Robotron has a native 292x240 resolution. I would like to display it at 4x pixel size (1168x960) to keep the pixel count an exact multiple of 4 in both axises to eliminate blur from interpolation.
I can get it to work if I start it inside a window: > mame64 robotron -w -ka -nofilter -resolution 1168x960@60
I would like to run this without a window so I can get an all-black background but keep the 1168x960 pixel count for the game.
When I take off the "-w" (start in a window), I get the all-black background but the game is now stretched for the entire vertical axis introducing blur.
I am using mame v155 command line but have also tried MAMEUI64 and the very old mame32. Can't find a way to do this with any of the versions. Can someone help me out ??
