Cellphone emulators

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, KDDI ezWeb, SoftBank...). Some of these games got ported to the inferior Western hardware but these are in the tiny minority.

Nokia

Monochrome mobile phones (S30/S40)

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.

In-Fusio

Execution Engine (ExEn)

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.

4Mophun

Does not work with games that are locked (e.g. have a predefined IMEI recognition algorithm) or do not use the 3D engine.

mophun

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.

MoRePhun

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

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)

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, with various games for DoJa "Overseas Edition" seeing release, the services didn't prove popular enough and were shut down in a matter of years. The main reason for the limited support 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.

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

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.

J-SKY

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

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.

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.

Qualcomm

Binary Runtime Environment for Wireless (BREW)

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

Danger OS

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.

TTPcom

Wireless Games Engine (WGE)

WGE (Wireless Game Engine) was a proprietary mobile gaming engine developed by TTP Communications Ltd. (TTPCom) around 2001 and discontinued in 2003. Unlike J2ME, WGE executed native C/C++ binary code without a virtual machine, allowing much faster performance and lower memory usage on early mobile phones.

The engine supported high-quality 2D graphics, basic 3D, sound, networking, and multiplayer, and enabled secure OTA downloads with DRM. Its WGI API exposed device features through modular components such as graphics, sound, input, and networking, and could be accessed via C++ or Java.
