The choice of 320x240 resolution with 256 colors on the VGA adapter is a pretty strange one. I would think that 640x480 with 16 colors would be a much better choice.<p>- For a card game, you don't need much colors (white, black, red, background), but resolution is critical, as there are many fine details.<p>- 16 color mode has a special mode where one byte access can write a color to up to 8 pixels. If you get this trick right, then filling large areas with solid color or simple patterns (such as mostly-white card faces) will be even faster than in 256-color mode.<p>- Subjectively, high-resolution mode with almost square pixels is what makes VGA special compared to EGA. How are you going to brag about you new shiny VGA card if you cannot even show it off? :)
