In order to display more than 16 colors with BC++, you must use a SuperVGA BGI. BC++ 4.5 includes the "SVGA256.bgi" file;and I think that's what you need.

I think there isno need to make your program run with a simple VGA. Nowadays, almost everybody have a SVGA video card, so if you use this bgi, it will work in almost every computer.

You must remember one thing: You can set your own rgb palette, with your own colors; apart from the standar BGI's colors. Thisi is: you can send to the video card the palette you want (a 16 colors palette, a 256 colors palette, or a palette you have just read from a .gif file) using the 'outp()' function to the video port.

If you want I can send you an example in C of one of my programs.

I hope this will help
