I'm aware that this question is posted a lot and I've looked at forums and tried what people are sayimg bit I am at my witts end. I just cannot get it to go full screen. My graphics card is a AMD Radeon (TM) R9 380 Series. If anyone could help that would be greatly appriecated as I loved playing MM6 and want to play through it again.

What is it currently doing? Running in a window? I run Windows 10 with an AMD card and as far as I know it's always run in fullscreen. Maybe try making a shortcut for the .exe, then right clicking that and toggling the "Run" option under the Shortcut tab? Sorry I can't be more help.

If you mean seeing black bars at the side, that's because it's an old game and was created in a 4:3 ratio (back then, that's what most CRT monitors used), with no option of changing it to widescreen.

If you do remove those black bars, it will be stretched out of propotion.

However, if you really want it done, it's possible. Go to your AMD control panel, and look for a Scaling option or similar. Unselect "Maintain Aspect Ratio" and choose "Full screen" or similar instead.

(Alternatively, if you mean that the game appears as a small window in the center surrouned by black bars on top, bottom and sides, then go to Scaling, and instead of Center, select Maintain Aspect Ratio).
