[PSX/PC] General editor - Hades Workshop (0.41c)

[Tirlititi]

Hi there !

I'm working on a Final Fantasy IX modding tool called Hades Workshop. It is aiming to allow to edit most of Final Fantasy IX's content. Quite a big project and I don't know if I will ever decide when it's finished 

//============== THE TOOL =================//

The features so far:
- Can mod Final Fantasy IX PSX files, in .bin format and in any language version,
- Can mod Final Fantasy IX Steam games,
- Read and edit datas about :
--- Spells the party can cast,
--- Supporting abilities the party can use,
--- Commands the party has,
--- Default stats of the party members,
--- Items' features,
--- Items sold in shops,
--- Statistics, attacks and AI of enemies,
--- Tetra Master cards,
--- Text, dialogs and charmap,
--- Game's script,
--- MIPS script and CIL script,
--- Model exporting/importing (exporting Battle Scenes only for PSX, more for Steam),
--- Backgrounds (view only in PSX, view/replace in Steam),
--- Steam resources exporter/importer,
--- Spell animation sequencing,
--- Includes a game Randomizer.
- Works under Windows only (you may recompile the source code I redistribute or use wine under linux).

It may be a good idea to have a look at the help (F2).

Since the version 0.41, Hades Workshop is partly compatible with Albeoris's Memoria Engine Modification tool for the Steam version of the game:
- It can produce .csv files suitable for Memoria's usage,
- It can produce independant asset files and, using the incorporated tool "Unity Assets Viewer", can import those assets into modded archives,
- However, it cannot use Memoria's modded DLL to read game's data: a backup containing a non-Memoria Assembly-CSharp.dll has to be used as input (the archives, "p0dataX.bin" and other "XXXX.assets" files, can be used to read game's data even if they are modded using Memoria, which makes the use of the Unity Assets Viewer tool non-necessary to do a mod compatible with Memoria).

Credits:
I made the program, obviously, but I got helped a lot by your wiki (http://wiki.qhimm.com/view/FF9) for cluster datas format of the PSX version and by http://finalfantasy.wikia.com/ occasionally.

Other than that, LandonRay and Zande made quite an useful work in data finding, Zidane_2 wrote most of the other tools about FFIX before me.

The launcher image on has been drawn by Maxa'. You can check his Deviant-Art page here.

Please tell me if you get any suggestion/bug report/feedback to share.

Thank you for your attention 

//=============== THE MODS =================//

Here are some of the mods that were made using this tool by various people. Go see their description for more detailed informations.
Difficulty Tweak: Made by Iamthehorker, this mod increases the MP cost of the abilities and make the battles tougher. The gameplay itself is preserved, so it really is an increase of difficulty for an augmented playthrough. If you think that the boss battles end too quickly or if you never saw the use of the ethers/elixirs, this mod is a way to go. It also allows Steiner to equip the Save of the Queen in the end-game.
Save The Queen: A mod made by ThisGuyAreSick2. It allows Steiner to use the allmighty Save The Queen. It also changes the way you synthesize it (it's made in the Black Mage Village in disc 4).
FF9.2.2: A mod made by Vir to improve the Perfect Stats challenge balancing. It removes the forced exp battle so a true lvl 1 game can be made. It also fixes the Thunder Slash glitch. Vir also made a Fixed Stats Mod which removes the primary stat variations from games to games and have a normalized stat progression.
HD Background: This mod made by Fraggoso for the Steam version of the game improves the backgrounds on the field and make it fit more with the upscale of the characters. There is also a Highres Texture mod, applying the same process to the other textures of the game.
Alternate Fantasy: My own mod. It modifies a bit of everything in the game but mostly change the abilities and the gameplay in battles.

Also, you can find here the different tiny mods I made over the years.

//============== HELP AND TIPS =================//

This topic is now more than 30 pages long. Different people asked for help at different points and I always tried to give a complete answer. You can thus find details in this topic about subtilities of the game, or how a feature of HW works, or how to do some precise thing. Since I don't want everyone to read the whole topic thoroughly, here are links to answers to these kind of questions.

Simplified Game Scripts

Here are some scripts of systems or mini-games that are of some interest if you wish to know how the game works in-depth.

Hidden dialogs

Here are some few interesting secret dialogs, never used in the game.
I've also made a patch to enable some of them in-game :
Hidden Dialogs (PSX)
Hidden Dialogs (PC)
And a video showing the patch's content.

