:''This page is about emulating J2ME on other systems. For the inverse, see [[Emulators on J2ME]].''

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.

: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.

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 <abbr title="$377.10 in 2018 money">$299</abbr> 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.

: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.

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 <b>DoJa</b> (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.

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

Japanese mobile manufacturer NTT DoCoMo released [https://en.wikipedia.org/wiki/DoJa 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.

===J-SKY===

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".

'''GVM (General Virtual Machine)''': GVM1X, GVM2X

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

===KaiOS===

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.

Danger OS uses special files called "bundles". Bundle files have the extension <code>.bndl</code>. 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.
