How to change font main mu?

Usually the first line of text.bmd represents the name of the font to be used by the main, usually "Tahoma", but also has editing via dll, if the minimum concepts of programming will know how faser

Sorry for bad english

1st Open text.bmd with a bmd editor (I used PentiumTools)
2 The first line of the file is the name of the font in the main will read.
3 Edit and save!
