While in university a friend and I dumped the original sky roads levels by dumping the dosbox heap while the game was loaded and reverse engineering the memory map. If i remember correctly we emailed the original devs (who are awesome) and they gave permission for rerelease for the open source remake available at the time.
A bit of gaming history: this is apparently a clone of a game called SkyRoads which Wikipedia claims to be a clone of "Kosmonauts", but that is obviously a clone of a hypnotic space-themed game Trailblazer from the 80's. See here <a href="https://www.youtube.com/watch?v=5EXsxd8O7eU" rel="nofollow">https://www.youtube.com/watch?v=5EXsxd8O7eU</a> for C64. Thus, the question arises: does anyone know if Trailblazer itself is a clone of some other game?
I think this would make for a great mobile game - not sure if the devs have considered supporting mobile platforms for it, but I can't seem to find anything approaching a good clone on the play store.
