    MAME4droid

    MAME4droid

    MAME Android Emulator.

    MAME4droid (0.139u1) is developed by David Valdeita (Seleuco), port of MAME 0.139u1 emulator by Nicola Salmoria and TEAM. MAME4droid (0.139u1) emulates arcade games supported by original MAME 0.139u1. This MAME4droid version is targeted to Dual-Core devices, because it is based on a high specs 2010 PC MAME build. Anyway don't expect arcade games of the 90 to work at full speed. With some games that are really bad optimized (like outrun or mk series) you will need at least a 1.5 ghz dual-core device (Cortex A15). This is related to MAME build used, since it is targeted to high specs PC's as i said before. This version emulates over 8000 different romsets. Please, try to understand that that with that amount of games, some will run better than others and some might not even run with MAME4droid. Please, don't email me asking for a specific game to run.

    QEMU

    QEMU

    iPhone 11 emulated on QEMU

    QEMU is a specialized fork of the QEMU emulator designed to emulate Apple iPhone hardware, particularly devices based on the T8030 chip such as the iPhone 11. It extends QEMU’s general-purpose machine emulation capabilities by introducing support for Apple-specific hardware components and boot processes. The project enables researchers to boot and run versions of iOS, including the ability to restore firmware images and interact with the system through debugging tools. It relies on dynamic binary translation and system-level emulation to simulate the ARM-based architecture used in modern iPhones. Due to the complexity of Apple’s ecosystem, the emulator requires extensive patching of the kernel and firmware to function correctly, making it primarily a research and experimentation tool. It has been used in security research contexts to explore iOS internals, including kernel behavior and system services.

    mGBA

    mGBA

    mGBA Game Boy Advance Emulator

    mGBA is a high-performance, open-source emulator designed to accurately replicate the behavior of the Game Boy Advance hardware while maintaining fast execution across a wide range of devices. The project was created with the goal of improving both accuracy and speed compared to earlier emulators, achieving a balance that allows games to run reliably even on lower-end systems. It supports not only Game Boy Advance titles but also Game Boy and Game Boy Color games, making it a versatile multi-generation emulator. The architecture is written in C and focuses on precise hardware emulation, including CPU timing, graphics rendering, and audio output, which are essential for compatibility with a wide range of games. It includes multiple frontends such as Qt for a full graphical interface and SDL for lightweight usage, giving users flexibility depending on their environment.

    v86

    v86

    x86 PC emulator and x86-to-wasm JIT, running in the browser

    v86 is an open-source x86 PC emulator that runs entirely in the browser using WebAssembly for near-native performance. It translates x86 machine code into WebAssembly at runtime, enabling users to boot and run full operating systems without installing anything locally. The emulator supports a wide range of legacy systems, including Linux, Windows 95/98/2000, FreeDOS, and various experimental OSes. It simulates essential hardware components such as CPU, memory, VGA graphics, sound cards, network adapters, and storage controllers. Designed for both experimentation and embedding, v86 can be integrated into web apps or used as a standalone virtual machine environment. Overall, it provides a powerful way to explore operating systems, retro computing, and low-level system behavior directly from a web browser.

    The Bitdefender disassembler

    The Bitdefender disassembler

    bddisasm is a fast, lightweight, x86/x64 instruction decoder

    The Bitdefender disassembler is a highly optimized, lightweight x86/x64 instruction decoder designed for security, reverse engineering, and low-level systems analysis. It focuses on decoding machine instructions with high precision while providing detailed metadata about each instruction, including operands, access modes, CPU flags, and feature requirements. Unlike many disassemblers, bddisasm is built with zero dynamic memory allocation and no external dependencies, making it extremely portable and suitable for constrained environments such as kernels, hypervisors, and embedded systems. The project also includes a companion component called bdshemu, which provides a minimal instruction emulator capable of analyzing shellcode-like behavior in a controlled environment. Its performance is a key strength, achieving millions of decoded instructions per second while maintaining thread safety and deterministic behavior.
