Cellphone emulators

From Emulation General Wiki

Before the smartphones we know today were staples of mainstream culture, mobile phones, and their technology were pretty rudimentary and often relied on apps made in Java seeing as the language was designed to be portable (though Windows Mobile and Symbian were also somewhat popular as proto-smartphone platforms of choice). This didn't keep games from being developed for these platforms. Casual simplistic games and rip-offs of retro franchises thrived, but it attracted some genuinely fun games that forever remained obscure, such as those from Gameloft.

The situation is quite different in Japan where mobile hardware was much more developed, only loosely Java-based, and major video game developers were much more invested in creating unique and high-quality content that's most obscure and unpreserved, let alone emulated, today. Those are the very different Galapagos mobile phones (like NTT DoCoMo i-mode, DeNa, RoID...). Some of these games got ported to the inferior Western hardware but these are in the tiny minority.

.JAR files of Java-based non-Japanese cell phones can be still found online with some effort, namely on WAP sites offering (pirated) mobile content e.g.

Java ME mobile phones

A free cross-platform language capable of working in devices with highly reduced capabilities. It was basically Java stripped down to the bare essentials. While originally not intended for games (until its more advanced game-oriented API came), it became the de facto market standard for cell phone gaming - due in no small part to the SDK being free and without licensing costs.

Mascot Capsule 3D is 3D graphics on Java ME phones, more specifically Sony Ericsson Java phones. It was mainly used by Fishlabs Games (nowdays Deep Silver Fishlabs) for games like Asphalt 3 3D, Galaxy on Fire, Blades & Magic or Robot Alliance, among others.

Sony Ericsson (Sony Mobile) phones. That used Mascot Capsule 3D (MBAC / MTRA) technology, which makes launching / modding games for SE 3D even more affordable!. So far it was only emulated in the Sony Ericsson SDK (JDK really) for Windows, which is anything but a user-friendly emulator (and it doesn't work on x64, no way). But now a certain JL-Mod has implemented it in the best Java ME emulator ever (light years away from the popular KEmulator), J2ME Loader for Android.

Mascot was used by multiple studios but the one who made the most use of this standard was the relatively popular Fishlabs Games studio, using its Abyss Engine. You will remember it from other movies such as: Galaxy on Fire, Heli Strike, Robot Alliance, Tank Raid, etc.

The Mascot should not be confused with normal JSR184 implementations. Normally the Mascot was exclusive to Sony Ericsson and Samsung, Nokia versions (which were generally brutally inferior to Sony Ericsson, in any Java ME standard) used to use normal JSR184, as for example in Worms Forts or Asphalt 3 3D.


Currently, J2ME Loader which is able to run most of the J2ME games which also run natively 3D games, this emulator is unable to run Mascot Capsule 3D V3 games, keeping in mind that JL-Mod has run MC3D V3 games. KEmulator and FreeJ2ME should suffice for most games, but there's a minority of games making use of obscure vendor-specific APIs supported only on their respective SDK tools. Given the scarcity of such tools, this list aims to comprehensively list the available ones for convenience.

