  1.0   Introduction

This guide details how to manipulate saved files in Sega 
Ages 2500 - Phantasy Star: Generation 2. Having beaten 
the original game way back when (and becoming a massive 
fan of the series as a result), I made the plunge and 
picked up the remake about 18 months back. By the time I 
got to the Yellow Dam, I was finding the process of 
grinding my characters repetitive and time consuming, and 
not having the same resources I had (i.e. free time) when 
I was 11 when I first played through the game, I was keen 
to find a way to cut through the game. The following 
guide, while a bit convoluted, describes the method I 
used to successfully hack my save files to varying 
states. For those who are curious, I have also uploaded
two save game files, one with see pre-hacked saves (prior
to Neifirst and up to the Yellow Dam), and hacked saves
(Neifirst, Dark Force and Mother Brain + a clear data game
with normal stats).

  2.0   Hacking Guide

<: Requirements :>

- Playstation 2 console that can launch homebrew software 
  (i.e. by using swap magic, etc)
- Memory card with Phantasy Star: Generation 2 save file 
  (either make your own or download an existing one)
- ULaunch software (for Playstation 2)
- Windows XP (Vista should work as well, but I can't 
  guarantee it)
- PCSX2 (v0.94 or higher; see guide for PC specs)
- MyMC (used for extracting save files from PCSX2 memory 
  card files)
- PS2 Savebuilder
- Cheat Engine (v5.4 or higher)
- USB drive

<: Preface :>

Firstly, you do this at your own risk – there is a very 
real chance you could lose or corrupt all the save data 
on your memory card by doing this, so if you break 
anything, it's your own fault – you have been warned! 
Make sure you make a few backups of your data in case you 
mangle something along the way. 

Secondly, this guide may be brief on some parts and will 
require you to be a bit computer savvy – outside the 
scope of this guide is getting your PS2 ready to utilise 
homebrew software (like uLaunch), setting up PCSX2, using 
MyMC and PS2 Savebuilder and the location of a good deal 
of the software described herein – remember, Google is 
your friend and will help fill in the gaps! I'll revise 
the text as time goes on, but you'll have to bear with me 
in the first few versions of this document.

Third, you don't need to understand the basic precepts of 
hex editing and save game editing to make use of this 
guide, but it'll certainly help. Do some Googling for 
hacking ROMs and save games/save states for more info – 
there are even some guides on GameFAQs, such as the 
listing for Seiken Densetsu 3. I'm still a beginner on 
this stuff, so I figure if I can get my head around it, 
anyone should be able to!

Finally, the guide is written so you hack your own save 
file – if you've downloaded a file and have imported it 
into your memory card file in PCSX2, you can skip the 
first few steps.

<: Tutorial :>

1: Load up uLaunch on your PS2 with a USB drive connected 
to your PS2 and your memory card in slot 1. If you're 
wary of stuffing up your save data, use an empty memory 
card or backup your save games, including your original 
unhacked Phantasy Star 2 save game (the latter is *very* 
important! Make 2 or 3 copies, just in case you ruin your 

2: Start the file browser and navigate to your memory 
card (if it's in slot 1, it'll be mc0:/) and navigate to 
your Phantasy Star 2 save file, which should be "BISLPM-
62553". Tag the file by pressing X, then press R1 and 
select "Copy". Head back to the root directory listing 
(press [Triangle] a few times) and select your USB drive 
(noted as mass:/), then dump the file in any folder you 
like (press R1 and select 'Paste'). Make sure uLaunch is 
no longer accessing your USB drive (I normally press 
[Select] on the controller to take you back to the main 
menu; if you're going to be a while, you might as well 
turn off your console), and take out the USB drive.

3: Now we have to transfer the save file across to the PC 
– take your USB drive and copy the BISLPM-62553 save file 
folder across to your PC. Make a second copy somewhere as 
a backup on your PC or USB drive, then plonk another copy 
somewhere so you can manipulate it (e.g. your Desktop or 
another temporary folder).

4: Open PS2 Save Builder so you have a new file, then 
drag and drop the three files from BISLPM-62553 into the 
window. Make sure that "BISLPM-62553" (without the 
quotation marks of course) is listed in the Root dialogue 
box; if you don't do this, the game won't load!

5: Now that all your files are in there, goto File >> 
Save As… and save it into any random file format (I 
normally use .xps, e.g. ps2original.xps) – take note of 
where you saved it, because you'll be needing it for the 
next step.

5: Open up MyMC and find the memory card folder in PCSX2 
(if you haven't already, start up PCSX2 without loading a 
game, go to the browser and format your memory cards to 
activate them), normally filed under 
"\Pcsx2_0.9.4\memcards" – grab "Mcd001.ps2" and open it. 
You should have the system info and any save files from 
PCSX2 in there.

