Another comment taking as base a question on Reddit.

OP had asked if you can swap SD2VITA for a cartridge to trophy-hunt, and also if you can also get trophies for games installed on the SD2VITA.

For both cases, yes.

Only cases I know that you can't is if the save was made by another account, or if you managed to get the console or account banned. And both topics I use as a hook to some kinda lengthy info that could be useful for others:

::: spoiler For saves made in another account, e.g. if you swapped accounts in the console and kept your old saves, or if someone gave his saves to you... Going by my notes as that one I seldom needed to deal with, you can try either synchronizing trophies with the PSN, or using Vita Save Manager.

2018~2019 me had taken note for using Vita Save Manager (calling it VSM for simplicity), but I'd suggest testing it with saves you don't care for first as it's been quite a while and Idk where my Vita is to test it myself.

Anyways, for the steps for VSM, make a manual backup of the saves in case something goes wrong, extract the saves from within VSM, delete all saves from ux0:user/00/savedata/ except the one related to the system mod, open each app but the system ones to create a new save tied to your account, inject the saves with VSM and check if the message about not being able to obtain trophies remains. Past me didn't write what to do if it's still there, so I guess you need to learn to live trophy-less for that game, or start from scratch. :::

::: spoiler As for the other trophy-limiting situation, getting banned... I know only 4 ways that someone could banned on the Vita, hacking trophies, using cheats online, being a d🦆ck online, or using the same account on a PS3 modded with HEN or CFW. Avoiding those, and it should be as safe as it is for hacking a console with third party services but whose provider of those services barely cared for the console for years now.

And if you got banned, best I can suggest is to beg to Sony's support, but if you do, you're on your own. :::