  1. Run J2ME apps on BlackBerry 10 - J2ME loader (and possibly PlayBook through PPSSPP)
  2. Only available as a libretro core (e.g. RetroArch).
FreeJ2ME — Free and open-source
Has fewer features than KEmulator, but better compatibility. It's recommended for games that don't work with KEmulator. It has an optional libretro core and development is active. Games that freeze on KEmulator, such as Wolfenstein RPG and Doom 2 RPG, run on FreeJ2ME with no issues, although compatibility and accuracy are not as good as J2ME Loader. Some games run too fast and require tinkering with the frame rate options. No 3D support.
KEmulator — Closed-source
Has more features and compatibility than other ones, as well as 3D emulation (Compared with SJBoy and Midp2exe, KEmulator better performance). Has support for custom resolutions and full screen (View/Options). You can even set a proxy server for mobile Java apps that connect to the internet under options. Requires Java Runtime Environment installed. It is a recommended emulator if you're on a Windows PC, although some games (such as Wolfenstein RPG and Doom 2 RPG) freeze indefinitely on the loading screen. Last update was in 2012.
Nokia SDKs
A set of different device emulators released by Nokia along with their J2ME SDKs. Keyboard bindings are not friendly for playing games. Some of them are buggy. The Nokia 3410 SDK emulator is capable of running some ancient black&white J2ME games no other emulator can.
Sony Ericsson SDKs
Device emulators released by Sony Ericsson along their J2ME SDKs. Some of them have support for Mascot Capsule V3 3D APIs. Can run some games at better framerates than the original devices
Siemens SDKs
Device emulators released by Siemens along their J2ME SDKs. Can run some older games that depend on old Siemens APIs
Motorola SDKs
J2ME development kits released by Motorola. Can run some older games that depend on Motorola-specific APIs
Motorola iDEN SDK
J2ME development kit released by Motorola. Can run some older games that depend on iDEN-specific APIs
Haves support for some obscure vendor-specific APIs that other emulators don't support.
More compatible than MidpX. Can take snapshots. More resolutions (but still buggy). Appears to run correctly some older games FreeJ2ME and KEmulator don't and available for Windows only (You can also run it using Wine on Linux and Mac).
Mini soyo
Experimental emulator from the SJBoy authors. Appears to properly emulate transparency on older games making use of Nokia APIs. To open a game, drag and drop the JAR file onto the MiniSoyo window.
One of the older emulators. Fixed low resolution (176x220) and compatibility, no handler app support. The installer may contain adware.
Emulator from a company that used to develop solutions to allow users to try J2ME game demos on their computer before purchasing them. Doesn't have any known advantageous features. Requires : JRE.
N-Gage Cool! — Paid ($)
N-GAGE COOL! the ability to compare the two mobile game decks side-by-side having the very different and unique gameplay experience of both N-GAGE QD and N-GAGE.
MicroEmulator — Free and open-source
MicroEmu is a pure Java implementation of Java ME.
SquirrelJME — Free and open-source
Project developing a full JVM implementation + Java ME 8 APIs. Full compatibility with old J2ME software and high portability are among its main goals. Under heavy development.
J2ME Loader — Free and open-source
This is currently the highest-compatibility J2ME emulator available. Converts .jar files offline using its own resources. Easily launches both 2D & 3D apps. Samsung & Nokia API implemented. Supports different keyboard layouts and customization. It is highly accurate, with the right frame rate for each game, as well as vibration. Has slightly improved performance through hardware acceleration, but games won't run too fast. Runs almost every Nokia game, even ones that don't work with KEmulator or FreeJ2ME, but fails with Sony Ericsson 3D engine (Mascot Capsule), due to the fact that the mascot capsule is almost impossible to port. This is common with most of other emulators as well.
JL-Mod — Free and open-source
This is the experimental mod of the J2ME Loader app with added Mascot Capsule 3D (MC3D V3) support (That means all Fishlabs games like Galaxy on Fire, Deep, etc and Capcom's classics like Devil May Cry 3D and Resident Evil Missions are now playable on Android devices). Has some new and experimental features. Converts .jar files offline using its own resources. Easily launches both 2D & 3D apps. Samsung & Nokia API implemented. Supports different keyboard layouts and customization. It is highly accurate, with the right frame rate for each game, as well as vibration. Has slightly improved performance through hardware acceleration, but games won't run too fast. Runs almost every Nokia game, even ones that don't work with KEmulator or FreeJ2ME, as well as Sony Ericsson 3D engine (Mascot Capsule).
J2ME Runner
Old tool, launches Java Applications on Android using native library. Apps have to be converted first, using Netmite.com. Overall 2D stability is acceptable, but 3D support almost does not work. Different types of keyboard & screen stics are included. Unfortunately, often experiences troubles with *Jar conversion Here and Catalog of games for Java J2ME Runner
This is a Android J2ME Runnner so that any J2ME or MIDP applications can run without modification. Developers can enter the Android Market quickly. You can use your familiar development environment such as J2ME and MIDP or easily port your existing J2ME Application to Android with minimum code change. Users can use java applications directly inside Android
PSPKVM — Free and open-source
Available for cellphones. Might be the first one that's open-source. Last update was in 2011 (0.5.5 Final Edition). PSPKVM is a PSP port of Sun's open-source JavaME implementation phoneME Feature.

This is the reference implementation of J2ME made initially by Sun Microsystems, now owned by Oracle Corporation.

phoneME (unofficial ports)
phoneME for Windows CE/Mobile and Android is an implementation of the phoneME open source J2ME application platform for your Windows Mobile phone or Android handheld device. There are two different platforms of the phoneME Virtual machine : phoneME Feature and phoneME Advanced. Beyond precompiled binaries of these VMs for WinCE and Android based operating systems, this website provides information, patches and instructions in order to compile the phoneME sources yourself.

Symbian and N-Gage (Nokia)[edit]

This page is about emulating Symbian/N-Gage on other systems. For the inverse, see Emulators on Symbian.