6: Time to add the PS2 save file – select File >> Import, 
grab your original PS2 file, and you'll see it has now 
been added to your memory card. Close off MyMC once 
you're done.

7: Start up PCSX2, but make sure you load up "PCSX2t.exe" 
– it may work by loading up the standard "PCSX2.exe", but 
I *think* you get easier memory access by doing it by 
using "PCSX2t.exe". Next, load up Phantasy Star 2 – if 
you've done everything right so far, your save files 
should be in there. Load your game of choice, and get 
ready to start hacking.

8: Once your save game has loaded, tap [escape] to go 
back into the menu for PCSX2, open up Cheat Engine, then 
click the 'Select process' button (the little computer 
icon in the top left-hand corner), and find PCSX2 

9: Now it's time to start playing around – load an 
address into Cheat Menu by clicking the "Add address 
manually" button. For the sake of this guide, load in the 
address for changing your meseta - 09F38344. Once its 
been loaded in, you'll notice the address listed in the 
bottom part of the window has a couple of other settings, 
but the one you're after is "Value". If you've done 
everything correctly, the number in the "Value" field 
should be exactly the amount of meseta you have. To 
change this value, simply double click the "Value" box 
and put in your desired amount of meseta (e.g. 999999) 
and select ok.

10: Test to see if it works – go back to PCSX2, select 
Run >> Execute to jump back into your game. If you have 
any menus open in-game or if you're in a shop, exit out 
so you're back to just being able to walk around. Press 
[Triangle] to bring up your menu, and if you've done 
everything right, you're meseta will be 999999! To change 
other values, simply follow steps 8-10 to perform the 
hack. You can either adjust stats individually, or you 
can do everything in a single hit – it's entirely up to 
you. Be sure to read the notes in section 3.0, as 
levelling up will have an adverse affect on any boosts to 
your attributes.

11: Once you've finished hacking your characters, head to 
a Data Memory house in any city and save your game, then 
exit Data Memory and exit the game and close PCSX2.

12: Open MyMC again and navigate to your memory card (see 
step 5). Find the Phantasy Star 2 save file, then goto 
File >> Export and give the file a useful name (e.g. 
super-ps2.max) and save it any format (I used .max).

13: Create a folder on your USB drive with "BISLPM-62553" 
as the folder name – put it somewhere you can identify it 
as your new save file, such as "\New hacked ps2 

14: Open PS2 Savebuilder and load the new save file. 
Highlight the three files listed in the save file, then 
right-click and select "Extract", then save it into the
new "BISLPM-62553" folder. You have now created a fresh
Phantasy Star 2 save file in the native Memory Card format!

15: Insert your USB drive, open uLaunch, navigate to the 
new save file in your USB drive (i.e. mass:/)and tag the 
BISLPM-62553 folder, select copy, then navigate back to 
the main device listing, select your memory card (e.g. 

16: If you have an existing Phantasy Star 2 save file 
present, (i.e. BISLPM-62553), rename it (e.g. BISLPM-
62553.old) or (preferably, but only if you have a backup 
of the original!) delete it by tagging the file (i.e. 
press X), then press R1 and choose to rename the file or 
delete it. If you don't have an existing save file, 
ignore this step and move onto step 17.

17: Once you've taken care of any existing files, press 
R1 and select "mcPaste". The file will be copied across.

18: Once its finished copying, head back to the main menu 
by pressing [Select], turn off your PS2. You can either 
check your memory card to see if the file is there (it 
should be, with a recent modified date). If it's all 
there, load up Phantasy Star 2 and see how you go. If 
you've done everything correctly, you can continue 
playing the game with your newly hacked characters!

  3.0   Address values

The following notes point out the address locations for 
hacking your data in the game. Make sure you read the 
notes, as they explain some of the "rules" to hacking 
your characters successfully.

<: Meseta :>
Address: 09F38344
Max value should be set to 9999999 (7 digits) or 999999 
(6 digits). I've only pushed it to 6 digits, and it was 
happy to move into seven digits after some fighting and 
getting more money. I'm not sure if it can go beyond 
that, so watch out if you push to 7 digits and the game 
crashes/corrupts if you have a few battles and shoot past 
7 digits for your meseta.

<: Character stats :>

 -- Levels, experience and stats: the relationship 
    between them

Here's a little thing about Sega Ages PS:G2 – your 
attributes (strength, defence, etc) are directly linked 
to your levels. Your levels are linked to your 
experience. Mess one up, and everything falls apart. So, 
even if you've maxed out your attributes to a base of 999 
but you haven't maxed out your levels and exp 
appropriately, the moment you hit a new level, all of 
your attributes will reset. Bummer.

