Why are you using only 16 colors and not just the 320x200x256 mode? It is a lot easier to program just write a byte which represents the color to Mem [$A000:Y*320+x]. Or is the resolution a problem. Then you can always try Xmode [320X400X256] or just try some VESA mode.
But anyway, you want routines for the 640x480x16 mode. What kind of routines are you expecting besides the putpixel and getpixel.
I can provide you those two procedures tomorrow in full 386+ assembler. I guess that you can build other graphic routines based on these two procedures ... if not , just let me know and maybe I write them for you !

Well.. About the use of 640x480 with 16 colors.. It wasn't really my decision because I'm in a club and the main programmer has decide to use it for the project we're working on because we need a high resolution and he only has an old 386 and doesn't have a VESA compatible card... (unfortunately)

I mainly only need getpixel and putpixel procedures...
But a line procedure or a procedure to fill in a closed area might be useful...

I think that should be all.... =)
Thanks for helping... =)

Hello again....

I seem to be having problems getting the OBJ file to work properly..

It compiles perfectly but when I get it to set a pixel it displays 'Rubbish' onto the screen...
