Country info is presumably stored in this metadata, region-lock is handled by the BOSS module via the programID in the [[SpotPass#Payload Content Header|payload header]].

+Downloaded videos are stored in the SD card [[Extdata]], from the decrypted [[SpotPass]] content payload, adding an additional header to them. Country info is presumably stored in this metadata, region-lock is handled by the BOSS module via the programID in the [[SpotPass#Payload Content Header|payload header]].
-Except for the Title ID, all the values are stored as little-endian.
+While the SpotPass payload uses little-endian, the extra header added to the Extdata is stored in big-endian.
