|
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.
