games install and run fine, but they run in only a portion of my screen, just wondering if there is a way increase the size to use more of the screen, i'm running windows 8

For both games, use the hi-res patches you can find for them on No Mutants Allowed.

Then to iron out all the bugs and issues use the Fixt compilation patch for Fallout 1 and The Restoration Project for Fallout 2 which should also be on there.

Then your games should be set and they should display correctly.

Thanks, still no luck, did some research think its my hardware that is preventing scaling

Maybe it's a problem with DirectX, as Windows 8 comes with version 11 which misses an older library from version 9.
To complete your system, just install DirectX9

Or your video driver is configured not to scale to fullscreen. You can to turn on stretching in your graphics card's control panel.

nVidia
- Go to the nVidia control panel
- Display => Adjust Desktop Size and Position
- Choose the scaling mode to "Aspect ration" or "Fullscreen"

ATi/AMD
- Go to Catalyst Control Center
- Choose the settings page for your display => Attributes
- Enable GPU scaling and set Image Scaling to 'Maintain aspect ratio' or 'Scale image to full panel size'
