Cellphone emulators

From Emulation General Wiki
Jump to navigation Jump to search

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, 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.

Java 2 Micro Edition (J2ME)[edit]

J2ME / Java ME
Developer SunOracle
Type Cellphone / Mobile
Generation 6th generation - 8th generation
Release date 2000
Discontinued 2019
This page is about emulating J2ME on other systems. For the inverse, see Emulators on J2ME.
Also see Kahvibreak project.

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 a proprietary 3D graphics engine developed by Hi Corporation. It was mostly used in Japanese cellphone devices, but it also made it overseas featured in many Sony Ericsson devices. Many developers made use of this tech to bring higher quality 3D graphics to the Sony Ericsson versions of their J2ME games.

Currently, the Android-exclusive J2ME Loader is able to run most of the 2D and 3D (including Mascot Capsule 3D) J2ME games. On desktops, KEmulator nnmod should suffice for most games (and FreeJ2ME is also a solid option), 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.

Has more features than others, as well as 3D emulation. It's feature-packed with debugging features, like HTTP proxying. Originally a shareware product, the original author sold it to some other entity (possibly Gameloft) in the late 2000s to be never seen again. KEmulator did, however, receive an unofficial improved version in the form of KEmulator nnmod, which has fixed many bugs of the original (including the infamous Doom II RPG save issue) and added various features. KEmulator nnx64, a port of KEmulator nnmod with some features removed at the cost of being cross-platform, is also provided as of v2.16.
J2ME Loader & JL-Mod (Mascot Capsule 3D compatibility list)
This is also one of the highest compatibility J2ME emulators available. Converts .JAR files offline using its own resources. Easily launches both 2D & 3D apps. 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. Supports various vendor APIs, including its own implementation of Mascot Capsule 3D, alongside some that aren't always seen in other emulators such as a few of the Siemens APIs. JL-Mod is a fork that's updated more frequently, with recent work being done on soundfont support and SoftBank API implementation. Sadly, none of its versions support the Yamaha SMAF (.mmf) music format seen often in Samsung and SoftBank games (KEmulator's implementation is borrowed from Yamaha).
This is a newer project developing a JVM implementation of MIDP. It has shown fast progress over periods of time, and while compatibility is a mixed bag as of this writing (with no 3D support), the feature set is somewhat comparable already to that of KEmulator.
Has fewer features than KEmulator, but can be used for games that don't work with it. It has an optional libretro core, and development is somewhat active with pull requests being accepted and new automatic builds being made. Some games run too fast and require tinkering with the frame rate options. No 3D support.
Project developing a full JVM implementation of MIDP and DoJa + Java ME 8 APIs. Full compatibility with old J2ME software and high portability are among its main goals. Under heavy development. Note that while the standalone builds are capable of running a few games as of this writing (while many others crash at various points or have lag or stability issues), the libretro core is non-functional.
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.

It's a pure Java implementation of Java ME.
J2ME Runner
Old tool, launches J2ME 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 Runner 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. J2ME apps converted found here
Might be the first one that's open-source. Last update was in 2011. PSPKVM is a J2ME emulator for PlayStation Portable, 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 mobile 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[edit]

Developer Nokia
Type Cellphone & Mobile
Generation 6th generation
Release date 7 October 2003
Discontinued 24 February 2006
Successor N-Gage 2.0
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 device developed and designed by Nokia Corporation, 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. Furthermore, as a derivative of business-oriented devices, it didn't even have any dedicated video or sound hardware, so not unlike many of the PC MS-DOS games, the main CPU had to take care of it, severely limiting its full potential.

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.

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.

There however exists an SDK for the Nokia 3410, an enhanced variant of the infamous 3310 with a higher-resolution screen and support for MIDP applications. A fixed rip of the simulator can be downloaded on the Internet Archive, though it may have some issues especially on later Windows versions.

Execution Engine (ExEn)[edit]

ExEn was a freeware solution developed by French company In-Fusio around 2000 and later the company re-developed the ExEn V2 engine in 2002, which further improved the speed and expressiveness of mobile. It was first Java-based game engine entirely dedicated to mobile devices itself as an alternative to the limitations of J2ME's game development (offering missing feautures like sprite zooming, parallax scrolling, rotations).

