Get yourself Vita Game Update Checker and check for the game's TitleID to get the link yourself next time; in your case it's "PCSE00383". You can get TitleID from the sticker on the cart (remove the hyphen and type it in the program's uppermost text entry field) or from the URL of the game in question on its PS Store page, in our case: https://store.playstation.com/#!/en-us/ ... LANDS2PSV1
No box, i got it on the vday sale on PSN. Turns out I can get updates for my retail copies of games. But it requires PSN sign in for games transferred via PS3.
I searched, but I couldn't find information on any way other than sniffing through a successful update screen using Charles proxy.
I'll look out for the update checker. Thanks again!
