What font is used for the in-game battle names?

Also, how do I change some things (logo, text, numbers, etc.) on the victory/match results screen?

EDIT: Well, I did find something called results_en.brres (you can change the look of the numbers and the "WINNER" text, so...HEHEHEHE. But you can't change the character logo and names)
