u can go into ur computers control panel and click fonts,choose a font u like then replace the fonts in ur skin folder ur using with the ones from the contol panel and rename accordinary ie: vera,vera bd etc
theres usually 4 diff fonts like scoreboard,fm main,vera and vera bd in skin folder, im pretty sure u just need change the vera and vera bd ones for wht ur after
btw: the above is for if ur using a custom skin,if ur using the default game skin then its more technical ie:editing xml files :S
