Nintendo DS Startup - Console BIOS/Startup Fanfare is a high quality rip of the Startup sound of the Nintendo DS.
The rip is a remix of YouTuber GradeAUnderA's intro theme in the soundfont of the Nintendo DS startup.
The rip is in the form of an animated video. It includes a visual joke parodying GradeAUnderA's intro. After the Nintendo part of the logo forms, the animated characters GradeA and UnderA take places of the "D" and "S" respectively. The letters then fall down in their respective spots, crushing the two below.
