Citra Emulator

Citra Emu

Citra is an open-source emulator for the Nintendo 3DS capable of playing many of your favorite games.
The nightly build of Citra contains already reviewed and tested features. If you require support with the installation or use of Citra, or you want to report bugs you should use this version. This version is still in development, so expect crashes and bugs.

The Canary build of Citra is the same as our nightly builds, with additional features that are still waiting on review before making it into the official Citra builds. We will not provide support for issues found only in this version. If you believe you’ve found a bug, please retest on our nightly builds. This version is still in development, so expect crashes and bugs.

The Citra updater provides a easy interface to install, update and manage Citra. Unless you know what you are doing, this is likely what you are looking for. Citra currently does not support Android or iOS, only desktop x64 systems.

Multiple Arcade Machine Emulator

M.A.M.E.

MAME is an acronym for Multiple Arcade Machine Emulator. The intent of this emulator is preservation; the ability to play games is considered a “side-effect.” MAME supports thousands of classic arcade games, although not all of them are playable.
For legal reasons, this site does not contain nor link to ROMs. But MAME is an exception, as the “ROM site” in question is none other than the Internet Archive (archive.org). You can find the game ROMs, BIOS ROMs and all other files needed to play games in the MESS and MAME collection on their site as both direct downloads and torrent files. Be aware that a complete collection can take a lot of disk space (over 50GB, and you need double that to extract the archive that holds all the ROMs). After downloading you can place game and BIOS ROMs in the “roms” subfolder inside the MAME folder.
MAME handles ROMs a little different in that you do not have to unzip every individual game. MAME can open them as ZIP files. The reason for this is that arcade ROMs tend to consist of multiple files.

Sega NAOMI 2

Sega NAOMI 2

The Sega NAOMI 2 is an arcade board developed by Sega and is a successor to Sega NAOMI hardware. Since it uses similar NAOMI architecture (but significantly beefed up), it is also fully backwards compatible with its predecessor.
The NAOMI 2 is significantly more powerful than the NAOMI, including a dual CPU setup, new T&L GPU, dual rasterizer GPU, increased memory, and faster bandwidth. This leads to games with much more polygons than a NAOMI game, rendered at much faster speeds, while the new T&L GPU adds advanced lighting and particle effects. It was also more affordable than the very expensive (and difficult to program) Sega Hikaru arcade system that preceded it.
As with the NAOMI, the NAOMI 2 was also available in GD-ROM and Satellite Terminal variants. It was Sega’s last proprietary arcade system board; subsequent Sega arcade boards have been based on console and PC hardware.

Reicast – A Dreamcast Emulator

Play your Dreamcast games on android. In HD.

Available on the Play Store, OUYA, and OpenPandora

Reicast Dreamcast Emulator is an emulator for the last SEGA gaming console, the legendary Dreamcast console, which is perfectly designed to work with Android operating system. So, you will be able to play some of the most emblematic games in history, such as Shenmue, Jet Set Radio or Space Channel 5, on your mobile phone or tablet.

Before starting to play, you have to manually create the folder where you want to save the Dreamcast BIOS. In fact, you have to download the BIOS separately and save it to your Android device’s memory. Only then will you be able to use the emulator.

Reicast Dreamcast Emulator doesn’t have any configuration options at all. You just have to add the image of the game to any folder on your Android device and select it. The file will execute in seconds and you can start playing.

Reicast needs the dreamcast bios and game images to work

Sega Dreamcast

The Sega Dreamcast (ドリームキャスト) is a home video game console manufactured by Sega as a successor to the Sega Saturn. It was originally released in November 1998, becoming the first machine to be released in what is now known as the sixth generation of video game consoles, sharing a platform with the PlayStation 2, Nintendo GameCube and the Xbox.
The Dreamcast is a small, white box with aesthetics designed to appeal to a wide-ranging audience. It was envisioned as an “128-bit” “super console”, designed to leapfrog “32-bit” and “64-bit” contemporaries in the form of the PlayStation and Nintendo 64, respectively (although from a technical standpoint, its main processor deals in 32-bit or 64-bit instructions, with the 128-bit figure coming from the graphics hardware). Incidentally the Dreamcast was the last home console to use “bits” as a selling point, with processing capabilities now typically measured in other ways.

Demul

Demul is a Sega Dreamcast emulator able to play commercial games. Please check the official website for a compatibility list.
DEmul, a Dreamcast emulator which also emulates the arcade boards of Naomi 1, Naomi 2, Hikaru, and Atomiswave.

FS-UAE Amiga Emulation

FS-UAE includes an easy-to-use graphical configuration program which allows you to enjoy FS-UAE and Amiga emulation without writing configuration files.
UAE is a computer emulator which emulates the hardware of the Commodore Amiga range of computers. Released under the GNU General Public License.
UAE has been ported to many host operating systems, including Linux, macOS, FreeBSD, DOS, Microsoft Windows, RISC OS, BeOS, Palm OS, Android, the Xbox console, the PSP, PSVita and GP2X handhelds, iOS, the Wii and Dreamcast consoles, and even to AmigaOS, MorphOS and AROS.

nullDC

nullDC is an open source Sega Dreamcast and NAOMI emulator for Windows, developed by drk||Raziel (currently under the nickname skmp) and ZeZu. It was released under the MIT license.

nullDC requires DirectX 9.0c, Visual C++ runtime libraries and optionally WinPcap for modem emulation. BIOS files are also needed. It has a plugin architecture, with several alternative implementations (some ported from Chankast) for graphics, sound, reading games burned to CD-ROMs (it cannot read GD-ROMs directly) or disk image files, memory cards, etc.

Atomiswave

Atomiswave Sammy Corporation

The Sammy Atomiswave is an arcade board created by Sammy, built around the Sega Dreamcast and NAOMI hardware architecture. The hardware is fairly similar to a retail Dreamcast, but has twice the VRAM and four times the audio RAM. Despite this upgrade, it still has less power and memory than the NAOMI. Games can connect to the Internet using either the standard 56k system or through “AW-Net” (these need to be investigated — TODO).
The Atomiswave is a custom arcade system board and cabinet from Sammy Corporation. It is based on Sega’s NAOMI system board (thus it’s common to see the “Sega” logo on its boot up screen). The Atomiswave uses interchangeable game cartridges and the cabinet’s control panel can be easily switched out with different control sets, including dual joysticks, dual lightguns and a steering wheel.
With the retirement of the aging Neo Geo MVS system, SNK Playmore chose the Atomiswave as its next system to develop games for. In a contract with Sammy, SNK Playmore agreed to develop five games for the Atomiswave system. Metal Slug 6 was SNK Playmore’s fifth game for the Atomiswave, after which SNK moved on to a Taito Type X2 arcade board.
