Under "AI" open the Teams.txt file. Find the highest-numbered "index __" value, it's 19 in your case if I'm not mistaken, and copy everything from "index 19" downwards. Paste it right below and in the newly pasted text, change the __ value to one number higher, (eg index 19 becomes index 20). You can change the team name and motto by simply rewriting the text. To change the team logo, take your desired picture, resize it to 128x128, give it a ,bmp extension and put it in your AI folder. In the "teams" file rename the line "AI/____.bmp" to correspond with your picture name
Next, copy/paste one of the Team folders, and rename it Team 20 (the same as whatever new index number you created in step 1). Inside are bots called Bot0-Bot5. Bot0 takes the first space, Bot1 the second, etc. Replace those files with your desired bots, and rename your bots Bot0-Bot5.
In the Bindings file add you bots' bindings, being very vigilant of typos.
And you should be good to go
