it supposedly breaks compatibility with certain apps, so just keep this in mind.

Thanks for that info. I will definitely make note of those settings when formatting the new card.

Also, Windows won't let you format SD cards that are =>64GB to FAT32, you need to use guiformat for that.
