Why does the HUD or menu text look blocky?
Project64 attempts to faithfully emulate the N64 as much as possible – on the N64 games can control exactly when and what type of filtering is used, and text and HUD icons etc are often not filtered because they’re designed for a TV screen, where filtering would actually make them look worse. If you wish, there is an option to force filtering in the video plugin options – on your high resolution PC monitor this can often make things look better, however it may also cause problems with the legibility of text in some games, as characters may acquire a sort of halo around them – if you see this problem stop forcing filtering (see below).
