I know nothing, so I won't feel too embarrassed to ask: Can I patch my PSN copy of War of the Lions on my plain vanilla, unhacked PS Vita? The region code is as American as apple pie.
Nope. Any patches for WotL are for the ISO only, because PSN is a totally different monster. And as far as I know, there is no way to modify a PSN game and have it work on an unmodded console, to begin with; even when the keys to sign software were known and everything was encrypted properly, you still needed custom firmware regardless.
WELL, DARN THE LUCK. DARN!
