Special thanks to:
Mewn (odds and ends)
EspioKaos (quests)
Tycho (matter board, various UI bits)
EDIT: 4/23/12-very minor fixes. Spacing on unique boss designations e.g Vibe DragonVol Dragon (thanks Vashyron for actually managing to find two), a few enemy names (Karonga->Garonga, to help the people who can read katakana, a few consistency things), and Recovery Pot->Recovery Pod (because really).
Original message:
There's been a bit of a setback for the complete dissection (they reworked ice file headers, at the very least), but the following has been found so far:
Main UI texture (cropped because the top half is still blank).
Item small icons. Note the CV fleshy clothes (they change the second color; unclear what it'll mean for the selectable colors) and like a bajillion weapons.
Text strings:
Dewman (yes, it's actually referenced outside the character creator now). Actual text for its name appears to be "-" right now, so yeah. Someone found a reference to "beast" in with the others, but I can't really confirm if it means anything (it appears to be placed wrong; everything has dewman fourth, but that has beast fourth and dewman fifth).
Classes: 17 slots (00-16). 17 also exists, but it's "All classes" (for equipment data).
0491: DesertBossNew. I can only assume this means they decided that 0490 wasn't good enough, and totally remade it.
enemy/en_rappy_helloween.ice, enemy/en_rappy_easter.ice, enemy/en_rappy_santa.ice. Seasonal monsters? Oh yes.
Photon Blasts: 4 categories, 3 each.
Photon arts: 7 per weapon type are available (2 yet to be released).
I have the text file that has the PA, enemy, NPC, etc names in it, I'll dump it to a .txt in a bit and upload it.
EDIT: Aaaand... done! Here it is.
Most immediately relevant: The four PB creatures are ヘリクス (Helix; nonstandard spelling, potentially Heracles/Hercules), アイアス (Aias; nonstandard spelling, Ajax), ケートス (Ketos, Cetus), and ユリウス (Julius). Each has three attacks (shared): プロイ (proi, "morning"), イメラ (imera, day), ニフタ (nykta, night).
Yes. PBs are named in Greek. This is the most awesome PS ever.
