On 1st November 2020 CAPCOM was targeted by known hacker group RagnarLeaks and some source code and private data was leaked to the dark web. This post will only cover source code that was found in the leak, we only support the preservation of old playstation source code.
Information on the RAGNAR malware, that was responsible for compromising Capcom's servers:https://t.co/oZDDbKMQNz
There were four archives leaked, and due to size were split into multiple 7Zip parts.
CAPCOMinr1.7z - No source code (please avoid downloading if you see this file uploaded)
CAPCOMPart2ID.7z - Umbrella Chronicles source code (21.1GB in 3 parts)
Capcom3ID451.7z - Devil May Cry 2 Source code ( 11.2GB in 2 parts)
CAPCOM4_ID442.7z - The Misadventures of Tron Bonne PS1 source code (1.38GB)
The archives released after these (5-7) do not contain any source code unfortunately, so will not be covered in this post.
Archive 8 contains source code for unreleased Resident Evil games and thus are not considered retro and will not be covered here.
Resident Evil Umbrella Chronicles
When the archives have been extracted it creates a folder called Wii_バイオハザード アンブレラクロニクルズ which translates roughly to Wii_ Biohazard Umbrella Chronicles. Biohazard is the Japanese name for Resident Evil.
The source code for Resident Evil Umbrella Chronicles has many empty folders inside it, it is unclear why this is the case, they could have been removed due to space constraints or maybe a copy job was only part way through before it was stopped.
The empty folders will be listed here with their translations just to make you aware of what may have been contained within at some point in time.
The way the files are laid out suggest that this was stored on some sort of external hard drive due to the inclusion of $RECYCLE.BIN and System Volume Information folders.
Folders at the top Level are:
$RECYCLE.BIN - created by Windows OS to hold deleted items (Empty folder)
Recycled - Unsure of purpose but empty
System Volume Information - contains empty restore folders, probably due to unexpected hard drive disconnect causing corrupted files
UC使用フォント - UC fonts used
bioUCリビルド手順 - build environment tutorial
design - design documents for the game (level layouts etc)
サウンド - Sound (Empty folder structure)
バイオ納品 - Bio delivery (Source code folder structure)
企画 - Planning (Empty folder structure)
韓国版 - Korean version
UC fonts used (/UC使用フォント)
As expected by the name this folder contains fonts used in the development of the game i TTF and TTC formats.
It is unclear if these were just used for the game box and manual or if they were also converted to textures for inside the game too.
The fonts included in this folder are:
CHELSEXR.TTF - Chelsey Extended
COMMAEXR.TTF - Commador Extended
DF-ReiSho-W6.ttc - Collection of fonts
EGGOWN__.TTF - Eggo Wide
MLSAX.TTF - Prestige
MLSGW.TTF - Architect
VOGEB___.TTF - Vogel
WKWCHJO.TTF - WKWChongjo
UC build procedure (/bioUCリビルド手順)
This folder contains a tutorial for how to setup a development environment, including Wii SDK, CodeWarrior and CRI SDK for building the source code to Resident Evil Umbrella Chronicles!
Got to hand it to them, the developers of Resident Evil Umbrella Chronicles had good documentation for how to get setup with the codebase. Including installing the Wii SDK, CodeWarrior and the CRI SDK Nice job! #capcomleaks#capcom#wiipic.twitter.com/ntSm1fp4dz
The design folder contains a bunch of game design document for Umbrella Chronicles!
This includes top down drawings of each of the maps with all the areas of interest mapped such as where to collect items. These files are named like so:
bioUC_scenario*_*_* // e.g bioUC_scenario0_0_1
This folder also contains some interesting files with the following file formats:
.EMDL - AutoDesk Softimage Export Model
.RMDL - Revolution Model (Wii 3D Model)
.RTSA - Revolution Texture Animation (Wii)
.RTEX - Revolution Texture format
.SCN (Scene format)
.BRRES - Common archive format for Wii assets (models etc)
Some of these file formats are covered in our Wii file formats page:
This folder contains the following sub folders inside it:
BioUC_2D_Kor - 2D assets
RECYCLER - empty tree
bioUCリビルド手順 - tutorial for setting up development environment (the same content as the folder at the root level)
bioUC韓国版テキスト - bioUC Korean version text
バイオ納品 - Source code
2D Assets (/韓国版/BioUC_2D_Kor)
This folder mostly contains TGA images for all the textures and images in the game.
