Support for >4GB romfs images on FAT32

[OatmealDome]

Feature Request

What feature are you suggesting?

Overview:

• The romfs of some games can exceed 4GB in size. For example, Splatoon 2's romfs with the 3.1.0 update is approx. 4.9GB large.
• A romfs.bin file for these games cannot be stored on FAT32 partitions.

Smaller Details:

• Related TODO in fsmitm_service.cpp?
• Possible file layouts:
  • romfs.bin, romfs1.bin, etc?
  • raw_romfs/00, raw_romfs/01, etc?

Nature of Request:

• Change

What component do you feel this would best fit within?

• Stratosphère
  • fs.mitm

Why would this feature be useful?

Would allow users to avoid the buggy Horizon exFAT driver when working with large games.

Just use Horizon OS's large file support (i.e. folder with archive bit set, and files inside named 0, 1, 2, etc)

I had no idea that was a thing you could do. Thanks.

@OatmealDome libnx got support for creating these files with fsdevCreateFile recently, too.

Have you tried making a standard archive? a folder named romfs.bin with archive bit set that contains splits named 00, 01, etc of max size 4294901760 bytes edit: got ninja'd while i was looking up the exact size 😅
