ranger here is the instructions for making a mod
1 obtain a COPY of the game files in text mode (will use the name Reference files for this in future)
2 create a NEW folder in either Mods-Entrenchment v1.051( or the highest version number you have) OR Mods-diplomacy v1.011
3 create a folder inside the new folder called 'gameinfo'
4 copy the texted planetTYPE.entity files from your Reference files
5 edit EACH of the planetTYPE.entity files in notepad++ or notepad changing the number at the end of the maxStarBaseCountPerPlayer line to the number you want & make any other changes eg range, max levels of upgrade etc saving each file after making the changes
(note if you alter the name of any of the entity files or add any entitys you WILL need to use my manifest maker in my modding utilities pack)
6 start your sins expansion dev.exe and go to options then mods then click on your folder name, then click on enable then click on apply then go to the singleplay and play.
just for your info when helping another modder I had created a planet that could support 8 starbases using this set of instructions.
