Random star system generator program STAR.EXE, used to be mzstar or mektonzeta star .

I found this one many years ago and have been unable to find a site where it can be downloaded so I put it, unatributed, on my wetpaint site for you to check out. Run the exe and it creates a text file output with the star system.

Sorry for got to include sample output....

doesn't work on Windows 7

If changing the compatibility settings in win7 won't allow it to work then there is not much we can do, its an old program.

The problem seems to be with 64bit versions of Windows. Doesn't work with my Vista64 either, compatibility settings don't help.

Thats a bummer. It is so dead easy and fast to use.

Works beautifully on Windows XP.

Thanks a bunch! I just love random generators like this!
