MAME - Setting native resolution question.

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 ??
Thanks

Set prescale to 2 and filter to 0

This did not work, it stretched the screen to the full vertical length.
I tried several combinations:
> mame64 robotron -prescale 2 -nofilter
> mame64 robotron -prescale 2 -nofilter -ka
> mame64 robotron -prescale 2 -nofilter -resolution 1168x960@60
> mame64 robotron -prescale 2 -nofilter -ka -resolution 1168x960@60

you need integer scalling for what are you trying to do
official mame support this only in ddraw mode
in d3d mode (the default) you will need to use a variant of mame build which has cleanstretch option or compile official mame with cleanstretch patch applied

I loaded openEmu on a Mac Powerbook from work just to see what it looks like
(I use Windows7 at home) and I see an option called: "Zoom Level: Integral"
Is this the option you are talking about?
Also, does anyone know of a pre-compiled Windows version of MAME with cleanStretch
or IntegralScaling? (or whatever it's called  )
Thanks for all the info so far..

CabMAME and GroovyMAME both have integer scaling.

note: you would have to settle for older versions. cabmame is no longer updated (possibly the cabmame code is no longer compatible with recent mame versions), and i dont know if mameuifx had cleanstretch in the past, but it doesnt have it today (note: the recent cleanstretch feature found in mameuifx has been renamed to widestretch to avoid confusion, because i think that feature is actually to allow widescreen lcd users to avoid black borders on the sides, so not related to the cabmame cleanstretch feature

using SailorHat patch i modified it so you can input how much scale do you want
example
mame robotron -xxxx 3 -yyyy 3 -noflt
this will give you x res *3 and y res*3 in integer
all credits to SailorHat i just added two variables
i included mame 32 bit(i dont have a 64 machine)
in emus.zip in 3 three files modified, maybe someone could make a diff file
mamesource used was latest 155
