    There is no GBA unpacker and never will be*, everything is in one rom.

    *While this is the case it is possible to get the GBA binary (as in the machine code) using a fairly simple method (disassemble and set address to 08000000 and the first opcode is a jump to 080000C0 or similar.
    The next few lines are the IO routines and whatnot.
    The next jump to something in the 08XXXXXX range is the location of the proper binary (no more IO routines).

    Pointers on the GBA are 08XXXXXX-09XXXXXX (8xxxxxx is the first 16 megs, 9xxxxxx is the final 16 megs of the rom) or the higher waitstate mirrors and things tend to point to those (or wherever they get decompressed to).

    Other than this methods are the same as every other system out there.
