Just to let everyone know today I created an editor to edit the MANA.DAT file containing playernames and teamnames from BMP.
Using my program you can convert the MANA.DAT to an Excel file. You can then edit the Excel file and update all teamnames and playernames. After this you can reconvert the Excel sheet into a MANA.DAT and the updates names will be visible in BMP.
I am am aware of teamed.exe but I was searching for an easier solution to update team and playernames.