Don't hesitate to tell me if you find more unused dialogs : I'll add them to the list ^^

Morrid “What will you do if Alexandria starts a war?”
Steiner “When will the cargo ship arrive!?”

link not working :/

[Tirlititi]

Fixed, I added quotes around the link but it wasn't needed... 

Thanks for warning !

[xenokain]

Thanks  by the way im sure you can add the .dll into the program when building it. Some people choose to leave them out because it makes the program bigger i believe. I've heard of "external dependencies" when building source code so im sure you can choose to have it built into the program or make it so you can get the .dll seperately. Not sure how Codelite + wxFormBuilder works though.

[JBedford128]

Well, this saves me time trying to make my own program with my very limited knowledge on reading from files.

You may want to look at this. I noticed you are missing some of the stats.

Also I haven't figured out the statuses yet. I know some relate to class (Aerial enemies are immune to Float, for example). And I haven't found where the Card is stored. But I imagine the Card drop might be based on the encounter/formation and not just individual enemies. I don't know where the formation data is so I haven't looked around. Also I see where the attack data is probably stored (after the enemy stat data) so this guide may prove useful if you plan on figuring that out.

I assume what the program calls CP is actually AP?

I also think it would be useful if you still gave the number of the formation. So on Disc 1, the Beatrix battle is file0, so having it say "0: Beatrix" would be a help.

But anyway, I love you for doing this. This is extremely useful.

Depends on the library. If the source is open you can copy what you need into your project. Otherwise, it's safest to distribute the library with it as it may have external dependencies as well. Honestly, size doesn't matter so much anymore. Back before Harddrives were less than 10 GB it would be important to cram as much into as little as you could. Now it's hard to find a machine with less than 80 GB which is more than enough for most people (although my 2TB machine is more than half full ).

[Tirlititi]

Many thanks for the links, JBedford128. I didn't see this topic before ! Very useful.
About enemies' attacks, I know some things about it but the datas are splitted everywhere and particulary in the script file for the AI (that includes which monster uses which attacks...). I still lack knowledge on scripts, though I got some opcode values.
Yeah, maybe the card drop is in the enemy formation, there are a couple of bytes I don't know in it.
And yes, CP -> AP. CP is the french thing and I messed up ^^'.

I also think it would be useful if you still gave the number of the formation. So on Disc 1, the Beatrix battle is file0, so having it say "0: Beatrix" would be a help.

Okay, I'll add that.

I'm quiet sure there is a simple way to remove the dll dependancies (it should be an option passed to the compiler) ; my attempts to do it just didn't work 

Next version will be focused on being able to overwrite datas. It'll be limited anyway but I'll try to make it as full as possible.

[NFITC1]

I'm quiet sure there is a simple way to remove the dll dependancies (it should be an option passed to the compiler) ; my attempts to do it just didn't work 

I don't think dll embedding is possible. I do enough assembly and disassembly to know that there's not a simple flag to tell a compiler to rip the code out of a library and mesh it with your code. There are lots of reasons this would not work. Unless you can get the source code of these libraries in your target language then I wouldn't think about integrating it into a single executable. I could give lectures about why trying to do such a thing is bad practice, but I'll spare you if you just trust me when I say you shouldn't.

[xenokain]

I think its better you keep it the way you have it with the .dll files just added to the rar/zip. you can always make the dll part a last priority (you can come back to) once you feel the program has developed enough.

[Tirlititi]

Updated. I've update the link in the first post so you don't have to search the last version through the topic.

The program may now overwrite datas directly in the binary file. Be careful because you can't unedit what you've done. I'm planning to add a system that saves a backup of the original datas in the .hwf file (when you open the file for the first time) but that's not done yet.
I also fixed that "fatal error" message when you exit the program.

