To download ROMs and emulators for all systems, go to

To alter the statistics of your characters through hacking into your save 
state (or .zst file), you'll need to go to Break Point Software 
( and download a program called "Hex Workshop." Once 
you're finished downloading and the program is finished running SETUP.EXE 
automatically, open Hex Workshop and use it to open any Star Ocean .zst files 
you may have.

NOTE: This Hacking Guide was designed for use with the ZSNES emulator, and 
was hacked with Break Point Software's Hex Workshop. This guide will not work 
with any other programs, as each one works with the save states differently.  
My favorite version of Hex Workshop is v2.54, as it is easier to use than the 
others, so I recommend you get that version.



Most of the questions I get anymore have to do with offsets - what are they, 
how do I tell what I'm editing, I don't understand hacking in general, etc.  
As far as I am concerned, the Help Section is as thorough is it is going to 
get.  The only way I could explain it any better would be to point at the 
screen and say, "See that there?  That's what you need to change!"  Since I 
can't do that, you'll just have to be on your own if you need any help more 
detailed than what I have included below.

If you REALLY cannot figure out offsets and hacking on your own, read the Hex 
Workshop help file.  For the best explanation (with pictures), open the help 
file and click on the Find tab.  Search for offset, click on the first option 
(there should be four), and click on "How to Hex Edit" in the box below.  
Read over that very carefully, and you should have no trouble with hacking 
and finding offsets after that.  If you STILL do not understand, then odds 
are hacking is, quite seriously, not for you.  If you have reached this stage 
and do not understand, do not e-mail me, for I will not be able to help you.

DO NOT ASK ME TO HACK FILES FOR YOU!  I will ignore any request to do so.


Help!  Answers for commonly asked questions:

You don't use a cartridge in the SNES for this process.  Have you heard of 
emulation?  An emulator is a program on your PC (or Mac) that you can use to 
play the games you have.  First, you need to download an emulator (ZSNES is 
the best, in my opinion) and the Star Ocean ROM.

Once you have both, load up the ROM in your emulator.  If you are using 
ZSNES, press F2 to save the game's state.  This will make a copy of that 
EXACT moment in the game, so when you load the state (F4) it will reappear 
right at that point.  Now that you have a save state file (.zst for ZSNES), 
load up Hex Workshop, load the save state, and hack away!

This can only be done on the computer, when you are using an emulator (like 
ZSNES) and ROMs (in this case, Star Ocean.)  Go to for ROMs, 
emulators, and how to use them.  If you already know, and/or are already 
using an emulator, then move on to the next paragraph.  Otherwise, get them 
so that you can follow the rest of this.

Once you are using an emulator, you may have found out how to use save 
states.  Basically, save states save all the details of your game at that 
exact moment.  Thus, you can use it more often, and faster, than regular 
saving.  For example, if you want to save your state right before making a 
choice (like a fork in the road,) if you choose the wrong path, you can just 
load up your save state and choose again.

At any rate, to begin hacking, go to the Breakpoint software homepage 
( and download a copy of Hex Workshop.  Load up your favorite 
emulator (whatever that may be) and make a save state.  A ZSNES save state 
will have the same name as the ROM, and will have the file extension .zst.  
For ZSNES (the best emulator , in my opinion) press F2 to save a state, and 
F4 to load a state.  Next, load up Hex Workshop and load the save state (ex: 
so.zst)  Use the "Go To" command, which is under the Edit menu, to get to the 
offset you are looking for.  For example, if the offset is 90B4, type 90B4 in 
the "Go To" box and press enter, and it will take you right to it.

Keep in mind that this all uses the hexadecimal system, which means that not 
only is there 0 - 9, but also A - F.  A = 10, B = 11, and so on.  This is 
called hexadecimal because there are 16 numbers instead of ten.

So, let's say that offset 8067 is the offset for guts, and you want guts to 
be at max (255, FF in hexadecimal).  Use "Go To" to go to offset 8067, and 
then type in FF.  Next, save the data, and open the emulator again.  Load the 
state, and voila! the character's guts will be at 255. Note that you can make 
as many changes as you want before reloading the state (not just one, as in 
the example), and that you should close the loaded save file (though not 
necessarily Hex Workshop) before reloading the state.

To find a particular offset easily, use the "Go To" command in the edit menu 
(I think).  Remember, because of the hexadecimal system you can also enter 
letters from A to F.  For example, if the offset is 2041A, use "Go To" and 
type in 2041A.  The program will take you right to it! Also, at the bottom of 
the screen, a small box will say what offset you are currently on (in this 
example, Offset: 2041A).

Now for the entering of values.  Let's say you want to change Ratix's guts to 
99.  To do that, go to the offset that changes guts (8067) and type in two 
numbers (or letters from A to F) that correspond to the value you want.  The 
hexadecimal system is hard to grasp at first.  In the 99 example, 99 become 
63 in hexadecimal form.  In decimal (or standard) form, the base is ten.  
This means that for a number (say 1429) each digit is multiplied by an 
increasing power of ten.  For 1429, it looks like this:

(9*1)+(2*10)+(4*100)+(1*1000) or (9*10^0)+(2*10^1)+(4*10^2)+(1*10^3)

with the carat (^) referring to the power of the number.  If you already know 
how to work with powers, I  apologize for repeating this basic information.  
As you can see, the powers of the digits increase at we go along.  In 
hexadecimal, the base is 16, not 10, so there are a few changes.  Here's what 
1429 would look like in hexadecimal:

(9*1)+(2*16)+(4*256)+(1*4096) or (9*16^0)+(2*16^1)+(4*16^2)+(1*16^3)

Thus, 63 in hexadecimal equals 99 in decimal because (3*1)+(6*16) equals 99.  
The highest number you can get with one offset is 255 (FF in hexadecimal).

