I would like to know if there is a possibility to change the names of pilots in the mode Clockwork Carnage ... If yes, how to proceed?
Only by modifying executable file (rvgl.exe or revolt.exe).
Any hex editor that can search string (ASCII text) does the job. Will have to figure out how to use it on your own.
The main concern is that you can't add or delete any characters, only replace. So 3 letter name can't become 4 letter name, for example.