About what you can edit, what you can't edit and what is limited (long boring post incoming ) :
- texts are limited both in size and in printable characters. You may only use characters from the US/EU char table (link) and size is limited to what the size initially allocated for all the datas of the same type. For instance, in the US version, there is a size of 1608 characters for ALL the spells names (including the terminating character, so it actually does 1416). In general, there is only up to 3 extra characters so you will most likely have to remove the names from other spells to get some space.
- You can't edit the enemy names yet (there is a way to have more space for them but that will be for another version).
- Commands spell lists are also limited. You may link 2 commands to increase the limit (they would share the same spells). White Magic and White Magic+ are linked by default, as well as Black Magic and Black Magic+ but you can link Dagger's eidolons (trance and normal) and the 2 Beatrix Seikens (dunno why there is 2 of them) so you win 12 spells to put anywhere for free.
- Editing commands don't change the spell list in the menu (only in battle). It doesn't add AP requirement to the character either, so he can use it without having to learn it.
- I added the "Model ID" field to the enemies, but that's more for testing and curiousness than for real use. I'm pretty sure it won't be simple to change the model. I haven't test it yet though.
- You can't change the enemy groups, apart from its frequency and the AP it gives. It would be safe to remove an enemy from a group but any other change would have bugging results.
- You can add up to 32 items to a shop, period.

I removed the "Targetable" flag. I thought it were used by things like the battle with Steiner and the Bomb behind him but that's not even the case. Since it's more something that deals with the battle's script, I'll leave it out for now.
I also added names to the shops. It may be inacurrate for the weapons and armors shops and it is imprecise for the item shops. If someone can confirm the last one is the Zorn and Thorn's shop right before Oeilvert, it would be nice of him.

I'll stop searching for removing the dll dependancies, then. That's not a priority either, as you said, xenokain ^^

Oh, and I added the numbers in the enemy list. I'll make it optional in the following versions, though.

[xLostWingx]

Love to see work being done with IX  Keep up the good work man.

[shikulja]

it is very cool). add image extractor and simple chars font editor. like chenge ierogliphs on other chars.

[xenokain]

Thanks for the updates  This is extremely useful.

[JBedford128]

I've noticed something strange with some bosses. They are displayed as having 10000 HP more than they actually have in the game. This explains why I couldn't find Ozma in the data when searching for his HP, and it also explains why Ozma has 55545, 10000 less than the upper limit.

There obviously is a flag that does this. Friendly Yan proves that 65535 HP is possible. So a flag removes 10000 HP from the given amount, which I can't think of any good reason for.

Edit: Well I think I might have found it. Before the HP value there is a string of 0s (in hex). But I noticed that both Beatrix and Prison Cage had an 80 (so 80 00 00 00 before the HP value). So I changed the 08 to 00 for Prison Cage, and used Death. And Death killed it. I didn't see its HP count though. So that might have just been some statuses that I changed. (additional note: Using Death on Prison Cage causes a game hang).

Edit2: Doesn't effect HP, but does effect some status immunities.

[Tirlititi]

Nonono, that's not that, that's AI-relevant.

When an enemy dies, he just dies, but some bosses (like Ozma, or even the very first Masked Man) actually have a more complex dying animation, which is in fact a spell (Maliris's ending movement is the only one that actually does something). So they have a scripted event : "When they have less than 10000hp, the ATB pauses, they cast a spell and then they die". There is a part of the hexa code about what I think is the event setup for Masked Man's battle :

Code: [Select]

05 D6 1E 0E 7F 02 EE 00 05 79 01 29 24 7D 10
27 1E 2A 7F 02 08 00 05 D6 1F 7D 01 00 2C 7F10 27 = 10000.
05 is the variable assignement opcode, so it's only about setup (38 is the opcode for an enemy to cast). I don't know a lot about how variables are coded but you can assume the opcode 05 is 7F-terminated. I don't know for sure what 02 is but it seems to be a sort of a JUMP opcode (01 is also JUMP, though...).

Ok, I just saw your 2nd edit. That's a good thing to know nonetheless, thank you

EDIT : Ha, sorry, that's not Masked man's battle, that's beatrix's battle. I just went confused with "1st battle in the game" and "1st battle in the battle list" 

[JBedford128]

Oh, that makes a lot more sense. ^_^

Death is tied to this, as both worked on Parasite Cage when I set it to 00. It also allowed Scan to work (it just seems to Miss otherwise), which allowed me to see the true HP. Everything else was Guarded (but I didn't test Venom (no player ability natively has it) or Vanish (which natively targets only allies)).

I don't understand Eat's relationship to it. I could Eat Parasite Cage (well, i didn't (i don't think i could given its HP), but it said "I can no eat until weaker"), but for Garnet it just plain said "I no can eat".

Edit: Oh wait, Garnet gets immunity from Eat because she is of the Humanoid class. Remove the class and she can be Eaten.

So I did some more digging.

