I used to love that game back then.
I have tried to play it a few months ago but I had a tiny little problem, the + key didn't want to work, a tad annoying since it's the throttle
The US layout doesn't work for me. So for what is worth and if someone is having the same problem, I have just managed to make it work by switching to keyb uk in DosBox
Now that I can take off at last, bye bye
