Every ZRIF is hard-coded to a specific Title ID (e.g., PCSE00120 for Persona 4 Golden ). If you paste a ZRIF for the US version into a European game folder ( PCSB00245 ), the verification will fail.
Because 90% of YouTube comments share ZRIF strings for DLC, Updates, or fake Title IDs. If the comment doesn't specify the and Game Version (1.00 vs 1.02) , it will likely fail verification.
