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 on the Sony Ericsson version of their J2ME games.
Emulators
Currently, the Android-exclusive J2ME Loader is able to run most of the 2D and 3D (with Mascot Capsule 3D exclusive) J2ME games. On desktops 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.