So there are two ways to mess around with your 
character's stats – either bump their level + experience 
to a certain point (for example – level 50) and leave the 
attributes, or push to level 99, 999999 experience and 
have fun with your attributes. I'll give instructions on 
maxing your characters out with the expectation of 
keeping your level at 99; if you're looking at a more 
moderate boost, you'll have to play around with your exp 
amount. You may be able to get by with only changing the 
level of your character, but I can't guarantee it since I 
haven't tried it. See the Q&A for some ideas on what to 
do if you're only after a moderate boost.

 -- Techniques

Techniques are also connected to your level. Granted, you 
could probably hack them in, but you might as well just 
hack your level instead. After hacking your level, go 
into a fight, win (d'uh), and the screen will inform you 
when it rounds up all the stats that your character has 
learnt a new technique. Go into your characters list of 
techniques under their stats, and lo and behold, you'll 
have all the techniques up to your desired level.

 -- Recommended maximum stats

Level: 99
Experience: 999999 (up to 8 digits/max)
HP/MP: 999/999
Attributes (strength, defence, etc): 999
Meseta: 999999 (up to 7 digits/max)

 -- To boost your character to max base stats:

1: Make your level 99
2: Make your exp 999999 (six digits)
3: Make all your attributes 999
4: Go into a battle, finish it, then you'll get all your 
   techniques maxed out

 -- Addresses/values for character stats
Names are given as original English name/Japanese name to 
make everyone happy. Translations of the stats are taken 
from Wolfgang's awesome and exhaustive guide to the game

<: Resurrect Nei after the battle with Neifirst :>
Address: 09F377AC
To resurrect Nei, get passed the fight with Neifirst, 
allow her to die, etc, then go back to your house in 
Paseo. Remove all party members from your group, then 
exit the house, ensuring you're the only member of the 
party. Following the usual hacking procedure, plug in the 
address in CheatMaker, change the number in the "Value" 
field of the address from 0 to 1, then jump back into the 
game. Go back into your house in Paseo, goto Party Member 
Change, and Nei will be selectable; add her to your 
party. Exit your house again and take her to the 
resurrection shop/whatever, and resurrect her. If you 
want, pump up her stats if you haven't already, then 
continue the game with her. I haven't tried finishing the 
game with her yet, so I don't know if this will result in 
the cool ending or if it will unintentionally break 
something. I also don't know where her special claw 
weapon is, as I'm pretty sure you get it as a result of 
resurrecting her properly. If anyone has a save game with 
Nei resurrected the proper way and can upload it to 
GameFAQs, I can grab the address for the item so you can 
hack two of them into your inventory to use in a later 
update to this FAQ. 

  4.0   Q&A

Q: Why didn't you just hack a saved game file or saved 
A: I actually did both before I went through this method 
– unfortunately, I'm still new to hex editing and wasn't 
able to work out where the checksum values are stored for 
each save slot, so the hacking the saved game file kept 
on resulting in corrupted files. I managed to hack the 
save state, but when you saved a game from the save state 
file, it corrupted the main memory card-based save file 
also. This method is therefore the best method I have 
come up with until I can work out where the checksum 
values are stored.

Q: Why don't you simply use PCSX2 to patch the game 
instead of Cheat Engine?
A: I used Cheat Engine as it was useful in doing 
comparisons between states – if anyone wants to do 
something similar in PCSX2 by using any of the techniques 
in this guide, go for it – if possible, link back to this 
FAQ with some credit, thanks.

Q: What are the values for the other characters?
A: That's on the To-do list (see 3.0) – I'll get off my 
lazy behind in due time to sort those out.

Q: Can you add items into your inventory?
A: Yup, but I haven't worked out a list. Guides for 
hacking the original Phantasy Star 2 on the 
Megadrive/Genesis have noted that the trend for the items 
that the further up the address scale you go once you 
find the item pool, the better the item; I wouldn't be 
surprised if the same theory works here. I'm keen to grab 
the value for the Visiphone since you can't use the same 
method for grabbing it that you use in the original game, 
but unless I have a save file with the item, it might be 
a while coming. I wouldn't mind duping some of the Nei 
items as well (such as the Nei Slasher).

Q: Will I get the special ending if I resurrect Nei?
A: Not sure, possibly not – the address simply re-adds 
her to the party, the game may check other values after 
you trounce Mother Brain to determine if you get the 
special ending. I'll give it a try when I get to the 
final boss and see what happens if somebody doesn't beat 
me to it.

