This Wii homebrew executes ARM code on the Starlet with Palapeli's exploit, and uses it to set the Starlet in Jazelle mode. It then jumps to the JVM bytecode specified in bytecode/bytecode. In the included example, it is:
bipush 19
istore_0
iload_0
ireturn
After the execution, it prints the state of the stack, and the 8 first local variables.
NOTE: A large number of instructions is not natively supported by Jazelle and must be handled by predefined ARM code. As except ireturn none has been implemented here, it will fail to run most programs. Placeholders for the handlers are available in src/arm/instr_handlers.s. This repository can then serve as a basis for a broader implementation.
