Can any one help me out on how to set up MS Studio with GCC?
I mean using the project feature etc. ?

There's a small utility that'll create a new type of project under VisualC++.
Check it under www.gbadev.org in the Tools->Misc Section. It's GBA App Wizard.
Of course, in order for this to work, you have to install DevKitAdv. I believe there might be some path to define, for includes, bins, libs.

but I don't think that it's that good, because I don't see any way to use Sin and Cos operations with that Wizard :/
It doesn't also display the code errors in Visual Studio...

To use sin() and cos(), make sure you #include <math.h> and add -lm in your link command line to bring in libm. Because the ARM7TDMI in the GBA does not have a floating-point execution unit, floating-point operations such as sin() and cos() are better done with lookup tables than with libm. You'll get more efficient code, and more efficient code drains the battery less.

There's a patch for GCC that makes it print its error messages in a format that Microsoft Visual Studio understands.

Cool, is there an tutorial wich shows how to use GCC with VS? I already saw some tuts, but they didn't show how to get it work with debug output :(

... but it didn't work :(
This is my batch file I used for compile:
path=C:\devkitadv\bin
gcc -o test.elf tutor1.c dma.c -lm -g
objcopy -O binary test.elf test.bin
pause
and this is the C code:
#include <math.h>
(...)
float TestFlt = 0;
TestFlt = Sin(6.0f);

Use sin() and cos(), not Sin() and Cos(). C is case sensitive.

ok, that solves my problem :o)
What about the debug output?
