GTA Vice City — HTML5 Port (DOS Zone)

Web-based port of GTA: Vice City running in browser via WebAssembly.

Requirements

• Docker or Python 3.8+ or PHP 8.0+
• Dependencies from requirements.txt

Quick Start

1. Clone the repository:

   git clone https://github.com/Lolendor/reVCDOS.git
   cd reVCDOS

2. Configure Assets (Optional):

   By default, the project uses the DOS Zone CDN. For local hosting, download and place assets in (see structure):

   • Resources: vcsky/fetched/ (or fetched-ru/) — data, audio, anim, models folders.
   • Binaries: vcbr/ — .wasm.br and .data.br files for your chosen language.

3. Launch the Application: Choose one of the setup methods below:

   • Docker (Recommended for most users) — fast and isolated.
   • PHP — Simply upload the folder to your web server (FTP/Hosting).
   • Manual Installation — for development and customization.

Setup & Running

Option 1: Using Docker (Recommended)

The easiest way to get started is using Docker Compose:

VCSKY_CACHE=1 VCBR_CACHE=1 docker compose up -d --build

To configure server options via environment variables:

# Set port, enable auth and custom saves
IN_PORT=3000 AUTH_LOGIN=admin AUTH_PASSWORD=secret CUSTOM_SAVES=1 docker compose up -d --build

Environment Variable	Description
OUT_HOST	External host (default: 0.0.0.0)
OUT_PORT	External port (default: 8000)
IN_PORT	Internal container port (default: 8000)
AUTH_LOGIN	HTTP Basic Auth username
AUTH_PASSWORD	HTTP Basic Auth password
CUSTOM_SAVES	Enable local saves (set to 1)
VCSKY_LOCAL	Serve vcsky from local directory (set to 1)
VCBR_LOCAL	Serve vcbr from local directory (set to 1)
VCSKY_URL	Custom vcsky proxy URL
VCBR_URL	Custom vcbr proxy URL
VCSKY_CACHE	Cache vcsky files locally while proxying (set to 1)
VCBR_CACHE	Cache vcbr files locally while proxying (set to 1)

Option 2: Local Installation

1. Install Python dependencies:

pip install -r requirements.txt

2. Start the server:

python server.py --vcsky_cache --vcbr_cache

Server starts at http://localhost:8000

Option 3: Shared Hosting on PHP (No installation)

If you want to run the game from a hosted environment with PHP 8.0 or above, just copy the contents of this repo to your desired hosting By default the index.php and .htaccess will get the job done.

Server Options

Option	Type	Default	Description
--port	int	8000	Server port
--custom_saves	flag	disabled	Enable local save files (saves router)
--login	string	none	HTTP Basic Auth username
--password	string	none	HTTP Basic Auth password
--vcsky_local	flag	disabled	Serve vcsky from local vcsky/ directory
--vcbr_local	flag	disabled	Serve vcbr from local vcbr/ directory
--vcsky_url	string	https://cdn.dos.zone/vcsky/	Custom vcsky proxy URL
--vcbr_url	string	https://br.cdn.dos.zone/vcsky/	Custom vcbr proxy URL
--vcsky_cache	flag	disabled	Cache vcsky files locally while proxying
--vcbr_cache	flag	disabled	Cache vcbr files locally while proxying

Examples:

# Start on custom port
python server.py --port 3000

# Enable local saves
python server.py --custom_saves

# Enable HTTP Basic Authentication
python server.py --login admin --password secret123

# Use local vcsky and vcbr files (fully offline mode)
python server.py --vcsky_local --vcbr_local

# Use custom proxy URLs
python server.py --vcsky_url https://my-cdn.example.com/vcsky/ --vcbr_url https://my-cdn.example.com/vcbr/

# Cache files locally while proxying (hybrid mode) (recommended)
python server.py --vcsky_cache --vcbr_cache

# All options combined
python server.py --port 3000 --custom_saves --login admin --password secret123 --vcsky_local --vcbr_local

Note: HTTP Basic Auth is only enabled when both --login and --password are provided.

Note: By default, vcsky and vcbr are proxied from DOS Zone CDN. Use --vcsky_local and --vcbr_local flags to serve files from local directories instead.

Note: Use --vcsky_cache and --vcbr_cache to cache proxied files locally. Files are downloaded once and served from local storage on subsequent requests.

Example: Enter mykey or 12345 — saves will be stored as mykey_vcsky.saves or 12345_vcsky.saves.

Controls (Touch)

Touch controls appear automatically on mobile devices. Virtual joysticks for movement and camera, context-sensitive action buttons.
