This is a First Class/SLO/Simplex Elite release. Airheart was cracked by The Talisman and supplied by The Punisher. With thanks to The Box, Ubiquitous Hacker, and The Hitman.
The reason it took so long to get this ware out was because it was 18 sectors a track which is hard to convert and unpack correctly onto a normal dos disk. So what we did was just leave it in 18 sector format. So, the disk will not fast copy and you will need a special packer and unpacker to use the game. Sorry about this, but this was the best way we decided to do it, it saved time, and it is still one side, which would have been very hard to do if we would have changed it to 16 sectors. Also, the load is as fast as the original. So, we figured it would save us time and you time to get probably the best ware of 1986.
