Homebrew Upgraded SD card, unlaunch error: empty mbr entry

[lazyguy]

Used guiformat to format a 64gb microsd to fat32.
Not sure what to do, I know people are using >32gb sd cards on dsi, I've seen posts of people saying they've done it.
I check and my microsd card is indeed in mbr.

Your card is probably using GPT partition scheme instead of MBR, I believe you'll need to use Disk Management to change that instead of guiformat on Windows. this guide for converting looks to be right I think

i already mentioned it was mbr
anyways, i fixed it by using rufus to format and it worked. Not sure why guiformat didn't work.