The API is based on Java and is very similar to J2ME, but is optimized for game development and deployment instead. Even the programming style is almost the same. Its significance is very similar to the Mophun platform. The ExEn API has various gaming specific classes that are absent from J2ME. ExEn was the first mass market downloadable game engine to be made available in Europe. It achieved relative success and widespread hardware support in Europe, and was also used in China. It's not as widely distributed though, and according to In-Fusio's website, it isn't available on Nokia, Sony Ericsson, Samsung or Motorola handsets.

An official emulator, designed for development and demos. As such, encrypted or compressed games do not boot. However, this has been worked around, both by decrypting the files and decompressing them (except for compressed resources), and modifying the emulator to perform decryption on the fly, albeit only when opening them via the Open menu. 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.
Mophun ActiveX Control
The official website for the platform, mophun.com, used to host development demos playable in the browser using the ActiveX platform (crawled demo files here). The mophun plugin itself can run unencrypted .mpn files. Although it is not playable through the web archives of the site, it is expected to be curated for Flashpoint.

Japanese cellphones[edit]

Several Japanese-centric mobile game technologies spawned during the 2000'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 proprietary 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 proprietary 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/Star)[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 proprietary 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 proprietary 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 proprietary 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.

Korean cellphones[edit]

SKT (Sunkyong Telecom) provided two development platforms: GVM and SK-VM. GVM based on Mobile C, and SK-VM based on Java. SK-VM was a Java-based development platform, but the execution speed was slower than GVM due to the nature of Java. SK-VM is a J2ME (Java 2 Micro Eidtion) Java execution environment developed

GVM (General Virtual Machine): GVM1X, GVM2X Mobile platform created based on Mobile C (modified to fit the mobile environment, such as reduction of pointer and union functions in the existing C language) developed by Shinji Soft.

GNEX (General & Next Multimedia Player): GVM3X A mobile platform that eliminates the limitations of the existing GVM and further strengthens functions such as file system, network, and graphics. GNEX is an upgraded version of GVM, and has the advantage of having few capacity restrictions and fast speed, but its penetration has fallen significantly compared to GVM. Therefore, when releasing a GNEX version of a game, we developed both the GVM version and the GNEX version to support phones that do not support GNEX

KTF (Korea Telecom Freete) provided Qualcomm's BREW. The biggest advantage is that it is based on C/C++, and unlike other development platforms, it is executed in the form of a native binary rather than being executed based on a VM. it is an integrated platform, but it has been divided into SKT-WIPI, KT-WIPI, and LGT-WIPI. For example, SKT-WIPI and LGT-WIPI supported C/C++, while KTF-WIPI supported only C. Aside from that, many other aspects differed from carrier to carrier.

LGT (Lucky Goldstar Telecom) - MIDP [JAVA] A mobile platform that adds additional functions such as sound to J2ME (Java 2 Micro Edition) of LG MIDP JAVA SUN. LGT's platform is sometimes called MIDP and JAVA

- LGT's WIPI-JAVA (LGT does not support WIPI-C)

Wireless Internet Platform for Interoperability (WIPI)[edit]

WIPI a national middleware platform standard in South Korea. Almost all cellphone games released in South Korea from 2002 to 2009 were developed as WIPI. SKT (GNEX, SKVM), KTF (BREW), LGT (MIDP-JAVA), etc. are these, and they are currently converting to an integrated platform called WIPI. After conversion to an integrated platform called WIPI, mobile games have higher quality graphics and game ability than before.

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; 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.

Zeebo is a Brazilian and Mexican 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. To aid third-party software design, Danger has released a comprehensive SDK that contains a Hiptop simulator, development installation utilities, and Danger API information.

Danger OS uses special files called "bundles". Bundle files have the extension .bndl. Bundles have inside a custom resource format for storing assets and code which is converted from Java bytecode into a custom bytecode format. Each bundle file is linked to a specific operating system version and build number. For example, a bundle file for v3.4/155053 (T-Mobile Sidekick 3) would be denied installation on a v3.3/149695 device (T-Mobile Sidekick iD). Installation of bundles require a developer key to be installed on your device if you are using a Production OS. Internal OS builds do not require developer keys.

Windows CE[edit]

Windows Mobile (PocketPC)[edit]

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.