Part of the enemy file:
----------------
00 00 00 00 [first-status-set. Status immunity]
00 00 00 00 [second-status-set. Status evasion, and sometimes auto-status]
00 00 00 00 [third-status-set. Status at beginning of battle/sort-of auto-status]
00 00 [HP]
00 00 [MP]
--------------------

Now, with regards to the status immunities:
Byte1 (01=Break, 02=Venom, 04=Virus. 08=Silence, 10=Blind. 20=Annoy, 40=Zombie, 80=??)
Byte2 (01=Death (but not Eat), 02[messes up targetting?], 04=Confuse, 08=Berserk, 10=Stop, 20=Auto-Life, 40=??, 80=Defend)
Byte3 (01=Poison, 02=Sleep, 04=Regen, 08=Haste, 10=Slow, 20=Float, 40=Shell, 80=Protect)
Byte4 (01=Heat, 02=Freeze, 04=Vanish, 08=Doom, 10=Mini,20=Reflect, 40=???, 80=Gradual Petrify)

It's the same statuses with all three sets of status thingies. 80000000 seems to do nothing, but the third-status-set uses 80000000 as a Death immunity. 00020000 is odd as an immunity. I'm not sure I could actually hit the enemy with it on.

So the first-status-set is Guard immunities.

The second-status-set work the same as immunities, but instead of saying "Guard" it says "Miss". Its other benefit is auto-statuses. The ones I've noted are Auto-Float, Auto-Haste, Auto-Reflect, Auto-Slow, Auto-Berserk, Auto-Poison, and Auto-Regen. I didn't go through each one individually, since I got the gist, so there may be more. However, I think Auto-Poison may be purely cosmetic. Unless I've forgotten how Poison worked, I sat waiting for the enemy to take damage but never did. I also suspect Auto-Slow may be cosmetic. I do know that Auto-Reflect works though.

There is also something interesting about Auto-Haste and Auto-Slow. When both are on, both the Haste and Slow indicators will appear next to the enemy. If one is on, and the one that is not on is inflicted on the enemy, both indicators appear then also. This could just be evidence that both are cosmetic and do not function as Auto-Statuses. But I don't know for sure.

The third-status-set inflicts the status at the start of the battle, however the effectiveness of this changes:
-If Stop is a selected status, then it can be removed. Unlike the second-status-set, there's no forced Miss.
-If a status is a temporary status (is removed after a duration) then the status does not stick. A graphic will be seen on start-up but that's it.
-For the countdown statuses, the countdowns are removed. If Doom is a selected status, the enemy will get Death instantly.
-00400000 seems to be Trance. The Masked Man was glowing, but it didn't do anything.
-00010000 and 00000040 have the enemy disappear and commands are never completed.
I also looked at other unknowns in an attempt to find out what they were. The two-bytes after the Animation IDs: Only of the bits in these bytes seems to do anything. "01" makes Prison Cave (the enemy I was testing on at the time) invisible.
-80000000 is the oddest. As discussed before, this is what bosses have. It Guards Instant Death, it makes Scan Miss, it makes Eat Miss (No can  eat), and a new revelation is that it makes Demi Miss too.

Also, after the Steal data, there are two unknown bytes, and then another set of two unknown bytes. For that second set of two unknown bytes, I set it to FF and it meant that when my characters attacked, they actually passed through the Prison Cage and attacked behind it. So these bytes may decide which part of a model the characters should attack.

Additionally, further down, the seventh and eighth bytes after the bytes deciding Blue Magic: These dictate where the cursor appears in relation to the enemy. I switched it to FF and it made the cursor jump all over the screen, but I also set it to a more stable figure that moved the cursor a couple feet upward from its original position. Additionally, my characters attacks towards the cursor. So this is like the bytes I mentioned before, except the offset effects the cursor too, which is not the case for the other ones.

Sorry if any of that wasn't clear, I'm not good with explaining things or words.

