Offset	Size	Description
0x0	0x4	Magic "CRR0"
0x4	0x4	Reserved
0x8	0x4	Must be zero
0xC	0x4	Must be zero
0x10	0x10	?
0x20	0x20	?
0x40	0x100	RSA-2048 modulo
0x140	0x100	RSA-2048 signature signed by Nintendo, starting at offset 0x20 with size 0x120
0x240	0x100	RSA-2048 signature verified with the above modulo, over the data starting at 0x340 with the size from 0x358
0x340	0x4	Process UniqueID<<8, from the ProgramID
0x344	0x4	Size of the whole CRR0 file
0x348	0x8	?
0x350	0x4	Size of header, always 0x360
0x354	0x4	Total hashes in the hash-table
0x358	0x4	Offset to the plain region containing text tags, from the process NCCH
0x35C	0x4	Size of plain region
0x360		SHA-256 hash-table

Each hash stored in the hash-table is over the corresponding executable CRO0 hash-table.

CRR0 files are usually stored under "romfs:/.crr/". The end of the file is aligned to a 0x1000-byte boundary with 0xCC bytes.

-CRR0 files are usually stored under "romfs:/.crr/". The end of the file is aligned to a 0x1000-byte boundary with 0xCC bytes, however the beginning of the padding is the first two text tags from the process [[NCCH#CXI|NCCH]] plain region.