N-Gage is a mobile phone and a handheld game system developed by NOKIA, announced on 4 November 2002 and released on 7 October 2003.

N-Gage QD introduced in 2004 as a redesign of the original "N-Gage Classic", fixing widely criticized issues and design problems.

N-Gage was discontinued in February 2006, with Nokia moving its gaming capabilities onto selected Series 60 smartphones.

N-Gage 2.0 was announced in 2007.

Originally a joint Nintendo-Nokia cellphone handheld hybrid project slated for 2005, Nintendo backed away from the project (and its plans for NES/Game Boy ports for mobile were repurposed for their Virtual Engine project). Nokia continued the project on their own anyways and released N-Gage on October 7, 2003, for $299 as the most powerful handheld of its time, that is up until the DS and PSP came along and ended Nokia's hopes at dominating the handheld gaming market. It had an ARM920T CPU at 104 MHz.

However, while gaining support through GBA/PS1 ports (including the only English version of the JP-only Xanadu series until 2016) and a few original exclusives, the thing suffered from huge design flaws, from the button layout to the display and cell phone functionality.

Has a revision called the QD which was unveiled on April 14, 2004, with an ARM9E CPU. ROM dumps of Symbian and N-Gage games are available.

A freeware solution developed by French mobile game developer In-Fusio around 2000. It was a Java-based solution presenting itself as an alternative to the limitations of J2ME's game development (offering missing feautures like sprite zooming, parallax scrolling, rotations...).

It achieved relative success and widespread hardware support in Europe, and was also used in China.

Mediatek Runtime Environment (MRE) / MAUI[edit]

Being the turnkey solutions firm that they are known for, as their chips are used on millions and millions of el-cheapo "Shanzhai" devices all over the world (especially counterfeit Nokias and Goophones among other things), Mediatek has also come up with their own mobile platform and API known as the Mediatek Runtime Environment, aka MAUI. It is targeted for so-called "smart" feature phones, i.e. those that offer similar functionality to standard mobile operating systems like Android, but are watered down for entry-level users. An SDK is available on their developer site for members, and .VXP files for games and other applications appear to be available on the usual WAP sites.

Mophun was an even more hardware-efficient free European-centric mobile gaming solution developed by Swedish company Synergetix. It was supported on various devices, such as the Sony Ericsson T2xx, T3xx and T6xx series, Symbian S60v1, S60v2, S60v3 and UIQ3 phones, and Windows Mobile Smartphones running at a resolution of 176x220 or 240x320. There are 303 known games,[1] of which 255 have been released, 41 are unknown to have been released, 3 are demos and 5 are unreleased. It was later overtaken by advances in J2ME that came with the MIDP 2.0 framework.[2]

Exile is not known to work in any found version of the emulator.
a new, open source emulator by Luca91. It is only a proof of concept, as only a few opcodes and a couple of SDK APIs are emulated, and there is no heap. There is sprite and input support, as well as support for the collision API. It is compatible with a few small homebrews. Luca91 mentions the SDK API handler needs to be better organized.

Japanese cellphones[edit]

Several Japanese-centric mobile game technologies spawned during the 00's as part of convoluted all-in-one technological solutions, mostly based on Java.

  • NTT DoCoMo released DoJa (later renamed to Star), based on Java ME CLDC, but not MIDP. Applications come in the form of .JAR files accompained by a .JAM descriptor.
  • KDDI released ezplus (later renamed to "EZ-appli (Java)"), based on Java ME extended with propietary APIs. Applications come in the form of .KJX files. It was later replaced with a BREW-based solution called "EZ-appli (BREW)"
  • J-PHONE released J-SKY, based on standard J2ME MIDP extended with several propietary 3D/sound/gfx APIs. It was later renamed to "Vodafone Live!" and "Yahoo! Keitai" as the company got purchased by Vodafone and SoftBank, respectively. Applications come in the form of .JAR and .JAD files.

It is possible to develop applications that work both under ezplus, J-SKY and standard J2ME devices by using only MIDP1.0 APIs

i-mode (DoJa)[edit]

Japanese mobile manufacturer NTT DoCoMo released DoJa (DoCoMo's Java) as part of their i-mode set of standards for mobile telephony. It is based on Java ME CLDC, but not MIDP. The profile received several updates, being later renamed to "Star". It was used on DoCoMo's mova and FOMA series of mobile phones, being first featured on the mova 503i from 2001.

