I have 'secret files' and Magic Dosbox installed but do not know how to go ahead.
Who can help?

You won't see many on here with rooted device , might be better checking XDA Forums.

You're posting in the Galaxy Tab 10-inch forum, which is for the ancient original Galaxy Tab. Which tablet are you using?
@mustang7757, I'm guessing it's not a rooted device -- the OP wants to play an old MS-DOS game using Magic DOSBox.

As it turns out, looking at the OP's other posts, it does seem like the device is rooted. But I'd guess it doesn't have an impact on the issue of why the MS-DOS games aren't working.
