Hey there. Just wanted to leave this little wisdom for posterity
How to edit any player commentary name and appearance?
Make backup of ur squad file.
Go to game create fake player with what ever appearance, name , commentary you wish.
Save squad
Open RDBM and edit that squad file.
Go to createplayer second from top. Export that table.
Open your backup squad file and paste the new record in it.
At the end change ID to match your desired player ID.
Save. Done.
Delete the squad with fake player and use new squad with imported data.
What you have done is actually make a new record in create player , with desired appearance , name and commentary and with new ID linked it to actual player. Which will inherit that data!
P.S
Export your work "createplayer" table for future use. In case u change your squad file with some newer updated from other people.
Just repeat process if importing create player data into your new squad and enjoy!
