I don't know, may be list hard-code in psv?
If psn support restore backup to psv it will support.
Eg Final fantasy VIII, Super robot taisen series.

I disagree with this idea.
DATA.PSP start 0x150 have 0x410 bytes unknown data,  I fill random data here, it doesn't effect game run.
and some pocketstation supported game release on psn before psv release.
eg ff8 pkg download from psn file date is Wed, 07 Oct 2009 08:39:01 GMT
