Features

• X86 Legacy Emulation - Simulates legacy x86 processor modes and BIOS environments to run 16-bit and 32-bit operating systems in a browser.
• x86 Binary Emulators - Runs 16-bit and 32-bit x86 compatible operating systems directly within a web browser.
• Virtual Storage Managers - Manages virtual disk volumes and image persistence to provide a stable data environment for the guest OS.
• Browser-Based Hardware Emulation - Implements a full x86 hardware simulator including CPU and memory layouts directly in the browser.
• Disk and Mount Management - Attaches bootable media and storage images to the system to enable operating system loading.
• Hardware Component Simulation - Simulates CPUs, memory, and storage devices to execute legacy x86 software without original native hardware.
• Operating System Emulation - Executes 16-bit and 32-bit compatible operating systems using a virtualized x86 architecture.
• Operating System Virtualization - Provides a virtualized environment to load disk images and run complete guest operating systems in a browser tab.
• Browser-Based Virtualization Platforms - Provides a virtualized environment for booting disk images and managing hardware directly in a web page.
• x86-to-Wasm Translation - Implements a just-in-time compiler that translates x86 machine code into WebAssembly for high-performance browser execution.
• x86-to-Wasm JIT Compilation - Uses a JIT compiler to translate x86 instructions into WebAssembly for near-native performance in the browser.
• VM Lifecycle Controls - Provides controls to pause, reset, or resume the emulated machine from a specific point in time.
• Emulated Network Connectivity - Connects an emulated environment to a network via proxies or relays to enable seamless data transmission.
• Emulator Save State Management - Captures the current system condition and memory dumps to save the state of the emulated machine.
• Network Traffic Routing - Directs guest network traffic through custom paths using proxy types and virtual devices.
• Proxy Tunnels - Routes emulated guest network traffic through host-side proxies to provide internet connectivity.
• Hardware Resource Allocation - Configures virtual hardware resources including memory capacity, video memory, and audio settings.
• Virtual Disk Image Booting - Boots guest operating systems from floppy, CD-ROM, or hard disk images using BIOS and kernel files.
• Disk Image Layout Mappings - Maps binary disk images into emulated memory spaces for guest OS storage access.
• Legacy System Preservation - Enables the execution of legacy operating systems and software in modern browsers for preservation.
• Virtual Hardware Customization - Defines emulated memory size, video memory, and boot order to match target hardware requirements.
• Guest-Host File Access - Provides mechanisms to move files between the host browser environment and the emulated guest disk.
• Machine State Serialization - Serializes the entire CPU and memory state into a data blob for saving and restoring execution.
• Machine State Restoration - Captures current machine status and reloads it later to resume execution from the exact same point.
• Processor State Inspection - Allows for the inspection of processor registers and page tables to analyze the internal condition of the emulated system.
