This pages describes the content of the CFA(titleID 0004001B00010702) RomFS used by NS.

key.bin and value.bin

Originally the filesize for key.bin was 12-bytes, with the 6.0.0-11 title-version this is now 48-bytes.

Originally the filesize for value.bin was 8-bytes, with the 6.0.0-11 title-version this is now 32-bytes.

The two files form a KV-store of compatibility parameters, as follows:

TitleId Name Flags
0004000000032800 Ridge Racer 3D (JPN) Card latency parameter 0x47E000, override level 0

ctr_backup_black_list

This file added with 6.0.0-11 contains the uniqueID blacklist for SD Savedata Backups.

Offset Size Description
0x0 0x4 Total entries, this is value 93 for the 6.0.0-11 title-version.
0x4 0xC All-zero
0x10 Totalentries*4 Entries, each entry is a word in the following format: 0x100000 | title_UniqueID

qtm_black_list

This file was added with title version v4096, for 9.0.0-20/8.1.0-0_New3DS. This is used when launching applications, on New3DS.

The applications in the "blacklist" seem to only be Nintendo-internal (?) test applications, going from the unique IDs (unique ID is (tid >> 8) & 0xFFFFF). Camera mode (unsure) corresponds to stubbed cam command id 0x00410040:

UID Flags
0xF8087 QTM disabled, camera mode 0 [stubbed]
0xF8088 Camera mode 1 [stubbed]
0xF8089 QTM disabled (2), camera mode 1 [stubbed]
0xF8090 Camera mode 0 [stubbed], report app mode as O3DS
