Jakarta
    Acquires 0xff username bytes
        -> 3ff2
    Acquires 0x1f - uname_len password bytes
        (1f - uname_len) & 0x1ff
        uname_len = 0x20? 0x21?
        => passwd_len = 0x1ff
        -> concatenated to username?
    Return value at 401c
        = [username][password][...]

    before strcpy:
        username -> 2402
        password -> 2402
        concat happens in stack buffer
    Length check happens Byte
        0120 ~= 0x20 <= 0x21
        u_len = (20 or 21)
        p_len = (e0 -> 100)

    Password
    AA [r11] [ret] [fakeret] [args] [AA...AA]

    Lesson: Sometimes things are not the data type you think they are
