Works with vista 64bit, so I imagine it works on everything else.

WIN!

I grew up playing this game, great game.

I remember this.
There also is a remake of Wings of Fury, a similiar game.

There was an old hotseat freeware game called Triplane Turmoil that made Sopwith-style play into a 4-player deathmatch. It kicked ass.

Turns out dosbox runs flawlessly in 64bit vista, much better than dosbox ran in XP. It's interesting, cause I can literally use everything in dosbox whereas before on XP, somethings would work, others were farked.
