+notes: |
+  FreeJ2ME is a Java ME (J2ME) emulator for libretro. The native .so/.dll
+  core acts as a bridge that spawns a Java process running freej2me-lr.jar,
+  which handles all actual J2ME emulation. Communication between the C
+  frontend and Java backend happens over pipes (Linux) or named pipes
+  (Windows).
+
+  The jar file is required: without it the core cannot start. It must be
+  placed directly in the system directory (not a subdirectory). The core
+  resolves it via RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY joined with
+  "freej2me-lr.jar" using fill_pathname_join().
+
+  A working Java runtime (JRE/JDK 8+) must be installed on the host
+  system. The core invokes "java -jar freej2me-lr.jar" with resolution,
+  rotation, phone type, FPS, and sound arguments passed via argv.
+
+  freej2me-lr.jar is built from the project source via Apache Ant
+  (build.xml target "lr"). It is not a traditional BIOS dump but a
+  software component distributed with the emulator.
+
+  The project also produces freej2me.jar (standalone AWT frontend) and
+  freej2me-sdl.jar (SDL2 frontend), but only freej2me-lr.jar is needed
+  for the libretro core.
