    emuiibo

    emuiibo

    Virtual amiibo (amiibo emulation) system for Nintendo Switch

    Virtual amiibo (amiibo emulation) system for Nintendo Switch. A virtual amiibo is detected by emuiibo based on two aspects: a amiibo.json and a amiibo.flag file must exist inside the virtual amiibo's folder mentioned above. If (for whatever reason) you would like to disable a virtual amiibo from being recognised by emuiibo, just remove the flag file, and create it again to enable it. While old emuiibo formats are supported and converted to the current format (see above), it is strongly suggested to, unless bin dumps might be indispensable, emuiigen be used, our PC utility designed to create and edit virtual amiibos.

    MAME

    MAME

    MAME is a multi-purpose emulation framework

    MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus. The MAME project as a whole is distributed under the terms of the GNU General Public License, 2 (GPL-2.0), since it contains code made available under multiple GPL-compatible licenses.

    Play!

    Play! - PlayStation2 Emulator

    Play! is an open-source cross-platform emulator for Sony’s PlayStation 2 that aims to run PS2 games on a wide range of modern systems including Windows, macOS, Linux, Android, iOS, and web browsers by implementing core PS2 hardware functionality in software. It emulates primary components like the Emotion Engine CPU and graphics synthesizer, translating game code and hardware calls into host system operations, while providing users with controls to load disc images, manage states, and configure rendering options. Because the PS2’s architecture is complex and proprietary, Play! pursues compatibility incrementally, with many titles playable to varying degrees and an active compatibility tracker detailing individual game status. The project supports optimizations such as JIT code generation on compatible platforms to improve performance and offers a broad set of build targets so developers and users can experiment with different back ends and environments.

    FEX

    FEX

    A fast usermode x86 and x86-64 emulator for Arm64

    FEX allows you to run x86 and x86-64 binaries on an AArch64 host, similar to qemu-user and box86. It has native support for a rootfs overlay, so you don't need to chroot, as well as some thunklibs so it can forward things like GL to the host. FEX presents a Linux 5.0 interface to the guest, and supports both AArch64 and x86-64 as hosts. FEX is very much work in progress, so expect things to change. FEX has been tested to build and run on ARMv8.0, ARMv8.1+, and x86-64(AVX or newer) hardware. ARMv7 and older x86 hardware will not work. Expected operating system usage is Linux. FEX has been tested with Ubuntu 20.04, 20.10, and 21.04. Also Arch Linux. AArch64 hosts require a rootfs for running applications.

    DS emulator, sorta

    melonDS aims at providing fast and accurate Nintendo DS emulation. While it is still a work in progress, it has a pretty solid set of features. Firmware boot (not direct boot) requires a BIOS/firmware dump from an original DS or DS Lite. DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly. DS BIOS dumps from a DSi or 3DS can be used with no compatibility issues.

    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.

    Clock Signal

    Clock Signal

    A latency-hating emulator of: the Acorn Electron, BBC Micro

    Clock Signal also known as Clock Signal, is a highly sophisticated multi-system emulator designed with a strong emphasis on minimizing latency and maximizing authenticity in signal reproduction rather than relying on post-processing shortcuts. Its defining philosophy is to make emulation “invisible” to the user, meaning software can be launched directly without requiring manual configuration of machines, disks, or hardware profiles. The emulator supports a wide range of classic systems, including the Apple II, Atari 2600, ZX Spectrum, MSX, and early Macintosh computers, all within a unified architecture. One of its most technically distinctive features is its signal-processing-based rendering pipeline, which simulates original video outputs such as composite signals instead of simply drawing pixels, resulting in highly accurate visual artifacts. CLK also prioritizes extremely low latency by decoupling audio and video pipelines and leveraging modern display capabilities.
