External decoding engine for 68k version 2.24
---------------------------------------------
AmigaAMP comes with built in support for mpega.library to allow playback
of MP3 files even on slower 68k based Amigas.

However, there's an alternative. It's called the "AmigaAMP decoding
engine". It's more accurate than mpega.library and it has some extra
features as well. Unfortunately it's too demanding for an original
classic Amiga and its 50 MHz 68060 processor, so this engine is usually
only available for PowerPC.

But there's hope. If you are running AmigaOS on an emulator like
AmigaForever / WinUAE or Amithlon on a fast PC you can copy this file
into AmigaAMP/Engines replacing the the one that's currently in there.

In the AmigaAMP config tool this new engine will show up on the system
tab as "68k-Emu" which you have to select. Please don't use autodetect
as this will not work.

The advantage of this engine over the built in mpega.library support
is that the equalizer acutally works and the visualisation is more
accurate as well. Also it's using floating point operations which gives
higher audio quality than integer math.

History
-------
v2.24 - Fixed race condition during preloading/seeking.

v2.20 - Skipping possibly corrupt frames at beginning of file
        when trying to determine bitrate.

v2.19 - Fixed possibly uninitialised pointer causing crashes and/or
        corrupted memory
      - Better detection of average bitrate for files that don't have
        a XING header
