J2ME emulators: Difference between revisions

'''[[wikipedia:Java Platform, Micro Edition|Java Platform, Micro Edition]]''', '''Java ME''', '''Java 2 Platform, Micro Edition''', or '''J2ME''' is 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 to the Sony Ericsson versions of their J2ME games.

; [[J2ME Loader]] & [[JL-Mod]] <small>([[Mascot Capsule 3D compatibility list]])</small>

: This is one of the highest compatibility J2ME emulators available. Converts <code>.JAR</code> files offline using its own resources. Easily launches both 2D & 3D apps. 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. Supports various vendor APIs, including its own implementation of [[Mascot Capsule 3D]]. '''JL-Mod''' is a fork that's updated more frequently, with recent work being done on soundfont support and SoftBank API implementation.

; [[EKA2L1]]

: According to the documentation, supports a very limited number of J2ME games (specifically those released for Nokia s60v1) by running those on the Series 60 JVM. The firmware has to be obtained separately.

; [[SquirrelJME]]

: Unlike most J2ME emulators, which recreate the J2ME APIs on top of the host system’s Java runtime, SquirrelJME is a project that reimplements the Java Virtual Machine itself (aiming for MIDP, DoJa and Java ME 8, as well as numerous vendor-specific APIs such as JSCL, Nokia UI, WIPI, and more<ref>[https://github.com/SquirrelJME/SquirrelJME/issues?q=is%3Aissue%20state%3Aopen%20label%3Aapi Issues · SquirrelJME/SquirrelJME]</ref>), By taking this approach, SquirrelJME aims to provide deeper emulation with full low-level compatibility, such as accurate memory management and thread behavior, while also enabling portability to environments where no JVM is available. Under heavy development. Note that while the standalone builds are capable of running a few games as of this writing (albeit with various bugs), the libretro core is non-functional.

; [[KEmulator]] / KEmulator nnmod

: Historically has been known for being compatible and versatile compared to others, with certain versions introducing interesting features. Originally a shareware product, the original author sold it to some other entity (possibly Gameloft) in the late 2000s to then quit J2ME development. KEmulator did, however, receive an unofficial modded version (based on a decompilation) in the form of '''KEmulator nnmod''', which has fixed many bugs of the original (including the infamous Doom II RPG save issue) and added various features, such as support for many vendor-specific APIs<ref>[https://github.com/shinovon/KEmulator/blob/main/src/res/res/apis KEmulator/src/res/res/apis at main · shinovon/KEmulator]</ref> and the ability to play SMAF (.mmf) files by copying DLLs from the [https://archive.org/details/sdk-mexa MEXA emulator] (Win32 version only)<ref>[https://github.com/shinovon/KEmulator/blob/main/src/media/emulator/media/mmf/MMFPlayer.java#L18 KEmulator/src/media/emulator/media/mmf/MMFPlayer.java at main · shinovon/KEmulator]</ref>. The latest versions of KEmulator nnmod can boast advanced features for homebrew J2ME app development.

; Nokia SDKs

: A set of different device simulators released by Nokia along with their J2ME SDKs. Keyboard bindings are not friendly for playing games. Some of them are buggy. The Nokia 3410 SDK emulator is capable of running some ancient black & white J2ME games no other emulator can.

; Sony Ericsson SDK

: J2ME implementation released by Sony Ericsson along their J2ME SDK. Includes a [[Mascot Capsule 3D]] implementation, thus usable as a J2ME Loader alternative in that regard, though the keybinds are likewise not friendly for playing games.

; Siemens SDKs

: Device simulators released by Siemens along their J2ME SDKs. Can run some older games that depend on old Siemens APIs.

; Motorola SDKs

: J2ME development kits released by Motorola. Can run some older games that depend on Motorola-specific APIs.

; Motorola iDEN SDK

: J2ME development kit released by Motorola. Can run some older games that depend on iDEN-specific APIs.

; Samsung Java SDK

: J2ME development kit released by Samsung. Can run some older games that depend on Samsung-specific APIs (Yamaha SMAF music may or may not be supported depending on version).

; LG SDK

: J2ME development kit released by LG for their devices.

; Zucotto Wireless Whiteboard SDK

: J2ME development kit released by Zucotto Wireless, provider of hardware-based Java bytecode execution solutions.

; MahoLator

: This is a newer project developing a JVM implementation of Java ME (aiming for MIDP 2.1 and below). It has shown fast progress over periods of time, and while compatibility is a mixed bag as of this writing (with no 3D support), the feature set is somewhat comparable already to that of KEmulator. Sadly, progress on the emulator has come to a halt, though it might eventually come back.

; Pstros

: Appears to have support for some obscure vendor-specific APIs that other emulators don't support.

; SJ Boy

: While it can run a few games not supported by the original KEmulator, it was made obsolete by modern emulators.

; Minisoyo

: 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 <code>.JAR</code> file onto the MiniSoyo window.

; MidpX

: One of the older emulators. Fixed low resolution (176x220) and compatibility, no handler app support. The installer may contain adware.

; MPowerPlayer (MPowerPlayer SDK)
