Hello all, I've decided to reformat my current 128GB (SDXC) SD card and change the cluster size to see if it will fix some performance issues I've been having with my CFW. I am aware of the potential issues with custom themes and VC games that can result from changing the cluster size, but would still like to do so anyways. I wanted confirm if the process for reformatting the only card currently being used is the same process for upgrading from one SD card to another.

To my knowledge (and from what I've read on this website and others) I would copy the current files on the card to a separate PC folder, reformat the card with guiformat/whatever tool, and then paste the files back onto the newly reformatted card? Or would I need to insert the reformatted empty SD card into the 3DS before pasting the pre-formatted card files back in?

It's been a few years since I've messed with SD cards on my CFW systems so I want to confirm the steps I take are the right ones to avoid ruining files or the device; I apologize in advance if this is a silly/obvious question.

Copy the data off the SD card to a computer then format the card, then copy data back, changing the cluster would increase the size of files on the SD card but also improve the boot time a little. You may as well h2testw the card empty if you never tested it.

You have to format it with Rufus because the default disk formatter for windows only supports 32gb

    @BigOnYa well, starting with, idk which emulator should i use for switch, i got a gtx 1650, do you know which one would it better for my pc?
  • BigOnYa @ BigOnYa:
    The switch emulators on pc rely on your CPU mostly, and they only use a single core, so GPU not as important as a good CPU. I don't use switch emulator, but many here do, and willing to help.
  • BigOnYa @ BigOnYa:
    @K3Nv2 do you want to chime in, don't you use yuzu or ryujinx? Which do you prefer?
  • BigOnYa @ BigOnYa:
    @Morganna I'd say try them both, and see which work better for your setup, good luck, and have fun!
  • Morganna @ Morganna:
    i tried just yuzu so far, not even played, just open the game to see if it run
