SquirrelJME

SquirrelJME is a Java ME 8 Virtual Machine for embedded and Internet of Things devices. It has the ultimate goal of being 99.9% compatible with the Java ME standard.

This project is purely written in Java, with a small secondary C project, and is very easy to port to different hardware. For running on native hardware, a compiler handles the conversion of Java byte code to machine code (in an intermediate format). Any system specific APIs are accessed via standardized system calls that handle the logic the compiler cannot provide. An execution engine which is written in C is available and it offers a lightweight method of code execution.

Additionally, there is a port of SquirrelJME to RetroArch which enables the ability to play older J2ME software and games designed for flip-phones.

ALL SOURCE CODE IS WRITTEN BY MYSELF WITH FUNCTIONALITY DETERMINED BY THE DOCUMENTED APIS AND RUN-TIME BEHAVIOR. I HAVE NOT LOOKED AT THE SOURCE CODE FOR OTHER IMPLEMENTATIONS, NEITHER FREE SOFTWARE NOR PROPRIETARY IMPLEMENTATIONS. ESSENTIALLY SQUIRRELJME IS A CLEAN-ROOM IMPLEMENTATION OF THE DESIGN OF JAVA ME 8. THE IMPLEMENTATIONS OF THE JAVA ME 8 APIS AND ASSOCIATED JSRS/JEPS IS CONSIDERED BY MYSELF TO BE IN THE FAIR USE (AND IT ALSO HELPS THE JAVA ECOSYSTEM BY PERMITTING IT TO RUN IN MORE PLACES WHERE IT IS NOT SUPPORTED BY ORACLE).

THIS SOFTWARE IS INCOMPLETE AND IN ITS CURRENT STATE IS NOT CURRENTLY 100% COMPATIBLE WITH JAVA ME 8. THERE ARE CURRENTLY NO STABLE RELEASED VERSIONS OF THIS SOFTWARE. AS SUCH THE FIRST MAJOR VERSION RELEASE WILL BE WHEN IT IS COMPATIBLE SO AS TO NOT VIOLATE POTENTIAL LICENSES, AND IF POSSIBLE BE VERIFIED WITH ANY APPLICABLE TCKS (SO IT WOULD BE AN "OFFICIAL" IMPLEMENTATION).
