The '''[[wikipedia:Nintendo 3DS|Nintendo 3DS]]''' is an eighth-generation handheld game console by Nintendo, released on March 27, 2011 for {{inflation|USD|249|2011}}. The original model and the 2DS had a dual-core ARM11 MPCore at 268 MHz and a single-core ARM9, 128MB of RAM and 6MB of VRAM, and a DMP PICA200 GPU. The New 3DS and New 2DS XL models upgrade this to an 804 MHz quad-core ARM11 and 256MB of RAM, along with an extra pair of shoulder buttons and a right analogue stick.

'''J2ME Loader''' is a free and open-source [[Cellphone_emulators#J2ME (Java 2 Micro Edition)|Java 2 Micro Edition]] and [[Cellphone_emulators#KDDI ezplus|ezplusアプリ]] emulator <ref group=N> It's not exactly an emulator. It converts MIDlets to Android API and makes J2ME applications to run almost natively in [https://en.m.wikipedia.org/wiki/Dalvik_(software) Dalvik] or [https://en.m.wikipedia.org/wiki/Android_Runtime Android Runtime]</ref>
 +
for [[Emulators on Android|Android]]
 +
It's written in Java. This project is a fork of [https://github.com/NaikSoftware/J2meLoader J2meLoader].
  
The most notable feature of this console is the use of [https://en.wikipedia.org/wiki/Autostereoscopy autostereoscopic] (glasses-free) 3D, which can be configured using a slider. This was omitted on the cost-reduced 2DS and New 2DS XL models, which was released due to eye health concerns with children whom Nintendo advised not to use the 3DS's stereoscopic mode (though it is speculated that said advisories were more for liability reasons in case of a health-related lawsuit).

==Overview==
  
__TOC__
+
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), due to the fact that the Mascot Capsule 3D is almost difficult to port. This is implemented with [[JL-Mod]] emulator.

==Game images==
+
==Compatibility==
===3DS vs. CIA===
 
<!--this section is pretty inaccurate-->
 
There are two big types of 3DS game images currently:
 
;NCSD-type: Includes '''.CCI''' (CTR Cart Image), aka '''.3DS''' - data on physical carts, can be executed right off the bat, not used much since no one bothered to develop a CFW solution to load them yet (besides converting them to CIA) and only overpriced flashcarts (Gateway/Sky3DS) can load them.
 
;NCCH-type: Includes '''.CIA''' (CTR Importable Archive) and '''.CXI''' - installers that unpack game data to the SD card or the 3DS NAND memory. Some homebrew apps (FBI, DevMenu) can install CIA files on 3DS systems with CFW installed. Digital games are often distributed as CIAs.
 
  
*Note that CTR (Citrus) is the internal code names for the 3DS.
+
J2ME Loader is currently capable of playing thousands of J2ME games (Runs almost every Nokia games, especially GameLoft games) with ezplusアプリ games support, more than 96.7% of the J2ME library with supports most 2D games and also 3D with some limitations ([[JL-Mod#Mascot Capsule 3D compatibility list|Mascot Capsule 3D V3]]) games don't work).
  
Due to one format being so far restricted to overpriced flashcarts and the very slow Citra development (meaning playing on a real 3DS is still the preferred way to go), the CIA format is preferred in many sharing websites, downloader tools and even tools to dump your own games.
 
  
However, converting a CIA image to 3DS format (and vice-versa) is still possible with no loss of content. Read the Encryption section below for a guide.
+
<B>[https://github.com/nikita36078/J2ME-Loader/wiki/List-of-Tested-Java-Games-(Touchscreen) List of The Tested Java Games (Touchscreen)]</B>
  
Some outdated dumping utilities intended for use with Citra (like braindump) produce damaged decrypted 3DS images that can't be easily converted back. No known solution exists so far to fix those dumps.
+
<B>[https://github.com/nikita36078/J2ME-Loader/wiki/List-of-Tested-Java-Games-(Non-Touchscreen) List of The Tested Java Games (Non Touchscreen)]</B>
  
===Encryption===
+
<B>[https://github.com/nikita36078/J2ME-Loader/wiki/List-of-Java-Games-with-Bugs List of The Java Games with Bugs]</B>
Most dumps online are also encrypted. This encryption poses no problem for playing game images on a real 3DS since it can deal with that encryption with internal keys included in the bootrom, but becomes a problem when trying to emulate them on PC. '''Citra requires additional encryption keys to play encrypted games.''' If you want to play encrypted games on Citra without these keys, you'll have to convert your game images to the decrypted format.
 
  
Formerly, decrypting those ROMs used to require real 3DS hardware (bafflingly enough, Citra devs still ask users to do this even nowadays). It required files generated by a real 3DS called '''xorpads''' unique to that game version, using the encryption engine within the 3DS. After this part, these xorpads (which are big) can be used with PC tools (or other 3DS-based homebrew) to produce the decrypted game image. After that, some 3DS homebrew (Decrypt9, GodMode9) included tools to directly convert encrypted images to decrypted images with a single button press, but those still require a real 3DS.
+
==See also==
  
The game changer was the sighax exploit, allowing to dump the 3DS bootrom which includes these encryption keys. This file can be downloaded from the [[Emulator Files#Nintendo 3DS|Emulator Files]] page. You can then use a program like '''[https://gbatemp.net/threads/tutorial-extract-decrypt-games-nand-backups-and-sd-contents-with-fuse-3ds.499994/ fuse-3ds]''' to decrypt games using this file. Simply place boot9.bin in the same folder, run the program, mount the encrypted .cia or .3ds, and find the '''decrypted.cxi''' file inside (usually in the first folder). Citra should be able to load this file without issues.

Due to these keys being available, Citra can now play encrypted games (3ds or CIA) without decrypting them. Read this page

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. This project is a fork of J2meLoader.

Overview

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), due to the fact that the Mascot Capsule 3D is almost difficult to port. This is implemented with JL-Mod emulator.

System requirements : Android 4.0 +

Features

  • Fast emulation
  • Highly compatibility
  • KDDI ezplusアプリ .kjx games are support. Only support 128x160 resulation and font option recommend is (9 - 13 - 15)
  • Bluetooth API support
  • Touchscreen input support
  • Supports external virtual keyboards and QWERTY input
  • 3D support
  • Menu key remapping support
  • Supports different keyboard layouts and customization.
  • Individual settings for each application.
  • Highly accurate, with the right frame rate (FPS support) for each game, as well as vibration.
  • Hardware acceleration support (but games won't run too fast).
  • Accelerometer support.
  • Scaling support.
Add support of external shaders filters 

Only shaders for PPSSPP (same 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: ppsspp_shaders
