I'm having a hard time telling if a bunch of the game is just untranslated or if I've used the pso2 tweaker wrong. I got the menus and items to work, but now all the rest of the text is in Japanese and it wasn't before. And I'm new so it keeps popping up windows and telling me stuff to do but I can't understand a word of it.
Also I'm fucking lost, since I did the first tutorial mission and some anime girl gave me a story board, and then I had to leave and when it came back it dumped me into what I guess is the main lobby area and I can't find a goddamn thing
How do you guys do it?
All gameplay essential things are translated. The only things that aren't are npc dialogue, some tutorial message stuff, Story mission dialogue and a few other minor things that can't be translated due to how they work or would take a lot more time than the small team has, like npc dialogue.
Once you've started theres a few things to do. In the main lobby, there'll be an NPC named Koffie behind the quest counter, she is the most important NPC and is in charge of unlocking quests. Do all her quests. The way she works is simple. You do the first Arks Quest category quest of an area, this unlocks another arks quest in the same area and a client order from Koffie. Do Koffie's client order to unlock the Free Field version of that area and another client order from Koffie to unlock the next area. You do this until you've unlocked everything you can. Along the way Koffie will have other client orders for unlocking more things, you will want to do every single one of her client orders.
Other NPCs in the lobby have client orders of varying importance. Of note, the class tutor NPCs will have client orders that give you skill points at certain points. As you do more of an NPC's orders, more unlock. Unlocking higher difficulties will also unlock more client orders.
The story board is Ep4's story mode system. You watch cutscenes, do a mission or 2, and get some rewards along the way. If you switch to Ep1-3 story when you're in character select you'll get he matter board which is a bit more involved, requiring you to go hunt specific enemies or see cutscenes in specific areas, but is otherwise similar.
Personally i'd recommend going through Ep1-3's story even if you can't understand it. It's some of the only authored content in the game and can be a lot of fun to play through, even if it doesn't really pick up until halfway through Ep1. The overall beats of Ep1-3's story is also pretty easy to follow as the voice acting and cutscene direction will basically let you intuit the gist of whats going on (this coming from someone who knows 0 Japanese)
I wrote a bunch of tips in the OP, check it out if you haven't.
