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.
