The official MRE SDK was a Windows-only IDE. Fortunately, modern developer tooling has provided an alternative. A significant advancement is the creation of , such as the mre-makefile project on GitHub. This project provides a Makefile-based build system, allowing you to compile VXP files under Linux or Windows without the proprietary IDE.
I know this might not be the answer you were hoping for. The quest for a magic "convert jar to vxp new" tool is one many have embarked on, only to find the same reality. The bottom line is:

The most famous tool historically was JarToVXP.exe , part of a hobbyist SDK. It worked by embedding the JAR inside a BREW shell that included a minimal Java VM. Unfortunately, the original tool is 32-bit and expects Java 1.3. convert jar to vxp new
Look for dedicated MRE SDK compilation tools or online automated converters. (Note: Always scan downloaded conversion software for malware, as many legacy modding tools reside on unverified community forums).

Are you encountering any during your conversion attempts? The official MRE SDK was a Windows-only IDE
No, there is no automated, direct converter that can take any arbitrary JAR file and output a functional VXP file.
. JAR files use a Java virtual machine, while VXP files are native binaries built for MediaTek’s platform, often written in C/C++. Recommended Conversion Methods
If converting JAR to VXP proves impossible for your complex app, consider these alternatives: The bottom line is: 00000000: 56 58 50