[Tirlititi]

It's clear enough, thanks.
I know a bit more than what the programs currently displays. I'll try to write it down.
The Enemy Chunk data has an ID of 10 and begins like every other chunk (see the wiki for that).
Then there is the "groups" datas :

Code: [Select]

1 byte Unknown
1 byte NbGroups
1 byte NbEnemyTypes
1 byte NbAttacks
2 bytes Battle Flags
2 bytes Unknown
Then comes [Nb Groups] times this :

Code: [Select]

1 byte Group Frequency
1 byte Nb Enemies
2 bytes Engaging camera ID
2 bytes AP
2 bytes Unknown
[
1 byte Enemy ID
1 byte Targetable Flag
2 bytes Unknown
2 bytes Position X
2 bytes Position Z
2 bytes Position Y
2 bytes Facing Angle
] (x4)
Then come the enemy's stats (the part you investigated). There are [NbEnemyTypes] of them (thx to you : I didn't know the purpose of the first 12 datas) :

Code: [Select]

4 bytes Status immunity
4 bytes Status evasion/auto-status
4 bytes Status initial cast
2 bytes HP
2 bytes MP
2 bytes Gils
2 bytes Exp
4 bytes Drop Item
4 bytes Steal Item
1 byte Unknown
1 byte Collision size (it tells how large some effects must be, such as scan)
2 bytes Aiming position, as you said (though I don't know more how it should be interpreted)
2 bytes Model ID (thx Zande for this and the followings)
2 bytes Animation ID 1
2 bytes Animation ID 2
2 bytes Animation ID 3
2 bytes Animation ID 4
2 bytes Animation ID 5
2 bytes Animation ID 6
4 bytes Unknown
2 bytes Attack Power
1 byte Speed
1 byte Strength
1 byte Magic
1 byte Spirit
4 bytes Unknown
1 byte Elemental guard
1 byte Elemental absorb
1 byte Elemental half
1 byte Elemental weak
1 byte Level
1 byte Class
1 byte Unknown
1 byte Physical defence
1 byte Physical evade
1 byte Magic defence
1 byte Magic evade
1 byte Blue magic
2 bytes Unknown
2 bytes Cursor position (not the one you mentioned but pretty much the same thing if I remember well)
2 bytes AKAO death ID (sound when he dies)
2 bytes Cursor position (the one you mentioned)
16 bytes Unknown
2 bytes Shadow Gap Y (didn't investigate it...)
7 bytes Unknown
1 byte Drop card
10 bytes Unknown
Finally come the attack stats. [NbAttacks] times this :

Code: [Select]

1 byte Unknown
2 bytes Model ID (though it seems unused ; the real model ID is in the 0x11 chunk file with the attack animations)
1 byte Unknown (often 1F or 5F)
1 byte Effect
1 byte Power
1 byte Element
1 byte Accuracy
1 byte Flags ("use reflect", "is magic" and I don't know the others, unfortunatly :/)
1 byte Status
1 byte MP cost
5 bytes UnknownAnd finally, 4 bytes end the whole thing, but I don't know what it might be.

About opcodes, since that's the most interesting thing I would want to hack next. Here is what I know :
The arguments of most opcodes can be either raw values or variable codes. A variable code is a list of variable operations terminated by 7F. I won't list operations here but there is a sample :

Code: [Select]

D40D 7D0200 20 D809 7D0000 18 27 7Fis translated into :

Code: [Select]

( Var_D40D == 2 ) && ( Var_D809 < 0 )20 is the == operation, 18 is the < operation and 27 is the && operation and 7D announce a short numerical value. So it is read like that :

Code: [Select]

D40D 7D0200 20 -> ( Var_D40D == 2 )
D809 7D0000 18 -> ( Var_D809 < 0 )
27 -> ( Var_D40D == 2 ) && ( Var_D809 < 0 )The result is put on the stack (for a following conditional jump, for instance).

The list of opcodes and their effect (for those I know of) can be seen in the file "Hades_Strings.h" of the source code. I don't list them cause there are a lot of them...

I'll update this post if you or me find more informations. Now I just discovered that the US version and the french version have a huge difference : in the french version, some important datas are compressed (with a compression method called RNC) in a sub-file, making them impossible for me to edit. But that's not the case in the US version... So I guess I'll end up making this program only open the US version...

The third set of status bytes do not have anything to do with immunity, they are just initial cast, and the status can be removed by standard means (like Remedy).

