Execution Engine (also known as ExEn) was a mobile gaming engine, developed by french company In-Fusio in 4th September 2000. which competed during the early 2000s with Sun Microsystems's mobile Java platform, J2ME. It was the very first Java-based game engine entirely dedicated to mobile devices. ExEn engine wasn't available on Nokia, Sony Ericsson, Samsung or Motorola handsets. The company re-developed the ExEn v2 engine released in April 2002, which further improved the speed and expressiveness of mobile. Through its embedded technologies for non-Java phones (the ExEn game engine) and Java (the EGE game engine which is marketed in 2005), In-Fusio offers players intuitive access to games, games at the cutting edge of novelty (3D, real-time multiplayer) and innovative interactions ('demo' mode before purchase, 'recommend to a friend', contests, game ratings, etc.). The ExEn technology which is fully J2ME MIDP 2.0 game API compliant, has been designed for games containing animated graphics, sound, 3D and color.



ExEn®, a downloading game engine dedicated to play, ultra powerful and light games for your devices. Fifteen full-time engineers worked for two years to develop ExEn, which was launched in France and Germany during summer 2001. At the same time, DoCoMo in Japan and SK in Korea also launched successfully a similar technology. ExEn games are downloaded from the GameZilla platform and are executed on ExEn enabled handsets.

ExEn is a specific 3D Game API. It embedded a very compact Java VM from Shlumberger plus a thin native API to provide maximum performances. This was before J2ME even existed. In-Fusio launched its MIDP 2.0 compliant “ExEn Java Extensions” in end of 2003. Most of the development platforms that we mention here are free unlike the restricted SDKs of console games. ExEn v2 is currently in the works. It will hook up with J2ME's MIDP 2.0 platform and offer further enhancements to games. In-Fusio tried to overcome those limitations working together with Sun by presenting the proposal of a GameAPI for MIDP 2.0.

The In-Fusio SDK is available both as a command line version, as well as GUI.

The In-Fusio SDK is a Java based GUI game development environment on ExEn. They have two kinds of engines on the client side mobile phone, basic and advanced.

ExEn basic (v2.1): 256-color or black and white, 2D, client side game engine, with a memory footprint of 140k on the mobile device. Released in early-2003.

ExEn advanced (v2.2): 65k color, polyphonic sound, 3D, in-game Macromedia Flash, client side engine, with a memory footprint of 240k.

The API is based on Java and is very similar to J2ME specification, but is optimized for game development and deployment instead. Even the programming style is almost the same. The ExEn API has various gaming specific classes that are absent from J2ME.

Some of the game related classes are: Gamelet, Playfield, Raycast, FX, Vector 3D, Texture Map etc. A developer can develop the game using this API and distribute it through In-Fusio directly. But this service is only available to premium members. Since In-Fusio has tie ups with a lot of mobile operators, it acts as a distributor for these games through Gamezilla, its game distribution platform. That enables games downloads on mobile phones by the users themselves.

Raycast Plugin: Mission 3D and Mutant Island 3D

ExEn was the first mass market downloadable game engine (The technology allows users to download games, new levels or characters over the air to play on their cellular phone. The games are then run locally without the need for a continuous connection).

ExEn is a compact game for mobile devices JAVA virtual machine. Once integrated with the terminal, It can download games and play native games. So as long as the built-in ExEn Cellphone with chip, You can start from ExEn The content supplier passes GSM or GPRS Network technology, Download to your mobile phone to play.

Technical requirements: small and light, (less than 100kb of ROM and 32kb of the RAM in its initial version) the software's main function is to download and run games on mobile phones.

By In-Fusio. Aims to be less limited than J2ME. Available under "premium" or "free" SDK licenses.
- Color
- 3D matrix calculations
- 3D rendering primitives (wireframe, flat or textured triangles)
- Sprite zooming
- Sprite flipping / mirroring
- Scrolling parallax (several playfields at the same time)
- Fully transparent or masked cells in playfields
- Raycasting
- Screen rotation (rotozoom) & various FXs

EGE (ExEn Gaming Extensions / Entertainment and Gaming Extensions)[edit]

In 2003, with the emergence of the first smartphones, creating a realtime 3D engine API and native code to embbed into the EGE, the successor of ExEn.

ExEn Gaming Extensions (EGE) was new gaming engine, created to run on all MIDP 2.0 handsets. It is designed for the end-user: improvement of the game play, user-friendly interface and innovative service offering. Enable game developers to focus on game play, rather than API integration (EGE works on Java MIDP 2.0 handsets and integrates multiplayer and 3D capabilities).

- Real-time multiplayer functionality (not available on initial handsets)
- Enhanced/Improved 3D game play (not available on initial handsets)
- 'Recommend the game' function...to a friend, relative...
- Try and buy
- Simplified user interface for easy game play: direct access through a dedicated key (different according to handsets - fast and simple access in particular), dedicated game menu, etc.

ExEn vs J2ME[edit]

ExEn and J2ME are not very different and ExEn paves the way to a Java language based standard.

- The main difference is that ExEn has been optimised for advanced game features.

- Every non-ExEn phone manufacturer has its own specific Gaming API (even on top of MIDP 1.0, the mobile phone profile of J2ME) which induces developers to produce specific code and intensive tests for every manufacturer J2ME implementation.

- The future MIDP 2.0 standard defines a minimum set of game functions to be available in future phones. Even with MIDP 2.0, advanced and rich games are require new Game APIs that ExEn can provide.

- Consistent with its strategy of moving towards J2ME standards, standard classes of ExEn V2 are set in conformity with MIDP/CLDC, which addresses issues such as user interface, persistence storage, networking, and application model.

- The ExEn roadmap - feature new advanced game capabilities and MIDP 2.0 Game API compatibility.
