| 0x0 | 0x4 | Magic "CRR0" |
| 0x4 | 0x4 | ? |
| 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 | 0x14 | ? |
| 0x358 | 0x4 | Size of the CRR0 file, excluding padding |
| 0x35C | 0x4 | ? |
| 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, however the beginning of the padding is the first two text tags from the process NCCH plain region.
