Lol, that’s pretty cool. I like geeky stuff like this.?
If you’re looking for a really good keyboard app to use with Dosbox (if you don’t want to use the built-in Magic Dosbox keyboard), you can try Hacker’s Keyboard from Google Play. It’s 100% free, and don’t worry – it doesn’t hack anything. I guess it’s named like that because it features all buttons imaginable from a real pc keyboard.