While i-mode phones were made available in a limited fashion in Europe, the game apps weren't exported, the i-mode specific features were mainly used for enhancing web pages for mobile browsers and even the Java API is the different more limited "Overseas Edition". The main reason behind this was the fierce push back by Nokia and other western mobile hardware manufacturers refusing to support the DoJa software standard until very late.

DeNa (Mobage), Namco (Tales of Mobile) and Level-5 (RoiD) set up Steam-like game distribution portals specific to some cell-phone models yet i-mode based. The different names are to confuse dirty gaijin, probably.

Applications were denominated "i-αppli" (Japanese : iアプリ) and come in the form of .JAR files accompained by a .JAM descriptor text file.

KDDI ezplus[edit]

Japanese carrier KDDI/Au released ezplus as part of their EZweb set of standards for mobile telephony. It is based on Java ME extended with propietary APIs. The first device supporting it was released on 2001 (Hitachi C451H). ezplus was later renamed to "EZ-appli (Java)" (Japanese : "EZアプリ (Java)") and gradually replaced with a BREW-based solution called "EZ-appli (BREW)" until 2004 when the last ezplus device was released.

In 2006 an Open Application Player (Japanese: オープンアプリプレイヤー) feature was added allowing to run MIDP 2.0 Java apps on the BREW devices, which were often denominated as オープンアプリ. It lacks support for the original propietary extensions of ezplus. On 2011, Open Application Player was updated and renamed to "EZ-appli (J)" along EZ-appli (BREW) which became "EZ-appli (B)"

Applications were denominated "ezplusアプリ" (during the ezplus name era) and come in the form of .KJX files.

Japanese service provider J-PHONE released the J-SKY platform as part of their set of standards for mobile telephony. It was based on J2ME and MIDP extended with several propietary 3D/sound/gfx APIs called JSCL. J-PHONE had been purchased by Vodafone on 2001, which two years later took over the original branding renaming the carrier to Vodafone KK. The J-SKY technology became then known as "Vodafone Live!" and it was extended with the VSCL set of APIs. On 2006, Vodafone KK was purchased by SoftBank Group, getting this technology rebranded again as "Yahoo! Keitai".

Applications were called "Java™ App" (Japanese : Java™アプリ) during the J-SKY era, "V-Appli" (Japanese : Vアプリ) during the Vodafone era and "S! Appli" (Japanese : S!アプリ) during the SoftBank era. They come in the form of .JAR accompained by a .JAD descriptor text file.

Binary Runtime Environment for Wireless (BREW)[edit]

A mobile development platform by Qualcomm, originally intended for CDMA handsets such as those sold by Verizon. Unlike Java ME, applications and games for BREW use native code as opposed to running in a virtual machine in the case of Java ME. Also, BREW development has a higher barrier to entry due to stringent certification requirements, which led it to be significantly less popular than Java ME even in markets where CDMA has a significant market share, such as in North America. To top it all off, downloaded BREW apps are tied to an individual handset via a digital signature, making piracy or sideloading difficult if not impossible; it is however possible to unlock certain BREW-enabled CDMA phones to run backups and pirated apps, though downloads for BREW apps and games are rare and hard to find compared to Java ME.

The Zeebo, a video game console and online distribution platform developed and released with developing markets in mind, also runs on BREW. Dumps of the Zeebo and its games exist, and gameplay footage of them have been uploaded on YouTube.

Danger OS[edit]

Developed by Danger Incorporated, Danger OS was a Java-based OS used on phones that Danger designed themselves. These devices were sold under many names such as Hiptop, Mobiflip, Sharp Jump, and (most notably) T-Mobile Sidekick. While it could run some J2ME apps (from version 2.3 onward), it also used its own proprietary J2SE-based APIs and SDK; for this reason, anything built using these APIs won't run on a standard J2ME emulator.

Dark Age of Monochrome Mobile Phones[edit]

Earlier black & white cellphone games (both in Japan and worldwide) didn't get as much love either when it comes to emulation and preservation of game binaries. There were, however, recreations of Snake and Space Impact for Nokia phones on their website at one time, along with remakes of the aforementioned games for Android and iOS. There are several Nokia phone models with MAME support, though they are preliminary at best with most models displaying a "CONTACT SERVICE" error if not a white screen.

Released in 2000 by Microsoft as their first mobile OS, originally called "Pocket PC" and made to run on PDA's, the name changed to Windows Mobile when the PDA market began to shrink. WM was initially based on Windows CE before evolving into something unique. It was mainly designed for business users, so it didn't have a lot of games for it.
