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...It'll get better soon I promise :D
------------------------------------
This is a save state hacking guide for Breath of Fire IV, a classic PSX
RPG by Capcom. Why I bothered writing this stuff? Well... I've done it JUST to
BEAT mo&##$*@>@er Rider without having to grind to level 50+. That's reason
enough to you?! :D
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 I mean I had one... CD's so badly
scratched it won't ever work again that's for sure...
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
YEAHHH you can rename everyone if you wish to :)
As a note, multi-offset stats (HP, MP) are inverted i.e most significant digit
goes last. Just like the money offsets, check below.
1.1.1 Hidden Stats?!
There are some char stats are hidden from the main menu i.e. no way to
figure, in-game, their values. They follow basically the same hidden stats that
existed on BoF3 (yeah they were there too!!). All thanks to Zhi Cheng Liu for
this. Check his BoF3 Secrets Guide for further explanations along with some
nice tables and in-depth info on them.
The hidden (BoF3) stats are: Willpower, Resistances (Physical, Fire,
Ice, Electric, Earth, Wind, Holy, Mind, Status, Death), surprise rate, reprisal
rate, critical rate, dodge rate, and attack accuracy. Willpower is the chance
of auto-revival during battle when you are KOed the first time, the resistances
are how well a given char copes with an element attack on him/her, surprise
rate are your chances at first strike at battle, reprisal rate is counter
attack frequency, critical rate is how ofter you crit when you attack, dodge
rate is how often you dodge an incoming attack, and attack accuracy is, well,
self-explanatory :P Willpower and surprise/reprisal/critical/dodge/accuracy
rates range from 0x00 to 0x64 (i.e 0 to 100 decimal), the resistances range
from 0 (most vulnerable) to 7 (damage is negligible or absorved). Like other
stats, there are both natural values and equipped values for all of those.
All that said, I still haven't tested all this very well yet... there
are some values that are easy to guess (i.e. Ryu is strong to fire and weak to
ice and Fou-lu is just the reverse...) Also, the list may not be exactly the
same as BoF3... it will take some time to pinpoint exactly which offset is
which, coming in a future update :) The list below are the natural values of
all chars (values in hex):
Ryu 02 02 02 02 04 02 01 02 05 02 02 02 19 0A 06 06 32 64
Nina 03 02 02 02 02 03 02 02 05 02 02 02 00 00 00 14 32 64
Cray 02 02 02 02 02 02 02 03 05 02 02 02 00 0F 04 04 37 64
Scias 02 02 02 02 02 02 03 02 05 02 02 02 00 14 08 0F 46 64
Ursula 02 02 02 02 03 02 02 02 05 02 02 02 00 00 02 0A 37 50
Ershin 02 03 02 02 02 02 02 02 05 05 05 19 00 04 00 1E 5A 39
Fou-lu 02 02 02 02 01 02 04 02 05 07 07 07 19 14 0F 08 46 64
So my educated guess, with the very little testing I've done so far, is that
the order is: *dunno*, Physical?, *dunno*, *dunno*, Fire, Wind, Ice, Earth,
Holy,Mind,Status,Death, Suprise, Reprisal, Willpower, Dodge, *dunno*, *dunno*.
Lots of *dunno*... It will get fixed soon don't worry :)

1.2 Money
Money offsets are reversed i.e. most significant digit goes last...
Example: to have 50000 Zenny (0xC350) you must fill the offsets 0x50 - 0xC3
Money offsets: 0x11AF3A, 0x11AF3B, 0x11AF3C
1.3 Items
Items are composed of two offsets, the first defines which item and the
second, its quantity. For example, to add 15 Panaceas to your inventory on the
very first item slot, put 0x0E on offset 0x11AF52, then 0x0F on 0x11AF53. :)
Inventory offset start: 0x11AF52