Two (or three) offset changes are harder for beginners, because the number 
that you are trying to change is broken up into two pieces.  For these 
numbers, refer to the list of useful numbers after this section.  For 
example, input E703 to get 999 and 0F27 to get 9999.  For example, if you 
want to change your money to 9,999,999, enter 7F in offset E86, 96 in offset 
E87, and 98 in offset E88.


  - For the different offsets, here's a Quick List of the most commonly
used values:  

"14"            for "20"        used for item quantities
"FF"            for "255"       used for levels, statistics
"E7 03"         for "999"       used for MP, Max MP, statistics
"0F 27"         for "9999"      used for HP, Max HP, statistics
"7F 96 98"      for "9,999,999" used for money
"FF E0 F5 05" for "99,999,999" used for experience


NOTE: For the two- or three-column HEX VALUES ("E7 03"), the numbers must
be entered "backward" as shown above to work properly.
    - When saving large numbers to computer language, the order of the hex
values are reversed.  If you open Windows Calculator and enter "999" in
decimal form and convert it to hexadecimal form, it will show "3E7" (note
that Calculator will remove any leading zeros).  To use this multi-column
hex value, add any necessary leading zeros (in this case, in front of the
"3") to make even pairs ("03 E7").  Put the number pairs in reverse order
("E7 03") in the so.zst files.
    - THIS DOES NOT MEAN TO REVERSE THE VALUES!  "03 E7" must be entered
as "E7 03", not "30 7E"!  For the basic rule of thumb, number pairs are
entered like this: #2 #1 (or #3 #2 #1 for very large numbers)


Money: E86, E87, E88
Items: 8BF4 - 8DF3
Item Quantities: 8DF4 - 8FF3

Note: Because Star Ocean has so many items, it had to use a very creative 
system to handle the potentially huge item list.  The item values range from 
00 to FF, with 00 being the empty space, and quantities of 01 (1) to 14 (20).  
However, this only allows access to half the items in the game.  How do you 
get the other half?  Add 80 (in hex) to the item quantities!  Thus, the first 
half of the items have quantities of 01 to 14, while the other half ranges 
from 81 to 94.  For example, the item FF with a quantity of 01 is one 
Hamburger, while FF with a quantity of 81 is one Tri-Emblem.  Also, item 00, 
when given a quantity of 81 to 94, is an item, namely Escargo.

With the Talent offsets, just enter FF FF to have every talent.

Strength, Constitution, Agility, and HP have maximum values of 9999 (0F 27).  
Evade, Intelligence and Stamina have maxes of 1000 (E8 03), and MP has a max 
of 999 (E7 03).  Guts and Level only occupy one offset, so their maximum 
values are 255 (FF).  Gold maxes out at 9,999,999 (7F 96 98), though you can 
set it higher (FF FF FF is the max) if you're trying to buy expensive items 
(such as the Tri-Emblem) and want to spend fewer trips getting them.  Star 
Ocean DOES have 255 levels instead of the usual 99, and because of that the 
max experience you can get is 99,999,999 (FF E0 F5 05).

Skill Points also have a normal maximum of 999.  However, a handy trick is to 
set a character's SP to much more than that (such as 65,535, or FF FF in 
hex).  Even though this number is too large for it all to show, the character 
will still have all of the extra SP.  Since it takes over 6000 SP to master 
every skill, this can save you many trips back and forth to the hex editor, 
which you would have to make if you set your SP to 999 every time.  I do not 
know how the game reacts to these extra points in the long run, though, so if 
you want to be safe I would suggest you return your SP to 999 when you are 
done with upgrading your skills.

Immediately following every stat are two copies of its modified value, namely 
the present modified version and the maximum modified version.  For example, 
Strength is followed by present Attack and maximum Attack.  The reason I did 
not include these values in the offset list is because you cannot change them 
directly through hacking - they are values based on the base stat (in this 
case Strength) and your equipment, and you cannot change the values of the 
equipment.  If you want to change these, either change your equipment or the 
base stat relating to them.  Either way, they aren't important to the guide, 
so I left them out.

The exception to this is HP and MP, where the present and maximum values are 
both important and can be changed independently of the base.  Because there 
are accessories that add to a character's max HP and MP, the game needs to 
keep track of what the original value was in case you take the item off.  If 
you change the max HP/MP to a value that is different from the base, it will 
revert to the base value as soon as you leave that screen, so the best method 
of changing HP/MP is to change all three values (base, max and present) to 
the number you want.  Of course, both HP and MP are maxed out for all 
characters on level 255 anyway, so if you don't want to bother with this, 
just max out your levels.

Yes, equipment does actually take up two offsets in Star Ocean!  This is 
because the game has 511 items total, instead of the usual 255 (or less) that 
most other games have.  Thus, the item values range from 00 00 (an empty 
space) to FF 01 (the Tri-Emblem).

The offsets for the skills are in the same order for every character, but no 
character ever gets all the skills.  For example, fighters cannot get Motor 
Mouth, and spell-casters cannot get combat skills.  Also, you cannot give a 
character Ougi skills that they are not supposed to have.  If you give a 
character skills they aren't allowed to get, they will not appear on the 
skill menu and will have no affect on the game.  To give a character their 
proper Ougi skills, just input a 01 in the appropriate offset (see list