Q: What are some good guides to this game?
A: Apart from Jack Power's guide on GameFAQs, Wolfgang 
Landgraf has an exhaustive guide to the game I have found 
invaluable. You can check it out at:


Q: How do I get past the Roron dump section?
A: I had an e-mail I wrote a while ago detailing it… but 
I can't find it :P Going by memory, make sure you have 
all the characters waiting at your home in Paseo (go back 
and forth into your house until new people stop coming 
in), then follow Wolfgang's guide and talk to all the 
people in Kueri and Zema, you'll eventually start 
triggering events. Once sorted everything out, you'll get 
the Maruera Berry to give to the specific Motavian Native 
in the dump – don't give it to the wrong one! I'm not 
sure if it will work, but I'll track down the address for 
the Maruera Berry in Cheat Maker and update the FAQ with 
the details so you can simply add it to your inventory 
(that being said, I don't have a save file with the 
Maruera Berry – if someone wants to post one on GameFAQs, 
I'll be happy to have a look at it and credit you for 
helping out); it might mess up the game depending on how 
tight the events are, so don't count on it!!

Q: How do I get the Maruera Gum?
A: Similar to the above, make sure you go home and get 
all the new characters, then follow Wolfgang's guide; 
you'll be sorted after that. Alternatively, I still have 
the Maruera Gum in my save file, so I'll post the address 
for it in a later update.

Q: I hear that you can create trainers using CheatEngine 
that can be run independently of the program – how about 
making one of those?
A: I only read about this after I started writing this 
FAQ – I'll look into doing that once this guide has 
reached 1.0 and see what I can come up with.

Q: I only want to make my characters level 50, not 99 – 
how much experience should I give them?
A: Not sure on that one – you could leave your 
characters' exp alone and simply hack your level and see 
if the system tries to reset anything after a battle and 
see what happens. If it carries on without a worry, 
you're in luck. Otherwise, you'll have to hack your 
level, jump into the game, find the characters' stats 
screen, see what number is under 'next' and make sure 
that you hack your characters' experience so that it's 
less than that number. To be honest, the inconsistency 
shouldn't break the game, but I'm not going to guarantee 
it won't munt it either. And no, I'm too lazy to rig up a 
table showing the relationship between levels and 
required exp for all eight characters :P

Q: Will you do something similar for PS:G1 released as 
part of the Sega Ages series on the PS2?
A: Probably – I just managed to find a second-hand copy, 
and I'll look at doing something similar once I've 
refined this one a little more if the difficulty is rock-

Q: How about one for the Phantasy Star Complete 
A: No way – there's already a stack of easy modes 
implemented therein to soften the blow. My rationale 
behind this guide was to make PS:G2 a bit easier for 
those of us who don't have the time to grind as hard as 
we had to back in the days when Phantasy Star 2 first 
came out!

Q: How do you steal the Visiphone in the remake since there
isn't a baggage room in the Central Tower in Paseo?
A: Here's what I did - I cranked Shir up to level 99 (should
be possible at around level 20-30 I assume, but I haven't tried
it myself), had only Shir and Rolf in my party, and visited
the Central Tower in Paseo. I would enter, visit the commander,
then visit the librarian, then exit. I repeated for approx 25-30
times, then Shir ran off. After that, I went back to Rolf's
house, collected Shir, and I had the Visiphone in my inventory.
I wasn't sure if visiting the librarian or the commander did
the trick or if you have to do both, but that's how I did it.

Q: How do you get to Naval?
A: You get to Naval via Skure - there are four exits to Dezo on
B2F, three of them take you to the three cities on Dezo, and the
fourth, which is located on the far-left series of platforms on
that floor, takes you to Naval.

Q: Are you going to add the addresses for the other items?
A: I tried giving it a go, but couldn't track down the addresses
for the items. I might try again in the future, I might not :P
The big thing was getting the Visiphone and working out the other
special items - I've covered the techniques for these earlier in
this guide, which you can use in combination with Wolfgang's
excellent site. For the a detailed guide to properly doing the Nei
Resurrection, see Jack Powers' guide on GameFAQs.

Q: Where can I obtain your save game files?
A: GameFAQs.

for their excellent guides and replying to my e-mails a 
while ago with attention and detail, the Madboards crew 
for putting up with my ongoing rants about the brilliance 
of this series, and most of all, to my other half for not 
minding the fact that I probably spend too much time 
tinkering on the PC doing stuff like this instead of 
spending time with her!

Oh, and a big shout out to the old-school Sega – bring 
back the love, and give Reiko Kodama a team to make a new 
Phantasy Star or Skies of Arcadia game, I think the 
gaming world (and your bank roll) are in need of it!