The assets are organised into a number of folders:
atract - Wii warning messages and starting screens (abstract?)
binary - contains tpl, brlan and brlyt format files
dialog - tga/rlan/rlyt image assets for dialogs
doc - spreadsheets of text for localisation
game - empty tree
gameover - empty tree
icon_banner_kr - empty tree
option - empty tree
pause - empty tree
result - empty tree
saveload - empty tree
select - empty tree
title - empty tree
File formats for 2D assets include:
BRLAN (Binary Revolution Layout AnimatioN) - Wii format for title animations (Binary)
BRLYT (Binary Revolution LaYouT) - Wii format for layout
TPL (Texture Palette Library) - Wii format for texture palettes (colours)
RLAN (Revolution Layout AnimatioN) - Wii format for title animations (XML)
RLYT (Binary Revolution LaYouT) - Wii format for layout (XML)
It looks like this folder was half way through copying when it stopped, as it was probably copying alphabetically, as soon as it got to the doc folder it stopped copying, so the rest of the folders are empty trees.
Korean version text (/韓国版/bioUC韓国版テキスト)
This folder contains fonts and text messages used throughout the game to be localised from Japanese into Korean.
The only file with messages to be translated is called mes_ko.xls and contains thousands of messages (2000+) in Japanese with their Korean counterparts. if you have ever wondered how games get localised into other languages then this is the document you should check out.
The fonts are separated into two of folders:
Ksマッピング - KS mapping (Korean)
WKBGHYSO.TTF
WKLYESO.TTF
WKWCHJO.TTF
WKYESO.TTF
S-jisマッピング - S-JIS mapping (Japanese)
CGBGHyso.ttf
CGLYeso.TTF
CGWCHJO.TTF
CGYESO.TTF
Korean Source code (/韓国版/バイオ納品)
For an overview of the Source code folder see the next section as the only source code we have is for the Korean version, for some reason the other versions were never copied over in the leak.
Source Code (/バイオ納品 and /韓国版/バイオ納品)
The folder name roughly translates to Bio Deliverables and should contain the source code and tools developed for the game.
However there is one important point about this folder, it is located in two places in the leak, one is mainly just the empty folder structure and the other is the real deal.
The strange thing is the one with the actual content is actually in the Korean version folder (/韓国版/バイオ納品).
In the root version it is mainly an empty folder structure but the buildtool does contain some files.
Files only in the Root version (/バイオ納品)
There are a few files that are only located in the /バイオ納品 folder despite the majority of it being an empty folder structure. They are all located in /バイオ納品/buildtool/buildtool/ and have the following folders:
CRI_SDK - CRI Middleware SDK
CodeWarrior - CodeWarrior + Plugins + License
DevelopmentTools - Wii Development tools
MasteringTools - Tools for Wii game publishing
NintendoWareForRevolution - NintendoWare tools and runtime libraries for Wii
RevolutionSDK - Wii SDK
These are all official software development kit files from Nintendo and CRIware used in many 1st & 3rd party Wii games.
Since these are not Capcom specific they will be covered in a future post.
Korean version source code (/韓国版/バイオ納品)
The rest of this section will discuss the korean version of the source code. It contains the following files and folders:
bioUC - C/C++ source code
bioUCscript - Game script files (lua etc)
buildtool - Nintendo SDK Tools
readme.txt - Japanese document outlining the structor of the source code
tool - custom tools created by Capcom
北米著作権登録 - North American copyright registration
North American copyright registration (北米著作権登録)
This is a very strange folder indeed, the translated name might make you think of some sort of legal documents to the North American copyright office.
However there are two files in this folder and they are not what I would expect at all:
ending.doc
title.doc
Just judging by the names you might think it is the story of the game, but if you actually open the documents you will see they are both C/C++ source code files in MS Word format.
Who knows why these exist in this format, very odd indeed!
Nintendo SDK Tools (/韓国版/バイオ納品/buildtool)
As expected this folder contains all the Software development kits and tools from outside of Capcom. It is split into a number of folders:
CRI_SDK - CRIware SDK
CodeWarrior - Metrowerks Codewarrior
DevelopmentTools - Wii tools created by Nintendo
MasteringTools - Wii Mastering tools created by Nintendo
NintendoWareForRevolution - NintendoWare tools and runtime libraries for Wii
RevolutionSDK - Official Wii SDK

音周り - Sound
The file aiscript.txt is facinating, it describes the custom scripting language they implemented for the movement of the AI characters. It is based on the Forth programming language and they called it bioForth. It is well worth a read if you can translate it.
