Here's the thing, I have a lot of old games, even though a lot of them still work on Windows 7, the ones that run at low resolutions and I mean REALLY low resolutions, (were talking 320x200 and 320x240 here) won't play full-screen. Instead, if I try to run them full-screen, it either just simply wont and stays windowed, or it will a black border all around the game. Is there some hack I can do or some (preferably FREE) software I can use to fix this? It's driving me insane having to sit right up close to the screen staring at a tiny image that would easily fit on to a phone screen.

It depends on the game. Many games back in the day where limited to CRT monitors with common resolutions were SVGA 800x600 and XGA 1024×768. And due to the nature of CRT monitors (less pixelation) game developers can run the game even lower resolutions to save on resources.

What games are you trying to play? If it still has a community of players some may of created patches for the new OS or given the game engine the ability to scale with desktop resolutions.

The other option is to run the game on its original OS though a Virtual Machine. You can then stretch the Virtual Machine windows. Emulating an OS and a old game is easy for modern systems today so you shouldn't run into to many problems.
I use to run Command & Conquer on my old copy of Windows 98 though a virtual machine until it became free to download and the modding community went nuts and patched it to run under Windows 7 and up even on 64-bit systems.
