Nintendo Ultra 64 Sound Format
From Free net encyclopedia
Image:64notelogo.png The Nintendo Ultra64 Sound Format (USF) is a file format developed by Adam Gashlin to store sound data (akin to PSF for the Sony PlayStation) ripped directly from a Nintendo 64 video game.
USF files are generated manually from the video game's ROM by isolating the program code responsible for playing music, plus the stored music data. The rest of the bytes of the ROM are zeroed, and the resulting data is stored sparsely (zero bytes are not stored in the USF, so unspecified bytes can be assumed to be zero) but otherwise without compression. The file also contains a Project64 save state which is used to initialize emulation upon loading the USF, rather than follow the complete N64 boot process. The ripping process is very manually intensive because the Nintendo 64 has no standard format in which the music playback code and music data are stored in the ROM. USF files can be played back in Winamp through the use of an appropriate plug-in, such as 64th Note.
The basic USF file structure is a subformat of PSF.
