RE:REV ARC List

Noob question: how do I open/edit .arc files?

edit: I found the editor but it seems like editing arc files is too complicated, at least for me 

I see, thank you so much, I'll give it another try. I was wondering: is editing these weapons arc files the way you changed weapons properties for your ghost ship chaos mod?

Thanks a lot for your patience! I managed to extract the files and damn, those .lvt files are not easy to understand. I am going to work on them and see what I can get! I have a question:in your GSC mod you managed to mod a lot of things, including the properties of tagged weapons (you removed the negative effects from the unique tag) and weapon's damage (you boosted level 50 weapons damage, right?). Could you please tell me which files contain those informations?

edit: is the "playerTalent.lvt" file the one containing informations on characters abilities? I would love to balance some characters!

Oh I see, so the pc version is in little endian, that makes a lot of sense. I was endeed wondering why I was unable to find the codes of parts and tags. I found all these codes on a 360 forum (http://www.360haven.com/forums/showthread.php/26029-Resident-Evil-Revelations-Hex-Values-for-all-weapons-amp-all-parts) and now, writing bytes in reverse order I managed to find them in the .lvt files.
I am looking at the WeaponTagParam.lvt file and I think I found a pattern: 01 followed by tag code (3 bytes) followed by 80 02 followed by 33 bytes that I guess contain the info on the tag. For example, on the first line 01 01 00 09 80 02 (09 00 01 is the console code for long range) and then 33 bytes later we have 01 02 00 09 80 02, that is 01 and the code of easy grip followed by 80 02.
At line 00000280 I can see the code of the unique tag and the corresponding numbers: for example, the +35% damage (0x420c0000), written always as little endian.
I am going to tinker with these files for a while, hopefully I can get something good!

edit: I am having issues with repacking, nothing seems to work, even when I repack an unedited coop_table file. I am using the command arctool.exe -c -pc -rev coop_table. Am I doing something wrong?

Worked perfectly, thank you I can't wait to make a decent Rachel and most of all a decent Rachel Ooze!

I managed to fully break down the WeaponTagParam.lvt file and it is easy to change tag properties and values, I am going to make a post about that as soon as possible. But man, you are amazing, you nailed it, that's exactly Rachel's skills description. You are a genius! According to the japanese guide, Rachel parameters are:

damage taken + 12%
dodge time -25%
knife damage regular
knife speed +30%
Magnum RS (reload speed) +50%
Magnum FR (fire speed) +25%
Handgun RS -10%
Handgun FR -10%
Machinegun RS regular
Machinegun FR regular
Shotgun RS +30%
Shotgun FR +10%
Rifle RS -10%
Rifle FR -10%

The numbers coded after Rachel id (A0 10) are

1.12 (80B) damage taken
0.90 (810) pistol (FR than RS)
0.90 (815)
1.1 (81A) shotgun
1.3 (81F)
1.0 (824) smg
1.0 (829)
0.9 (82E) rifle
0.9 (833)
1.25 (838) magnum
1.5 (83D) 
1 (842) granades AoE radius
1 (847) Taijutsu damage
1 (84C) knife damage
1.3 (851) knife speed
0 (856) no idea 
0.75 (85B) dodge time
1 (860) regeneration

I think these are the correct values, I did a similar breakdown for Rachel Ooze and they match perfectly. Still no idea of what that 0 on 0x856 offset is, it could be related to Sailor Chris ability to become invincible after using an herb but it's just a guess.

Edit: after testing, I can confirm that's the structure and it is the same for each other character. I don't know Chris Sailor's code so I can't say what's the third to last entry.

Thank you, I managed to test Chris and yep, that entry is exactly for the invincibility.
So, to sum up, the playerTalent file contains all of the info about raid characters. The structure is the following:

01 V0 01 80 03 V1 03 V2 03 V3 03 V4 03 V5 03 V6 03 V7 03 V8 03 V9 03 V10 V11 03 V12 03 V13 03 V14 03 V15

V0 <char code > this is 2 byte long. All of the following are 4 byte long.

