Ok so I have a buddy who said that playing older games in windowed mode will help them look much better graphically, since the image isnt streched out then. But the window I get when I ALT + Enter is pretty small, is there a way to resize it? I dont see an option to in the game options menu.

Errr .... that's one big kettle of fish you have there.

First of all, not all games support a window - do you mean games running in DOSBox or old Windows games? The former has all sorts of settings to increase the window size, but the latter usually doesn't even HAVE a windowed mode and if they do, it's a rare thing for there to be an option to resize it beyond changing resolution.

Yea thats what I meant in DOSBox, my bad for not writting that. How can I go into DOSBox and resize the windows in games?

There's an option somewhere to draw everything at 2x or 3x scale... I usually run fullscreen though, so not sure where the option is...

You should take a look at this:

http://www.dosbox.com/wiki/Dosbox.conf#scaler_.3D_none_.7C_normal2x_.7C_normal3x_.7C_tv2x_.7C_tv3x_.7C_rgb2x_.7C_rgb3x_.7C_scan2x_.7C_scan3x_.7C_advmame2x_.7C_advmame3x_.7C_advinterp2x_.7C_advinterp3x_.7C_2xsai_.7C_super2xsai_.7C_supereagle_.7C_hq2x_.7C_hq3x

you do this in dosbox conf file for each game. Pretty much everything is described in this article.

Just seconding what keeveek said, it might seem daunting at first but it's actually pretty simple.

The bits to look at would be:

Output: The default is surface and it doesn't support scaling. I usually use ddraw but you can use whatever you prefer.

Aspect: This makes games that used 320x200 with nonsquare pixels look the right shape by scaling them up to 320x240. You almost always want this on true.

Scaler: This multiplies the resolution by whatever. For example for a game that is 320x240, normal2x makes it 640x480, normal3x makes it 960x720.

Finally, you want to scroll back up to Windowresolution. This is the final stage of scaling to use if you want the picture bigger than 960x720. If you used this from the start without the multipliers then it'd be very blurry and you'd be back where you started, but hopefully the scalers will help preserve some clarity.
While you're in this section, it might be worth changing Fullresolution to the native resolution you use for your desktop.

Thanks for making that post. You described in simple words what I couldn't. I wish gog would make a sticky topic with DOSBox hints and tips for configuring the game.

I mean, default configs are mostly good, but making it easier for people to make some enhancements on their own would be great, too.
