notes: |
  The native core is a C bridge that spawns a Java process running
  freej2me-lr.jar, which handles all J2ME emulation. Communication
  happens over pipes (Linux) or named pipes (Windows). A Java runtime
  (JRE/JDK 8+) must be installed on the host. The jar is built from
  source via Apache Ant (build.xml). Same repo hosts standalone AWT
  and SDL2 frontends alongside the libretro frontend.