V1 damage taken
V2 pistol FR (fire rate)
V3 pistol RS (reload speed)
V4 shotgun FR
V5 shotgun RS
V6 smg FR
V7 smg RS
V8 rifle FR
V9 rifle RS
V10 magnum FR
V11 magnum RS
V12 granades effect radius
V13 Taijutsu damage
V14 knife damage
V15 knife attack speed
V16 invincible for 3 seconds after using an herb (value must be 1)
V17 dodge time
V18 regeneration

All bonuses are multiplicative. So for example, if I want to double my reload speed with an handgun, V3 must be 2.

Char codes 

10 10 - Jill (default)

10 11 - Jill (bsaa)

10 13 - Jill (pirate)

20 10 - Parker (default)

20 11 - Parker 2

20 12 - Parker FBC

00 10 - Chris (default)

00 11 - Chris (winter)

00 13 - Chris (sailor)

30 10 - Jessica (default)

30 11 - Jessica (winter)

30 12 - Jessica FBC

40 10 - Keith BSAA HQ

40 11 - Keith (winter)

40 12 - Keith Ninja

50 10 - Quint BSAA HQ

50 11 - Quint (winter)

60 10 - O'Brian

70 10 - Raymond

80 10 - Morgan

90 10 - Jack

a0 10 - Rachel

a0 15 - Rachel Ooze

b0 10 - Hunk

a0 11 - Lady Hunk


If someone knows more characters codes we can complete this list.

Now, let's talk about weapon's tags in raid mode. They are descripted in the weaponTagParam file and the structure is the following:

01 V0 80 02 V1 03 V2 02 V4 03 V5 02 V6 03 ......

V0 is the tag name (3 byte)
Vi (i odd number, 1 byte) is the code of the effect followed by 00 00 00. (4 byte total)
V(i+1) is the corresponding value (4 byte, floating point)

values are always expressed as + bonus %. So, +150% damage will be coded as 150. The only exception are "perforation" (+x = able to pierce x enemies) and "attach scoope" that needs to be zero. Different tags may have different number of bonuses (and penalties), so the lenght os the tag description is variable. Here are the tag codes:

00 00 09 - Short Range
01 00 09 - Long Range
02 00 09 - Easy Grip
03 00 09 - Speed Shot
04 00 09 - Steady Hand
05 00 09 - Speed Load
06 00 09 - Sonic Assist
07 00 09 - Light Weight
08 00 09 - Sonic Assist+
09 00 09 - Short Range+
0A 00 09 - Long Range+
0B 00 09 - Rare "Named" Weapon

Here are the effect codes:

01 damage
02 short range (<4 meters) damage
03 long range (>6 meters) damage
04 Taijutsu damage
05 knife damage
06 stopping power
07 daze
08 critical chance
09 defense *
0A movement speed
0B dodging time
0C (no idea)
0D rate of fire
0E reload speed
0F magazine size
10 perforation
11 hit radius
12 recoil (negative values when you want to decrease the recoil)
13 number of slots
14 scope attached to weapon (must be 0)

*defense: I am not sure of what "defense" means. The google translation of the japanese guide isn't that good. It could be damage reduction but I am not sure. It is one of the hidden values of "easy grip" tag; the japanese guide says +9% defense.

Example: easy grip

01 02 00 09 80 02 04 00 00 00 03 00 00 A0 41 02 05 00 00 00 03 00 00 F0 41 02 09 00 00 00 03 00 00 10 41 02 0F 00 00 00 03 00 00 48 C2 02 0D 00 00 00 03 00 00 70 C1

02 00 09 easy grip code

04 bonus taijutsu damage with value 41 A0 00 00, that is 20 (20%).
05 knife bonus damage with value 41 F0 00 00 (30%)
09 defense with value 41 10 00 00 (9%)
0F magazine size bonus, value C2 48 00 00 (-50%)
0D rate of fire, value C1 70 00 00 (-15%)

So, let's say I want to remove rate of fire -15% and add daze +100%, all I need to do is to chance 02 0D 00 00 00 03 00 00 70 C1 with 02 07 00 00 03 00 00 C8 42 03. This is an easy way to mod tags, I don't know if it is possible to add bonuses or penalties (making strings longer), I haven't tested it.


edit: does anyone know where are weapons and parts values for campaign stored? I would love to mod some campaign stuff!
