Vita3k Compatibility (PC): Ingame- does lag while doing fights on the Vita3k. Tested with Vulkan When game first boots there will be a screen with Japanese text and it will not allow you to continue, press the "O" button a few times and it will let you play after. No way of testing this on actual Vita hardware sorry. Does work with Vita3k while installing it as NoNpDm. Lag can be a bit much but it is playable.
I prefer the psp frontier ones, since like others have mentioned at release it was only half of the story.
