Windows Mame Resolutions

[marcopolo]

How do you get Windows Mame to display original arcade resolutions like 224x288 for Galaga.  I use the following commmand string:
mamepp galaga - resolution 224x288
and it loads but the image is tiny.  It appears that Windows Mame gave me a 224x288 screen inside a 640x480 monitor.  I want the image to fill the whole screen.  Wierd thing is, if I type the following:
mamepp galaga -resolution 320x240
the picture is huge!!  the image is nice and clear and the game is nice an low res, blocky, just like the original.  But its too big, the screen gets cut off half way down the page.

What the heck am I doing wrong??

Perhaps I'm wrong, but I don't think windows mame can actually reproduce a resolution like Galaga requires because it is so low and exceeds the lower limitations of vga cards.  This is the reason that Andy Warne is developing a video card that has these built in.

I believe that you have to use AdvanceMAME & DOS to create custom video modes for each game, pending the release of Andy's card.
