If your specific phone refuses to run VXP emulators, you have two highly reliable alternative routes to enjoy classic mobile applications: 1. Find Native VXP Ports
Java ME was ubiquitous, but many ultra-low-cost phones used proprietary native runtimes to avoid Java licensing fees or performance overhead. VXP emerged as a lightweight alternative: apps written in C or C++, compiled for ARM7, then packed with a simple header.
JAR games made for 240x320 screens will look distorted or cut off if your VXP phone uses a 128x160 resolution display. Match your game files to your screen specifications.
An IDE like Visual Studio (older versions like 2008/2010 are usually required for compatibility with legacy MRE SDKs).
Ensure the VXP app matches your phone's screen resolution (e.g., ) to prevent display issues. File Size: JAR files larger than convert jar to vxp link
Port your assets (images, audio files) from the JAR archive.
Need to run old Java games on a modern KaiOS or Voxel-powered phone? Here’s the step-by-step guide to converting JAR files to VXP format, including the tools you need and the common pitfalls.
To help you decide on the best path forward, here is a comparison of the available options:
These are specialized executable files designed for the MediaTek (MTK) "Mobile Runtime Environment" (MRE). Many modern, low-cost feature phones (such as older Nokia models, Micromax, and various generic brands) use this platform to run apps. If your specific phone refuses to run VXP
Open the application and select the main class of your Java program.
Instead of converting, most users find it more effective to download the native VXP version of the app.
Converting (Java Archive) files to VXP (MRE/VRE) files is a common request for users of older "feature phones," but it is important to understand that there is no direct online link or automated "one-click" converter that reliably turns a Java app into a VXP app . Why a direct converter doesn't exist
This is a compiled binary format designed specifically for the MRE (Minisite Runtime Environment) platform created by MediaTek. It is commonly found on low-cost feature phones, modern Nokia series devices (like the Nokia 220 or 225), and various Chinese clone phones. JAR games made for 240x320 screens will look
These often have low success rates because the underlying code architecture differs significantly. Using the MRE SDK (For Developers)
Sign or checksum if required:
The only true way to get a Java-like app into VXP format is to have the original source code and recompile it using the MediaTek MRE SDK
We are using a tool called JerryScript or a wrapper that bundles a Java emulator into a VXP shell. You are essentially creating a "host" app that runs the JAR for you.
The server processes the file through an automated wrapper script. Once finished, the site provides a direct download link to the newly generated .vxp file.
