Because the best old Stars! websites keep quietly disappearing all of the utilities below have download links from Stars!wiki itself, if you are the author of any of these files and would like a file to not be available from Stars!wiki, please contact Gible to have it removed. Where possible, links to files' homepages or original web locations are included. - feel free to add any we missed. Icon smile.gif

You can also help by writing the individual articles for the utilities that require installation or usage instructions, or just coz they deserve it. Icon smile.gif

Stars Player Colours Changer

download StarsPlayerColoursChanger.exe 35.5kb

"Player Colours editor that edits the English (or what Americans call English anyway) version of stars 2.6jrc4 that is 3,344,384 bytes long." Purely cosmetic.

Colour Map which shows a set of colours on the Space, Scanner & Pen Scanner Coloured backgrounds, the default set creates the page using value of 0,64,128,192 & 255 for each of the components which produces 125 colour combinations but it can also be set to use a different list in the parameters such as link which create 216 based on 0,51,102,153,204 & 255 (00,33,66,99,CC,FF) For helping to find suitable colour values to use.

Game setup utilities


A spiral galaxy creator for Stars!


Map2XY will take a .xy file and a .map file and modify the .xy file to match the .map file. This allows moving planets on the y axis (north/south) quite a bit, since you cannot change the order of the planets, the x axis isn't too modifiable, except you could stretch or compress the universe. It also allows renaming the planets, to other Stars! names only.


Mapper recreates the xy universe file from a GIF file. Also allows the xy file to be exported to a GIF.

Star Name Changer

Allows you to change the names of your stars/planets in Stars! games. This only affects your XY file, so if you want the changes to apply to everyone, they will need to receive the updated XY file. Zip file contains instructions, and different versions for different operating systems.

Stars Host Editor

Stars Host Editor is an ActiveX object model for editing planets in the *.hst files via vbs scripts(or other means). Currently sufficient properties are editable for dramatic changes and PaulCr plans to keep going until everything is editable. See also #Stars Player Editor

Stars Planet Swapper

Preliminary utility for swapping planets around, open turn file and get the id for the 2 planets you want to swap, subtract one and enter them into the utility. The planets and any ships in orbit will be swapped after a gen takes place, there shouldn't be a .x file when generating since it will not be corrected for the changes. A couple of limitations noted by XyliGUN "which looks more like a bugs, but not a real limitations:"

  1. You cannot use it with remapped universes (but you can remap them after swapping), otherwise fleets will be located somewhere in space.
  2. If players' secondary planet (IT, PP) has lower id than HW then after swapping it should keep id that will be lower than HW. And if it was higher it should be keept higher. Otherwise that player will see his HW or secondary planet uninhabited until first gen.

Battle Movement Studies

The XLS spreadsheet results of AlexTheGreat's study on which ship moves first when they are of similar weights.

"I don't know that I'd call it a study. I just determine the correct formula, determined whether the Help file (15%) or FAQ (20%) was right by running some tests & made a simple S/S.
One thing that I have been meaning to do is check whether BS has an effect. eg. Ship A has BS=2.25 & Ship B has BS=1.75. In battle round 1 Ship A is capable of moving 3 spaces but Ship B is only capable of moving 2 spaces. I suspect that it makes no difference, i.e. that Ship A always moves 2 spaces & Ship B always moves one space & only then that the odds are calculated for their final possible movement. However I have not gotten around to confirming that suspicion."

Denham's spreadsheet and graph support the results of AlexTheGreat. It includes results from 1072 battle simulation last moves with ships of two different speeds.

Unlike Craebild HabCalc, this calculates based on the complete set of possible planet values rather than a random sample or a theoretical distribution. To use: edit input.txt, run habcalc and the results will be stored in output.txt.

ForceUser's ISAR Calculator

"Inner Strength and AR Population calculator. (It's a dos program but should work fine in Windows) I wrote it using Turbo Pascal in Grd 11.
