1.	Install devkitadv gcc in default directory.

2.	copy fftfloat.cxx to desired directory.

3.	copy following files to
	\header files\*.h to c:\devkitadv\arm-agb-elf\include

4.	create a folder c:\devkitadv\arm-agb-elf\include\myback
	and copy
	\myback\*.h to c:\devkitadv\arm-agb-elf\include\myback

5.	compile the code by first specifying the path
	path=c:\devkitadv\bin
	gcc -o fftfloat.elf fftfloat.cxx -lm
	objcopy -O binary fftfloat.elf fftfloat.bin
	
	then place the code in xport by
	xppro fftfloat.bin -resetmanual

To change the background image
use pcx2gba utility to convert .pcx file into a header file containing 
two arrays.
Refer to function draw_back() in fft_graph.h file to see how bckground 
is drawn.

Reference: www.loirak.com

The bacground images are in back.pcx and back1.pcx which were first 
drawn in paintbrush thus generating .bmp files and later converted
to .pcx file using photo editor.
