Game Boy Color

Background
The Game Boy Color (commonly abbreviated as GBC) is a handheld game console, manufactured by Nintendo, which was released in Japan on October 21, 1998 and to international markets that November. It is the successor to the Game Boy and is part of the Game Boy product line.

Logo (October 21, 1998-July 18, 2003)
The logo in the second video can be seen at 1:03

Visuals: On a white background, we see the text "GAME BOY" appearing letter-by-letter, with rainbow colors scrolling through. When a cartridge is inserted, the Nintendo logo appears below it in black.

Variants:
 * Like the original Game Boy, if the cartridge is not inserted, the Nintendo logo is replaced with a black rectangle, however the registered trademark symbol is still intact.
 * Like the original Game Boy, if the cartridge isn't all the way in or is corrupted, the Nintendo logo is a mess of pixels.
 * On Japanese commercials, there is a flash with the text forming itself in a similar style to The Matrix.

Technique: 2D sprite animation.

Audio: The "bling" sound from the Game Boy logo when it is complete.

Audio Variant: On the Japanese commercials, a male announcer says "GAME BOY COLOR".

Availability:
 * Seen on all Game Boy Color games.
 * This logo is also used to plaster over the original Game Boy logo when starting up an original GB game on the Nintendo 64 and Nintendo GameCube.
 * Also used while playing classic Game Boy games on the Game Boy Color or Game Boy Advance (SP).
 * The best way to find a Game Boy Color game is look for a gray banner on the left side of the box with "GAME BOY COLOR" filling the rest of the banner.
 * It is also intact on Generation 2 Pokémon games when played on the GB Tower mode in Pokémon Stadium 2.
