J2ME Loader is free and an 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
Released in 2017, the emulator is currently capable of playing around thousands 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 implemented with JL-Mod emulator.
★ System requirements : Android 4.0 +

- → Add support of external shaders filters
Only PPSSPP (.vsh format) shaders are supported, to put them in the JL-Mod/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 Here
- → Game setting
– Enable display of screenshot button, side menu
A. Set the resolution of the loaded game. Select in the game settings and also specify any resolution, specify any for 3D and touch games, since they often have auto-scale, supports 4k.
A. Choosing a background color under the main game.
Q. Scale
A. Image scale from the specified resolution.
A. Changes screen orientation: Landscape, Portrait, Auto
Q. Filter
A. This function increases the quality of the game, but may also decrease the performance.
Q. Graphic mode
A. Selecting the render
mode The graphics mode only affects the final scaling of the frame and the way it is delivered to the screen
1. Software - Used by CPU to output 2D and 3D graphics
2. Hardware OpenGL ES - The mode uses OpenGL ES 2.0 directly - this can be more profitable if the device does not supports newer versions
3. Hardware window - Outputs a frame in a way that is used for buttons, lists, progress bars and other UI
4. Hardware Surface - Available since Android 6.0+ uses the interface that is usually used for video output
Q. Shaders
A. Shaders are GPU microprograms that affect the game in one way or another in order to improve it or replicate the visual features of some on-screen devices, such as displays on portable consoles or old tube TVs. Shaders can significantly alter the game, but also reduce performance. In addition, shaders can have customizable parameters, if there are such an icon for accessing them will be displayed on the far right side and opposite the name of the selected shader.
Q. FPS limit
A. When game running fast, it allows you to reduce fps for a comfortable game, for example: Rayman 3 128x128.
A. Used in games with touch controls, Ex. 640x360 / 800x480 resulation games.
You can also disable the button overlay, as they are not needed
Q. Save / Load state supported?
A. No, because It's impossible, JL-Mod doesn't emulate hardware, so it can't save the CPU/RAM state.
- → 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 Games. 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 240x320 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 games. Many Games are optimized for a specific screen resolution (usually 240x320) 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 960x540)
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.

Japanese carrier KDDI/Au released ezplus as part of their EZweb set of standards for mobile telephony. It is based on Java ME extended with propietary APIs. The first device supporting it was released on 2001 (Hitachi C451H).
Applications were denominated "ezplusアプリ" (during the ezplus name era) and come in the form of .KJX
files.
