@sha0coder

USAGE:
    mwemu [FLAGS] [OPTIONS]

FLAGS:
    -6, --64bits         enable 64bits architecture emulation
        --banzai         skip unimplemented instructions, and keep up emulating what can be emulated
        --flags          trace the flags hex value in every instruction.
    -F, --fpu            trace the fpu states.
    -h, --handle         handle Ctrl+C to spawn console
        --help           Prints help information
    -l, --loops          show loop interations, it is slow.
    -m, --memory         trace all the memory accesses read and write.
    -n, --nocolors       print without colors for redirectin to a file >out
    -r, --regs           print the register values in every step.
    -p, --stack_trace    trace stack on push/pop
    -t, --test           test mode
        --version        Prints version information
    -v, --verbose        -vv for view the assembly, -v only messages, without verbose only see the api calls and goes
                         faster

OPTIONS:
    -A, --args <ARGS>                  provide arguments to the EXE like: --args '"aa" "bb"'

    -c, --console <NUMBER>             select in which moment will spawn the console to inspect.
    -C, --console_addr <ADDRESS>       spawn console on first eip = address
    -d, --dump <FILE>                  load from dump.
    -a, --entry <ADDRESS>              entry point of the shellcode, by default starts from the beginning.
    -e, --exit <POSITION>              exit position of the shellcode
