I am not an expert but i think what you have to do to make the mod is this:
1. create a folder called something like multiple starbases v1
2. In this folder create a folder called "GameInfo" (obviously don't put in the quotation marks)
3. Put your modded entity files in this GameInfo folder
4. You now need manifest files. Because you have only changed .entity files I think you only need an entity . manifest so
4.1 Create a text file in the multiple starbases v1 folder
4.2 press "Save as" and call it "entity.manifest" (put in the .manifest don't put in the quotation marks)
4.3 write "TXT" at the top of this file (with no quotation marks)
4.4 write "entityNameCount" (no quotation marks) on a new line under TXT
4.5 For each of the entity files in your gameInfo folder you need an entry in the entity.manifest file that reads like this:
entityName "NAMEOFFILE"
4.6 Count the number of entries in your files and enter the number after the entityNameCount line
EDIT: 4.7 SAVE THE entity.manifest FILE NOW!!!!!!!!!!!!!!!!!!!!!!!!
So if you had modded the four entity files STAR_RED.entity STAR_BLUE.entity STAR_GREEN.entity and STAR_YELLOW.entity
The entity.manifest would read
TXT
entityNameCount 4
entityName "STAR_RED.entity"
entityName "STAR_BLUE.entity"
entityName "STAR_GREEN.entity"
entityName "STAR_YELLOW.entity"
Now put your mod folder (multiple starbases v1) in wherever you normally put mods on your computer
and try it out
good luck
