J2ME Loader is a free and open-source Java 2 Micro Edition and ezplusアプリ emulator [N 1] for Android It's written in Java and C. This project is a fork of J2meLoader.

Overview

JL lg.png

Released in 2017, the emulator is currently capable of playing around lot of games. This is currently the highest compatibility J2ME / ezplusアプリ emulator available. Converts .JAR and .KJX 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, but fails with Sony Ericsson 3D engine (Mascot Capsule 3D V3), due to the fact that the Mascot Capsule 3D V3 is almost difficult to port. This is partially implemented with JL-Mod emulator.

System requirements : Android 4.0 +

Features / Settings

  • Fast emulation
  • High compatibility
  • KDDI ezplusアプリ .kjx games are support. Required 128x160 resulation (ezplus has small size games) and font option recommend: (9 - 13 - 15)
  • Bluetooth API support
  • Touchscreen input support (Play touch games)
  • Supports external virtual keyboards and QWERTY input (PC keyboard / GameKeyboard+)
  • 3D support
  • Supported formats .JAR, .JAD and .KJX
  • Menu key remapping support
  • Buttons customisation support
  • Supports different keyboard layouts and customization
  • Individual settings for each application.
  • Highly accurate, with the right frame rate (FPS limit support) for each game, as well as vibration.
  • Hardware acceleration (Graphics mode: OpenGL ES / windows / surface) support (but games won't run too fast)
  • Screen gravity support (Up / Down / Left / Right)
  • Screen orientation (Default / Auto / Portrait / Landscape)
  • Accelerometer support
  • Scaling support
  • Immediate processing mode
Add support of external shaders filters

Only shaders for PPSSPP (.vsh format) are supported to use, you need to put them in the J2ME-Loader/shaders folder in the working folder of the emulator, further in the game settings, select the graphics output mode: HW acceleration (OpenGL ES) and select the shader of interest A small collection of compatible shaders can be taken in this repository: shaders

Font Option (small — midium — large)[N 2]

Here you can set the sizes of small, medium and large fonts that will be used by the MIDlet. Dimensions are in pixels.

If the Scaled Pixel Sizes check box is selected , the specified dimensions will be adjusted by Android to provide the same visible text size on screens with different resolutions. It is recommended to enable this setting when using virtual screen resolutions of more than 240 x 320 pixels.

The Presets button allows you to quickly set the font sizes that are most suitable for a given virtual screen resolution:

Resulation Font
240x320 18 — 22 — 26
176x220 15 — 18 — 22
128x160 13 — 15 — 20
128x128 9 — 13 — 15
Screen Option
  • Width and Height set the size of the virtual screen that will be available to the MIDlet. Many MIDlets are optimized for a specific screen resolution (usually 240 x 320) and may not display correctly at other resolutions.
  • Scale if virtual screen resolution does not match smartphone screen resolution:

enabled - the virtual screen is scaled to fit the smartphone screen off - the virtual screen is located in the center of the smartphone screen without resizing

  • Maintain aspect ratio when scaling:

— enabled - the virtual screen fits into the smartphone screen while maintaining the aspect ratio, possibly occupying only a part of it

— off - the virtual screen is stretched to fill the entire smartphone screen, possibly with distortion of the displayed graphics

  • Screen filtering when scaling improves image quality, but requires more hardware resources

Presets allow you to quickly set the default resolution of the virtual display. The table below shows a list of standard resolutions (for example, HTC Evo 3D, screen resolution 960 x 540)

Resulation Scale Aspect ratio and

screen orientation

128x128 4.21875: 1 1: 1
128x160 3.375: 1 Portrait 3.2: 4
132x176 3.068: 1 Portrait 3: 4
176x220 2.454: 1 Portrait 3.2: 4
240x320 1.6875: 1 Portrait 3: 4
202x270 2: 1 Portrait 3: 4
360x270 2: 1 Landscape 4: 3
405x540 1: 1 Portrait 3: 4
720x540 1: 1 Landscape 4: 3
960x540 1: 1 Landscape 16: 9
  • Options 1 through 5 correspond to standard screen resolutions for mobile phones. They provide the greatest compatibility (most MIDlets are optimized for one of these resolutions), but when scaling to the smartphone screen, the graphics quality may decrease slightly.
  • Choices 8, 9, and 10 provide the best graphics quality because they are calculated based on the smartphone screen resolution and do not use scaling. However, if the MIDlet is not optimized for these resolutions, it may not work correctly or not work at all. In this case, it is recommended to select a lower resolution.
  • Options 5 and 6 are intermediate in quality and compatibility. They are calculated based on the resolution of the smartphone screen so that there are exactly four physical pixels for each virtual pixel. This removes distortion when scaling. When using these options, it is recommended that you turn off screen filtering to sharpen the picture.

The Background button allows you to select the background color of the screen. This color will fill the stripes at the edges of the screen if it is not completely occupied by the virtual screen.

Known issue with workrounds

Mascot Capsule 3D V3 games doesn't works.

★ Mascot Capsule 3D V3 is only few way to emulated :

1. Sony Ericsson SDK/JDK for Windows, it doesn't work on X64.

2. JL-Mod - Mascot Capsule 3D V3 partially implemented on JL-Mod but you can play almost every game, few games doesn't work properly or slow speed.

3. KEmulator for windows, regular version 0.9.3 doesn't supported but 1.0.3 modded version + Mascot Capsule 3D support here

Tips
  • Enabling filtering in some cases can greatly reduce performance. Disable this option if game is too slow.
  • Image flickering issues can be fixed by enabling the Immediate processing mode option.
