I'm trying to fight Ultimate Weapon, but every time I try to use the computer it says "pressure level not confirmed. Reset pressure at level 1." I've tried running back up to the top and resetting everything. What am I doing wrong?

I'm not 100% sure of the question but I think you're talking about the power needed to get down to fight it (Blocks), if that is the case then the power needed for each floor is: 4, 2, 2, 1 (I think anyway).

just use the lowest number in each list and have zell on your team because when you climb down the ladder from level 9 ( i thinkthats the level but im not certian) you come to a big pressure generator
once here zell explain that he was nicked named the machine back home
so he trys to fix it and fails so he punches it and it opens the door and squall says they must have ment fighting machine
contiue through the door and theres a save point to get back to normal party (lose zell i mean if hes not one of you hardest because the fight with ultima weapon is hard unless you use The End)

Reset
Open door to lvl 3 using 2 SP
Then on lvl 3 there'll be another console close to the door to lvl 4
Use 4 SP here to open room to steam chamber
Enter steam chamber (on the left, the door with the zero)
Use the panel here to add 10 SP (you'll now have 17)
Then just go down, use always the lowest possible number (unless it's 0)
You'll have 10 left when you reach the final control panel.

Well that's how I did it. Good luck fighting Ultimate!

i used as little amount of pressure on each floor as possible!!!
and i made it!!!!
with zell in my crew like gelgamesh was sayin!!!
be careful when u get down there aswell because theres some mean monsters there!!!
it helps to have quistis in your crew with her degenerator limit break to save fightin ruby dragons and iron giants!!!

i'll take you from the top:
1-beat bahamut
2-go back 2 ragnarok, and talk 2 party members
3-have zell in party
4-level one use 4 steam units(can't be changed)
5-next level use 2 staem units
6-next level use 2 steam units
7-next level use 1 unit
8-next level use 1 unit
9- let zell handle machine
10-make way down to bottom
11-fiddle with computor. you should have 10 units left
12-battle ULTIMA WEAPON
13-draw GF EDEN
14 use holy war, to make invincible
15-summon all gf's
16-especially use gf's cactaur, shiva and doomtrain
17- pause game if u get stuck
18- when invincibility wears off, use aura on everyone
19- WIN!!!!!!
20-save game imedately after winning

good luck

Thanks everyone, I needed Zell in my party.

There are a couple of ways to go about this:

Solution #1 (Without Zell) Solution #2 (With Zell)
Floor 1:
4 units spent automatically to open door to Floor 2
Total RSP: 16 Floor 1:
4 units spent automatically to open door to Floor 2
Total RSP: 16
Floor 2:
Spend 2 units to open the door to Floor 3: Sector 2
Total RSP: 14 Floor 2:
Spend 1 units to open the door to Floor 3: Sector 3
Total RSP: 15
Floor 3:
Use the monitor on the left under the stairs and spend 4 units to open the Steam Room. Inside the Steam Room you can use the Esuna Draw Point and use the station there to recharge 7 Units for a total of 17 Units. Use teh second station in the main room to spend 1 Unit, and opn the door to Floor 4: Sector 6.
Total RSP: 16 Floor 3:
Use 1 Unit to open the door to Floor 4: Sector 6
Total RSP: 14
Floor 4:
Use 1 Unit to open the door to Floor 5: Sector 9
Total RSP: 15 Floor 4:
Use 1 Unit to open the door to Floor 5: Sector 9
Total RSP: 13
Floor 5:
Use 1 Unit to open the door to Floor 6.
Total RSP: 14 Floor 5:
Use 1 unit to open the door to Floor 6.
Total RSP: 12
Floor 6:
Spend 4 units to open the door into the excavation site.
Total RSP: 10 Floor 6:
Inspect the machinery to the right of the levers, and Zell will suggest that he can handle the machine. Allow him to do so, and the door will open without spending any steam units.
Total RSP: 12


With either solution, you'll be able to reach the bottom floor with the required 10 RSP. Make your way through the excavation site, and at the bottom you'll find another control panel. Save your game at the hidden Save Point and use teh 10 RSP to activate teh final control panel. Inside you'll face a very tough Boss: Ultima Weapon.

Ultima Weapon HP 51,100~160,000 AP 100
EXP - - - -

Ultima Weapon is no pushover. This beast has 1-hit kills and powerful magic spells that attack the entire party simultaneously. You'll have to use every advantage you have in your arsenal to defeat it.
It helps to have the Revive ability on one of your characters. Make sure you have at least one character who can cast magic and ahs the Triple, Aura, Curaga, and Meltdown spells in his/her inventory. Also, try to set everyone up so that they can revive fallen character either with magic, abilities, or items. If you have Squall's Lionheart weapon, it will help out a lot as well.

Start the fight by casting Haste on everyone to give yourself a speed advantage. Then follow that up by summoning Doomtrain or casting Meltdown on Ultima Weapon to cut its defense. Also, make sure you draw the Eden GF before you forget. You would not want to miss obtaining the strongest GF in the game!!

Cast Triple or use Cerberus so that a magic user can heal everyone at once. Follow this up by casting Aura on everyone if you can. By doing so, you can unload on the Boss with constant Limit Breaks. Keep the presure up and Ultima Weapon should fall quickly.

Um you don't need zell if I recall. You can go to a specail room along the way to get more rsp stuff, so zell doesn't have to fiddle with the machine. If you do use zell, there will be alot of battles, very hard ones, like Behemoth and stuff. I continued to die from the enemys untill I did it the other way.

I'm just hear to remind you to NOT forget to draw Eden out.Eden has the longest wait in the game so you can easily tap until you get to the max.Eden does 9999 and has a cool scene.Drawing Eden is the easy part.Surviving the Ultimate weapon is another.All I have to say is "Good Luck!"
