Hi, greetings, im doing some custom dosbox build for my personal use in my 1280x800 screen laptop, i want pixel perfect scaling, and decide for 4x4 for 320x200, 2x4 for 640x200, 2x2 for 640x350 and 640x400, etc

I have a question for my hercules build, hercules is 720x348, any ideas if is possible to center the image horizontal? i check the code, but did not find any way

Same happen with 640x480, that 800 is not enought for 2x480, i will love to center in this case, vertically

thanks for any help
