Double Dribble is an early basketball game for the NES, infamous for the bad quality of its voice sample at the title screen. Fans have interpreted the sound as "Bubble Bibble" or "Vubble Dwibble".

Voice Samples

32 years after the game's release, it was accidentally discovered that Double Dribble's voice samples were actually corrupted. More specifically, the DPCM samples are formatted correctly but the 2A07/2A03 (the sound chip in the NES/Family Computer) reads the bits in each of the sample's bytes backwards, causing the playback to sound very hissy or "crispy". Below are fixed versions of these samples, along with a unused sample thrown in the mix.

Description	In-Game version	Fixed version
"Double Dribble"
"Jump Ball"
"Free Throw"
"Dunk Shot" (Unused)

It's actually worth noting that this doesn't just affect Double Dribble: a wide variety of Nintendo games suffer from this exact issue.

A different title screen. Yup.

Intro

Japan	World

The intro was given a bit of the US of A. Palm trees (that are apparently as tall as skyscrapers) were added to the background (which as a whole was redrawn), the stadium was redrawn, the generic balloons are now all the same color, and the Konami logo balloons and blimp now carry the American flag.
