PowerUP decoding engine for PowerUP version 2.18
------------------------------------------------
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.

The PowerUP ELF file is called "Internal" and has to be placed in the
"Engines" subdirectory of AmigaAMP.

In the AmigaAMP config tool this new engine will show up on the system
tab as "PowerUP" which you have to select. Autodetect might also work
but once you know which engine you want to run it's better to select it
directly.

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.
