Technical notes

Java ME 8 virtual machine. Runs J2ME MIDlets and older flip-phone games. Requires a class library JAR in the system directory. The core searches sjme_nvm_romNames[] in priority order and uses the first match found. All entries are optional: without a class library, the core runs a built-in modeless stars demo but cannot execute J2ME software. The .info declares firmware_count=8 but the code defines 10 search names (squirreljme-{version}-test.jar and squirreljme-test.jar are missing from .info).
