Version History
------------------------------------
2010 April 9: v. 0.9
-First Version, still a lot to do. Probaly a lot of wrong offsets and
values too... and typos... but hey I'm releasing it before prime time bear
with me okay? :D
2010 April 14: v. 0.91
-Added the money offsets. NOW you can be filthy rich, at least inside
the game :D
2010 April 16: v. 0.95
-Improved way to handle the save state files!!
-Figured out the Elements/Tech offsets & completed their lists. Most
work probably been done... but still missing the remaining char's offsets &
their grids with equipped Elements, and some minor stuff
------------------------------------
This is a save state hacking guide for Chrono Cross, a classic PSX
RPG by Square. Why I bothered writing this stuff? Well... this game is GOOD
I can tell you, and you probably know it if you are reading this! I've beaten
it beginning to end a handful of times but oh well... there's a lot of stuff
that requires far too many time to accomplish (i.e. get all summon elements is
one of them)... the game isn't hard but it ain't a pushover too and sometimes
you just want to breeze through it... I could go on but I guess you got my idea
right? :) 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.
And, before anyone bug me with annoying accusations, I played on a emulator
yes, but I DO OWN a copy of this game!
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, etc 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 Chars stats offsets
BEFORE you get frustrated, let me say that the status won't change
immediately after you change them. If you played before you remember that
after you grab a star your stats raise a bit an then a little more with battles
after it. It's the same thing here, you raise a stat then you must fight some
random battles, then it'll reach the value you hacked in.
TODO not all chars done!! read below.
You probably know that there's a ton of chars in the game. I plan to beat
the game to test it, but for now if you don't wanna wait it out you can (at
*your* own risk of course!) try to raise the other char's stats. Each char
seems to be described by 204 bytes, that always start as:
0x40 0x00 0x40 0x00 0x40 0x00
SO, I guess that all stats positions are the same for every char -- i.e
Max HP is 124 bytes off the char start offset, and so on. Have fun!! :D
ALSO you can send me your results if you don't mind... getting all the
possible characters requires at least some four playthroughs you know...
that's A LOT of work!! So help me out, ya? Pretty please? :D
1st char (Serge/Lynx)
Max HP 0x6EE3E
Current HP 0x6EE3A
STR. 0x6EE42
ACC. 0x6EE44
RES. 0x6EE46
MAG. 0x6EE48
AGI. 0x6EE4A
M.RES 0x6EE4C
Stamina Recovery (seems to be fixed by char, have to investigate further)
1.2 Money
Money offsets are reversed i.e. the most significant digit is the
last one. As a little example, say you want 150000G (wow that's a lot right!)
150000(decimal) = 0x249F0. You should fill the offsets like this: F0-49-02.
Money offsets: 0x71B62 - 0x71B63 - 0x71B64
1.3 Items
There's only one inventory, shared by **all** equippable items and
materials. It works like this: there's an offset where you define which item
you want, and another where you define its quantity. Quite simple huh? But mind
that in the definition offsets you must space the items with a 0x00 between
them, like this:
--first offset: 0x7149A, say you want a @Rainbow Shell: 0x06
0x7149A -- 0x06
--let's say you want forty of them (plenty huh)
0x7179A -- 0x28
--now you want five Sunglasses 'cause they rock so much: 0xF7
0x7149B -- leave empty, 0x00
0x7149C -- 0xF7
--five of them right?
0x7179B -- 0x05
Inventory -- items, weapons, etc
Item definition offsets (start): 0x7149A
Item quantities offsets (start): 0x7179A
So simple right? Now go nuts with the @Shiny materials that are SO damned
boring to create... :)
1.4 Elements/Techs
Elements are just like inventory items: there are two relevant offsets,
one defines the element and the other its quantity. Element definitions are
spaced with one empty offset 0x00 just like the inventory ones. As a example,
say you want 10 Volcanoes and 12 Black Holes:
--first offset: 0x7191A, Volcano is 0x0C
0x7191A -- 0x0C
-- ten of them...
0x71A9A -- 0x0A
-- now the Black Holes:
0x7191B -- leave empty, 0x00
0x7191C -- 0x24
--...12 Black Holes
0x71A9B -- 0x0C
Techs show as regular elements too, but you won't be able to use most
of them, at least until I find out the equipped Elements offsets of course --
IF it is possible to use a Tech that wasn't designed for a given char that is.
But it will be very fun to find out!! :)
EDIT: it is possible to equip Serge's skills on Lynx!!!! The game doesn't lock
but the animation sprites look quite odd -- see it for yourself! ALSO as they
are White-innate they do great damage (as Lynx)... Using the MasterMune with
FlyingArrow shows Masa&Mune as your 'shadow'... if the sprites didn't look so
messed up you bet I would use it all the time :D
Elements -- all of them (attack, healing, consumables, traps, techs...)
Element definition offsets (start): 0x7191A
Element quantities offsets (start): 0x71A9A
