[What's New 1.0.2]
* New core! The core is a modified version of VBA-M and VBA 1.80 beta 3
* Better emulation speeds. Should now be nearly full speed all the time
* Turbo speed feature. Mapped to right C-stick (classic controller &
Gamecube controller), and A+B for wiimote
* Controller mapping preferences bug fixed. Your preferences will reset
automatically to correct any problems in your preferences file
* Fix a frameskipping bug
* Some tweaks behind the scenes
[What's New 1.0.1]
* GBA games now run at full speed
* Menu improvements, with spiffy new background - thanks brakken!

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

zero.
The field `has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field `flag' is not NULL, it points to a variable that is set
to the value given in the field `val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an `int' to
a compiled-in constant, such as set a value from `optarg', set the
option's `flag' field to zero and its `val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero `flag' field, `getopt'
returns the contents of the `val' field. */
