Currently, [[J2ME Loader]] is able to run most of the J2ME games, also run 3D games with unable to run Mascot Capsule 3D games, The fork of [[J2ME Loader|JL]] is [[JL-Mod]] has run Mascot Capsule 3D 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.

:Experimental emulator from the SJ Boy 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 Windowswindow.

:This is the experimental mod of the [[J2ME Loader ]] app with implemented Mascot Capsule 3D 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).

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

'''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, There are two versions of Mophun, 2D and 3D, for low-end and high-end handsets, and it's often used to provide embedded (pre-installed) games on mobile phone handsets.

It was later overtaken by advances in J2ME that came with the MIDP 2.0 framework.<ref>[https://twitter.com/sczther/status/1345476460107194368 Mophun preservation thread on Twitter]</ref>

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 .jar files for applications, they are uploaded to the device in special files called "bundles". Bundle files have the extension <code>.bndl</code>. 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.
