Found a simple loophole for team editing:
Go to C:\Program Files\Steam\steamapps\common\cricket revolution\system\data\game\0
Pick the team you want to edit, for example Australia is 0 (I'll write up a list of each team's number soon). Go into its folder and copy the Default-.tm file to
C:\Program Files\Steam\steamapps\common\cricket revolution\system\data\game\0\15 which is Canada. Start up the game, go to team management, click other playing nations in the corner and pick Canada. Make your changes to the team, alt tab out and copy the Custom-.tm from ...game\0\15 to ...game\0\0 overwriting the existing file.
Then to check everything is right, go into the edit team mode with Australia and check all the names are right. Leave the 'default-.tm' files as the originals, I think online play will use these and the game stuffs up if you edit them.
BACK UP THE C:\Program Files\Steam\steamapps\common\cricket revolution\system\data\game\ FOLDER FIRST!