Following on from aiscript.txt you should also read ode_script.txt as it is based on the same custom scripting language. In this case it is used for Open Dynamic Engine physics object creation!
Source Code files (/bioUC/Src)
Note that the actual development team was outside of Capcom in a company called Cavia so you will see the Cavia copyright at the top of most source files.
This folder contains:
Common - common code used for multiple games
Game - main game code specific to this game
Test - test code for collisions/sounds etc
Tool - source code to the custom tools they created
Tool Source code (/bioUC/Src/Tool)
The Tool folder is split into 3 different categories depending where the tool is run:
Wii - Tools that are run on the Wii itself
Win32 - Windows tools
Plugin - Plugin for Softimage XSI 3D modelling tool
There is only one plugin for Softimage XSI and it is for exporting collision data from a Softimage scene. it is aptly named CollisionDataExporter and contains the full Visual Studio project.
The Wii Tools that were created by Capcom are:
AgingTask
BgObjViewer
CollisionViewer
ColorBar

Devil May Cry 2 Source code (Capcom3ID451.7z)
When the archive is extracted you get a folder called “02_デビルメイクライシリーズ” which simply translates to “02_Devil May Cry Series”, this folder contains two children:
PS2_デビルメイクライ2 - PS2_Devil May Cry 2
マスター画像 - Master image (empty folder)
Looking into the one non-empty folder you will find a few files and folders:
PS2_デビルメイクライ2【収納されていたパッケージ画像2】.pdf - Photo of the top of the storage box that contained the builds
PS2_デビルメイクライ2【収納されていたパッケージ画像3.pdf - Photo of the side of the storage box that contained the builds
PS2_デビルメイクライ2【最終バックアップディスク1】.ISO - Final Backup Disc 1
PS2_デビルメイクライ2【最終バックアップディスク1】.html - Final Backup Disc 1
PS2_デビルメイクライ2【最終バックアップディスク1】.pdf - Final Backup Disc 1
PS2_デビルメイクライ2【最終バックアップディスク2】.ISO - Final Backup Disc 2
PS2_デビルメイクライ2【最終バックアップディスク2】.html - Final Backup Disc 2
PS2_デビルメイクライ2【最終バックアップディスク3】.ISO - Final Backup Disc 3
PS2_デビルメイクライ2【最終バックアップディスク3】.pdf - Final Backup Disc 3
PS2_デビルメイクライ2【最終バックアップディスク4】.ISO - Final Backup Disc 4
PS2_デビルメイクライ2【最終バックアップディスク4】.html - Final Backup Disc 4
マスター画像 - Master Image (empty folder)
Note the naming of the files might be a little confusing, there are four unique discs (ISO files) here. Rather than 4 different versions of the same disc as I initially thought when viewing the folder.
A really cool but unexpected fact about this folder is the inclusion of the photos of where the builds were stored, including the cardboard box which has DMC2 images stuck to it.
They are all stored in PDF format for some reason even although they only contain one image. Also contained in pdf format is photos of the CD inside the jewel case.
The HTML files in this folder are also quite interesting, they seem to be a list of differences between what is presumably the Master Image and the specific backup discs.
This leaves the ISO image files which is exactly where you will find the source code for the game, so lets dive in!
A backup of a disk containing DMC2 code was found in the leak.
Original is probably in cold storage, sitting at some undisclosed location.
Each disc contains a subset of a single large build, this is due to the limited storage size of DVD discs.
So there is a readme.txt file at the root of each DVD which lists the final build structure when you merge all the discs together.
Disc 1 - PS2 SDKs and 3rd party libraries
When Disc 1 has been mounted it has the following contents:
china - library for Chinese version
cri - CRI middleware (ADX/Sofdec/MWSFD)
cw - CodeWarrior 3.03J
cygwin - cygwin 1.1.x
readme.txt - details about the contents of all theDVDs
sce - Official PS2 SDK
si - SoftImage XSI data
Disc 2 - Source Code
When Disc 2 has been mounted it has the following contents:
blood_type.txt - Blood Type Meta Data
data - data for mastering the DVD disc of the game
devil2.bat - just sets environment variables for building the game
dipsw.dat - Maybe something to do with DIP switches on the dev hardware?
