Version History
------------------------------------
2015 December 23: v. 0.2
-Initial version of this guide. There's still plenty of work ahead but
this is a good beginning :) Added Justin's stats offsets, gold offsets, most of
the items, shoes and jewelry. Still missing other chars' stats, magic, most
weapons and armor.
------------------------------------
This is a save state hacking guide for Grandia, a classic PSX J-RPG
by Game Arts (published by SCEA). Why I bothered writing this stuff? Well...
<insert witty joke here>
So I did fiddle a little with a hexeditor, a diff tool, some save states and
now I want to share it with you, my dear lazy classic RPG gamer. Enjoy :)
PS: This guide won't teach you hex editing. There are plenty of other guides
who'll teach you better than me.
PS2: I used ePSXe. State hacking with ePSXe is a bit tricky but I'll explain
it in detail on section 1.0.
PS3: Use this guide with moderation! You can ruin your fun if you go overboard
and max out everything. In fact, I recommend that you beat the game first
without cheating, and in subsequent replays hexedit away.
Well, on to the guide...

1.0 Save state?
Save state is a file with a snapshot of the game progress on a given
instant. More specifically, its the CPU & Memory data on a given instant. This
guide was made and tested on ePSXe for Linux (stated above, before the index).
I guess that the files structure are the same on Linux and Windows but I cannot
be certain, since I can't and won't install Windows EVER AGAIN :P
EDIT: in fact the save states works in both versions. Just tested the Windows
version using wine. (and, surprise! running the Windows version via wine is way
better than playing the native Linux version. Go figure...)
As I said earlier it takes some effort to hack the states. First thing,
ePSXe save states are compressed using gzip, so before you edit anything at all
you must decompress it (used gunzip but I guess 7-Zip, WinRAR, should do the
trick on Windows). Then you load the file on your hexeditor, edit whatever you
want, then recompress the file. Remember to remove any file extension that gets
added to the recompressed file, if any. Now you can load the save state on the
emulator. A word of warning, it seems that ePSXe somehow keeps the save state
in memory, so to edit it you must close it before. Phew! I said it was tricky :)
EDIT: I recently used ePSXe 1.7 -- wine emulation :P -- and there's no need to
gzip the file again after you're done editing it... just load it (no need to
restart the emulator too!!)
So, to be clearer, that's how I (used) to do it myself:
$ mv SCUS_942.54.001 SCUS_942.54.001.gz
$ gunzip SCUS_942.54.001.gz #decompressing the file
$ bless SCUS_942.54.001 #loading on the hexeditor
$ gzip SCUS_942.54.001 #done editing, recompressing it
$ mv SCUS_942.54.001.gz SCUS_942.54.001 #removing file extension
$ cd ..
$ ./epsxe #play away
Since now there's no need to gzip again the file neither restart the emulator
it may be already running... SO here's the improved way:
$ wine ePSXe.exe & #yeah the windows version IS better :P
$ cd sstates/
$ mv SCUS_942.54.001 SCUS_942.54.001.gz #save state name of course
$ gunzip SCUS_942.54.001.gz #decompress file
$ bless SCUS_942.54.001 #load it on hexeditor
#reload it on ePSXe and play away
BACKUP YOUR FILES before you edit them to save yourself a lot of grief
in case something goes wrong! Saving in two or more slots and editing one does
the trick neatly.
1.1 Characters stats offsets
I'm still not sure if the character's offsets are dependent on their
position on the party. So, they're listed here in the order I've found them
on the save state BUT I'm not sure what happens when characters leave the
party, I've only recently started a game to test this. Future revisions will
shed light on this subject.
All values offsets are reversed i.e. most significant digit goes last.
For example, if you want to have 1000 HP on Justin (0x03E8), you should edit
his maximum HP offsets (0x10432-0x10433) like this: 0xE8, 0x03.
A side note, if you change any of the items equipped, the game doesn't
automatically correct your battle stats. You must swap the weapon off then on
again (or maybe level up the char? haven't tested that yet) and only then the
correct value will be on. You can equip any item in any slot (i.e a Sneakers on
your shield slot o_0) BUT if the item can't normally be equipped in the slot
you put it on (or at all) when you swap another item in, you won't be able to
re-equip it in the wrong slot unless you hack the value back in again.
1.1.1 Justin (or 1st Party Member?)
HP (Current/Maximum) 0x10430-0x10431 / 0x10432-0x10433
STR 0x10434-0x10435
VIT 0x10436-0x10437
WIT 0x10438-0x10439
AGI 0x1043A-0x1043B
SP (Current/Maximum) 0x1043C-0x1043D / 0x1043E-0x1043F
Weapon (Sword) skill level 0x10456
Weapon (Mace) skill level 0x10457
Weapon (Axe) skill level 0x10458
L1 MP (Current/Maximum) 0x10462/0x10463
L2 MP (Current/Maximum) 0x10464/0x10465
L3 MP (Current/Maximum) 0x10466/0x10467

Jewelry Equipped 0x1047C-0x1047D
Inventory slots 0x1047E-0x10495
1.2 Gold
All values offsets are reversed i.e. most significant digit goes last,
just like char stats. For example, say you want to be filthy rich and have
one million gold pieces (0xF4240), fill the offsets this way: 0F on 0x10320,
42 on 0x1031F, and 40 on 0x1031E.
Gold offsets: 0x1031E, 0x1031F, 0x10320
1.3 Lists
The value 0x0000 corresponds to a empty slot. Note that each item
consists of two offsets, so there are 65535 possible values. I made a broad
sweep through this range of values, only tested a few hundred of them. There
may be items that I didn't find because of this. If someone smarter than me
manages to automate this tedious task of checking all possible values, a
comprehensive list of *ALL* combinations may emerge. But, my guess is that most
values will be garbage anyway.
Garbage offset values may or may not work. This includes things like
unnamed items, "+35 move", "+5 water level", iconless things, Japanese strings,
and so on. Some even are equippable, for example you can equip "+5 water level"
as a weapon, I wonder what it does in combat... :)
