OpenXDK

Here's a cool project...OpenXDK

I was successful in getting the sample to compile and run on the XBOX:

#include 

#include 

#include 



void WinMainCRTStartup()

{

    char  buffer[1024];

    float last = (float)KeTickCount;

    int   fps  = 0;



    RtlZeroMemory(buffer, 1024);



    // Currently, this is the only mode supported by xhal.lib

    InitMode( MODE_320x240x32 );



    // Animate up and down

    int y=25, ys=1;



    // XBox software does not typically ever return from its entry point

    while(true)

    {

        

        WaitVBlank();		// Wait for Vertical Blank

        Flip();		// Flip

        Cls();		// Clear screen



        fps  = (int)(1.0f/(((float)KeTickCount - last) / 1000.0f));

        last = (float)KeTickCount;

        

        // Print to screen

        sprintf(buffer,"OpenXDK Sample: %d fps", fps);

        Print(50,y, buffer);



        // Move text up and down

        y+=ys;

        if(y > 175 || y < 25)

            ys = -ys;

    }

}

This piece of code remindes me of the code we use to write for MODE 13 on the PC (320x200x256). Clear the buffer...write next frame...wait for vertical retrace....flip buffer to screen...cool stuff!

Looking through the library one could see it's still a bit limited however there's great potential!
