Homebrew My app fails to load any files from NitroFS on hardware

nitroFSInit returns true, but fopen always returns NULL. This issue doesn't happen on emulator. Tested on Twilight menu and an Acekard 2i, same results on both.

Are you running fatInitDefault() before nitroFSInit()? With the default devkitPro NitroFS library that breaks on hardware. nitroFSInit() will automatically call fatInitDefault() so it's safe to just remove that.

If you use the alternate NitroFS code (used in TWiLight Menu++, etc) which lets you specify a path to use then you will need to fatInitDefault() before calling it.

I am not calling fatInitDefault, no. And yes, I am using the default devkitPro NitroFS library.

Hmm that's odd... Do you have nitro: in your file paths? (ex. "nitro:/file.txt")

iirc due to the order it initializes the filesystems in no$gba "/file.txt" (no drive specified) will be NitroFS where on hardware it'll be SD.

I was not aware you had to do such a thing! That appears to have fixed it, thank you!