The fifth byte (first unknown byte, after number of attacks) of the data:
- 01 = When the battle ends in a non-standard way, do not continue battle.(used for bosses and friendly enemies--allows to continue fighting boss after death sequence if turned off)
- 02 = Always back attack
- 04 = [Unknown]
- 08 = [Unknown]
- 10 = no victory pose/no fanfare.
- 20 = cannot escape
- 40 = enemies are out of reach? (Masked Man could still hit me for full damage, i could not hit him)
- 80 = Cannot use magic (greyed out in menu, party members at least)
Sixth byte:
- 01 = Attacks take off a lot: I assume this is the Ipsen effect- weak weapons do more damage
- 02 = [Unknown]
- 04 = [Unknown]
- 08 = prevents the battle results screen.
- 10 = [Unknown]
- 20 = [Unknown]
- 40 = [Unknown]
- 80 = [Unknown]

Since my tests were against Masked Man I could have missed things, like if the unknowns were to effect EXP or Drop, or if the victory poses of some of the characters played or not (although it wouldn't make sense to decide that in the battle data- i thought the same about Magic block and the reverse weapons though).

For the first unknown (byte5) in Attack stats, you state it can only be 1F, but I have seen 5F frequently.

And I am using the PAL UK version and it seems to match up to the US version quite well. I've seen some differences, but most are translation.

[Tirlititi]

Ah, that's a good thing to know. I thought that RNC thing would be used by every european versions.
The header begins with "RNC\1" so if you search the hexadecimal sequence "52 4E 43 01" and find no results, it's sure that's not used. But I trust your test, it may just be a cleaner way to know it.
But for now, I don't seek datas written in this part of the file. That'll become a problem when I'll look for items, characters' stats and supporting abilities.

Thanks for testing the flags
I can't do as much testing as I would like to and I'm really grateful you take care of some. I'll release a new version soon, but I would like to make that backup system before.

By the way, the 3rd status set is used for death/eat/scan immunity, no? Even if it's only 1 bit. Also, what is break? You meant petrify?

[JBedford128]

Oh yeah, I forgot about that one bit. :p

And by Break I do mean Petrify. Break is the name of the spell. I did the same with Annoy: the status is actually "Trouble" but at the time my main source for status name was ability name.

Also I think I've very likely found the value that stores the card. Dendrobium and Fang both store "01" (both holding the Fang card, the second card) in the byte, and Goblin stores "00" (Goblin card, the first), Beatrix stores "FF" (no card), and Ironite stores 08 and Basilisk stores 05, which match up.

Code: [Select]

16 bytes  Unknown
2 bytes   Shadow Gap Y (didn't investigate it...)
7 bytes   Unknown
1 byte    Card drop (00 to 63, FF is none)
9 bytes   Unknown

I'll confirm this in an edit later (EDIT: Confirmed. I had a Fang drop an Airship card).

Above you may notice that I dropped a byte from what you originally wrote. The total I wrote would be 35 bytes in this section, but you have 36.

So take the Goblin/Fang one for example: After Goblin, there are 36 bytes in this section, then Fang's enemy-block starts. For Fang, there are 35 bytes in this section before the Attacks/Abilities block starts.

So there is an additional byte here between two enemies in the same scene? Or am I missing something?

[Tirlititi]

I checked again and I think you miscalculated.
That does 116 (0x74) bytes for all the stats.

[JBedford128]

Here's what I'm seeing:

...............................................
The only explanation is the attack data is wrong. It has one less byte near the start, and one more at the end. Because it says there should be four bytes before the "usually 1F byte", so I assume there should only be three.

If that were the case, it would also explain why I'm seeing five bytes that end the whole thing instead of four.

[Caledor]

Finally someone showing some love for FF9! Can't wait to see this tool completed!
By the way will it eventually be able to edit things other than magic names like weapon names and so on? And it is possible to avoid the char limit restriction for those sections?

[Tirlititi]

@ JBedford128 : Oh, yeah, the attack is wrong, I saw that when I implemented it but forgot to correct here (there is 1 byte less at start and I forgot the accuracy). Sorry.

@ Caledor : Yeah, weapons will be editable, but that's part of the datas that are compressed in some versions (if it only concerns the french version, that's not a big deal, though...).
I can't remove the char limit restriction for now. I can't even tell whether it is easy or would require deep restructuration of the file.
The only thing I can do for now is merging the names when they are the same. I guess I'll eventually do that.

[Tirlititi]

Update.
I added quiet a lot of stuff for enemies, some spell effects, fixed few bugs...
Also made the .ppf exporter. It does the same thing that a PPF creator, but much faster. The comparison is done between the changes you made and the file on the hard disk (so don't save before exporting the .ppf).

The enemies' spells animations are just there for information, they are quiet inaccurate or missing.

Now I'll take a break for a week.