effect.txt - Notes about the player and the enemy’s flying sand smoke effect
enemy.txt - some sort of meta data related to player and enemies
filename.txt - this looks like a template for creating new files
inst.bat - install batch script that copies and deletes data
keepflag.txt - meta data about bonus orbs
makefile - the main makefile for the project
makerom.txt - notes about creating the ISO image
module.lst - list of IOP modules (IRX files)
mwlib - CRI middleware library files
pack.bat
pget.bat - batch script for copying data then packing it
probar.txt - notes about the loading processing bar
prog - C/C++ source code
project - CodeWarrior project files data
roma.bat - Copy files for America
romc.bat - Copy files for China
rome.bat - Copy files for Europe
romj.bat - Copy files for Japan
romk.bat - Copy files for Korea
scrchpad.txt - scratchpad memory notes
setting.bat - possibly copies ELF file to dev hardware
uninst.bat - deletes AutoModelista files (probably copied from that games project files and forgotten to be updated)
One surprisingly interesting file is probar.txt which lists the different colours the loading progress bar has and what it is actually doing when it has that colour!
Disc 3 - Misc
When Disc 2 has been mounted it has the following contents:
camera - Camera intermediate data
ccz - For creating the ISO IMAGE
char - Textures - TIM2, IPU data
demo - content used for Demo Disc version
doc - Text files for localisation
movie - contains movie files that wouldn’t fit on Disc 4
orb - Set orb intermediate data
set - Enemy set intermediate data
sound - Sound data
stage - Terrain intermediate data
tools - Tools
Disc 4 - Movie files
This DVD only contained the movie files which would have been located at /devil2/movie in the original build.
The contents of the movie folder are as follows:
Jiware512.zip
billboss512.zip
cg_00d.mcj - op/dante video metadata
cg_00l.mcj - op/lucia video metadata
cg_01.mcj - matihe512 video metadata
cg_02.mcj - billboss512 video metadata
cg_03.mcj - hliport512 video metadata
cg_04.mcj - tower512 video metadata
cg_05.mcj - gisiki512 video metadata
cg_06.mcj - mon512 video metadata
cg_07.mcj - Jiware512 video metadata
cg_08.mcj - staff video metadata
cg_09d.mcj - next dante video metadata
cg_09l.mcj - next lucia video metadata
devil2.mcl - INI file containing paths for all the .MCJ files
gisiki512.zip
hliport512.zip
matihe512.zip
mon512.zip
movie.lst - seems to contain meta data describing the .mdj files
next.zip
staff.zip - Ending credits video of the game
tower512.zip
The .MCJ files seem to have been created by CRI Sofdec CRAFT, these are video files in the CRI Sofdec format. The sofdec format is based on MPEG-2 but has support for CRI’s ADX audio codec.
These files are all brought together in the plain text ini files called devil2.mcl.
The zip files contain bitmap (BMP) files for each frame of the video! As you would expect these vip files are huge because of it.
Note that Disc 3 also contains 3 Movie archives which couldn’t fit on the Disc 4 folder:
op/dante.zip
op/lucia.zip
op/国別512.zip - Country?
The Misadventures of Tron Bonne (CAPCOM4_ID442.7z)
The root folder is called PS_トロンにコブン which is the Japanese name for the game plus the PS_ prefix for Playstation. It contains three sub folders inside it:
北米版 - North American Edition
PAL版 - PAL version (Europe)
国内版 - Domestic version (Japan)
Plus the source code of "The Misadventures of Tron Bonne" (screenshot not mine): pic.twitter.com/eutXjxgjel
The Master ROM image folder contains an .img/.cue file combo that is the disc they pressed for PAL regions, you should be able to play this in the PS1 emulator of your choice.
It is unconfirmed if there are any minor differences between this and the retail disc that players would buy, but it is unlikely.
North American Version (/北米版)
There are four folders in the North American version:
ﾏｽﾀｰﾛﾑｲﾒｰｼﾞ - Master ROM image
disc1 - NA Source Code
disc2 - Tools developed by matsuda and shingaki
disc3 - NA Tools
ﾏｽﾀｰﾛﾑｲﾒｰｼﾞ - Master ROM image
The Master ROM image folder contains an .img/.cue file combo that is the disc they pressed for North America, you should be able to play this in the PS1 emulator of your choice.
It is unconfirmed if there are any minor differences between this and the retail disc that players would buy, but it is unlikely.
Japanese Version (/国内版)
The Japanese version contains more folders than the other two due to it containing some development tools.
tools - tools developed by each member of the development team
library - development software such as Multi-ICE
ﾏｽﾀｰﾛﾑﾃﾞｰﾀ - Master ROM data
pocket - Pocketstation source code
psx - PS1 source code and assets
Tools (/国内版/tools)
Each folder belongs to a member of the development team:
