The "Keep Aspect Ratio" option under Win7 is made unusable with nVidia or Intel drivers for LCD monitors including HDCP filters to limit users. This seems to be due to the HDCP crippling of hardware that has the side effect of crippling game aspect ratios. One solution is to use an AMD/ATI video card, which has a work-around: Set video to a resolution less than the display native value. This allows setting up the fixed aspect ratio, which is then retained when native display resolution is restored. Another solution is to dual-boot to Linux (I use Mint 13). Proprietary nVidia drivers under Linux allow the original aspect ratio to be retained. I corrected slightly-choppy sound by raising what appears to be the sound sampling rate in dosboxMOO1.conf (from 22050 to 32050). As for my MOO1 rating, my effort above should show how highly I value getting it to run correctly. I preferred playing it to finishing Skyrim, and may play another game before returning. MOO1 construction and play is a work of art by any standard, which is amazing for a 19-year-old game.
