how do I get full screen in mame?

[danny_galaga]

Sounds noobi-ish. Ive been using mame (v78) for years, mostly on win98, without any probs. But now I've fixed up my cab with a new 'puter, and XP. I can't seem to get the games running a full screen. There's a huge black border around it. Particularly vertically. Previously, when it was on tinyxp, i found a workaround by inventing the 'danny' aspect ratio of 6:5. I'm sure I did a couple of other things too, but I can't recall.

Anyway, with a new install of real XP, and new install of mame, I cant seem to change the aspect ratio. See attached. What's going on? What should I be looking for so that I can have a full screen of MAME goodness? Don't get hung up on the aspect ratio thing either, that was a desperate workaround. All I want is a full screen (",)

I know older versions of command line Mame have an argument called -hws (hardware stretch) that fits the game to my desktop LCD screen.
Im not sure about that version you are using, maybe look for hardware stretch in the options?

Just had a look for it, and realised that also is greyed out in the screenshot. Why are the two things I want to change greyed out? This is some sorta Murphys law

I must be getting sleepy, I didnt even see that option first time. I dont have any idea why it is greyed out.
Have you tried running a game in command line with the -hws argument?

I actually wouldn't know how! I use mame32. But I'm guessing the hws thing would be in a file. I looked in the mame32.ini file. I highlighted the bit I think is the equivalent of what you are talking about. Is there anything in this list that looks like I should change?:

[Gray_Area]

That feature is grayed out when my video drivers aren't yet installed. Or the chipset (if integrated) isn't advanced enough to handle it....though any P4, with I think at least 32mb or video memory, will.

Trust someone with the moniker of 'Gray area' to know what the greyed out areas mean 

That was the answer. I just found the the disk for the motherboard and installed the drivers. All good now. Thanks guys (",)

Danny_Galaga, how do you feel about the appearance with HWS enabled?  I have the same issue with vertical games on a 4:5 LCD rotated.    I have been satisfied for a while with the approx 1/2" black bars alongside the vertical picture, maybe I'll keep it that way.  I need to experiment and see what happens.

Good times.

Hwstretch I think was created/developed because people wanted to easily have the display area filled, and hardware was becoming capable of doing this via software scaling. The current implentation of D3D in MAME automatically does this.
