Usage

Nintendo optical discs are physical media used to distribute video games on three of Nintendo's consoles that followed the Nintendo 64. These are the GameCube Game Disc, Wii Optical Disc, and Wii U Optical Disc. The physical size of a GameCube Game Disc is that of a miniDVD; the Wii is based on DVD format, and Wii U Optical Discs are based on Blu-ray format. To maintain backward compatibility between generations of game consoles, GameCube discs are compatible with the first model of the Wii, and Wii Optical Discs are compatible with the Wii U. A burst cutting area is located at the inner ring of the disc surface. All official discs and their formats were manufactured and developed by Panasonic.

In 2017, Nintendo discontinued disc-based media in favor of game cards for the Wii U's successor, the Nintendo Switch, although it would license several more physically released Wii and Wii U games for many more months, with the last one being a port of Shakedown: Hawaii to both consoles in the summer of 2020.

GameCube Game Disc

The GameCube Game Disc (DOL-006) is the game medium for the GameCube, created by Matsushita/Panasonic, one of the ten founders of the DVD Forum, [1] [2] [3] [4] and later extended for use in the backward compatibility mode of the first model of Wii. [5] The GameCube is Nintendo's first optical disc console, after mainly ROM cartridge based platforms. The GameCube Game Disc is a 1.46 GB, [6] 8 cm miniDVD-based [7] technology which reads at a constant angular velocity (CAV). [8] It was chosen by Nintendo to prevent copyright infringement of its games, [4] [9] [3] to reduce manufacturing costs compared to Nintendo 64 Game Paks, [1] [4] [10] and to avoid licensing fees to the DVD Forum. [1] [4] [ failed verification ] GameCube Game Discs do not use the Content Scramble System found on normal DVD-Video discs, as Nintendo was not satisfied with its level of security. [3] [ failed verification ]

The GameCube is not able to be used as a general DVD player, except for the Panasonic Q which is a uniquely customized GameCube with DVD capability that was released only in Japan. [4] [11]

Some GameCube games with large amounts of data span two discs, such as Resident Evil 4 , Baten Kaitos , and Tales of Symphonia . Some multi-platform games that fit on single discs for PlayStation 2 and Xbox had certain features removed in order to fit on GameCube Game Discs. Full-motion video (FMV) scenes and audio clips have higher compression or lower quality to fit on a single disc.

Wii Optical Disc

The Wii Optical Disc (RVL-006) is the physical game medium for the Wii, created by Panasonic. Nintendo extended its proprietary technology to use a full size 12 cm, 4.7/8.54 GB DVD-based [12] disc, retaining the benefits of the GameCube Game Disc, and adding the standard capacity of a double-layer DVD-ROM. Wii Discs always include a partition with files to update the Wii system software, which are installed before starting the game if needed. This ensures that systems that cannot connect to the Internet are still updated. [13] For the same reasons as the GameCube, the Wii cannot play DVD movies or CDs. However, earlier Wiis can play DVDs using homebrew such as WiiMC. [14]

The Wii can read dual-layer discs, and all games are single-layer prior to the release of Super Smash Bros. Brawl . [15] [16] Upon that release, Nintendo admitted that some Wii systems may have trouble reading dual-layer discs due to a dirty laser lens. [16] [17] Nintendo repaired systems with dual-layer problems, [16] [18] and later released a disc cleaning kit for users to purchase. [19]

Wii U Optical Disc

The Wii U Optical Disc (WUP-006) is the retail physical game medium for the Wii U, with a capacity of 25 GB. There is no 50 GB dual layer version. The Wii U system software is backwards compatible with Wii Optical Discs, but not with GameCube game discs. [20] The Wii U Optical Discs differ in appearance from most other optical discs in that they have soft, rounded edges. [21]

The console's optical drive was developed and supplied by Panasonic, [22] a founding member in the Blu-ray Disc Association. [23] It is not clear whether the Wii U Optical Disc is similar in physical design to the Blu-ray physical disc specification.[ clarification needed ] Nintendo president Satoru Iwata stated, "Wii U does not have DVD or Blu-ray playback capabilities. The reason for that is that we feel that enough people already have devices that are capable of playing DVDs and Blu-ray, such that it didn't warrant the cost involved to build that functionality into the Wii U console because of the patents related to those technologies". Like with the GameCube and Wii optical discs, it was chosen by Nintendo to prevent copyright infringement of games, to reduce cost by avoiding licensing fees to the Blu-ray Disc Association (BDA), and to reduce loading times. This also prevents the console from being modified into a DVD or Blu-ray movie player. [24] [25]

Burst cutting area

Each Nintendo optical disc contains a burst cutting area (BCA) mark, a type of barcode that is written to the disc with a YAG laser. The data stored in this BCA mark includes an encrypted table related to the hardware-based copy-protection mechanics, in addition to 64 bytes of un-encrypted user-accessible data. [26] Wii U discs do not use BCA.

A BCA mark is visible to the naked eye. It is different from the IFPI mark that is on all optical discs. BCA is described in Annex K of the physical specification, and can be seen between radius 22.3±0.4 mm and 23.5±0.5 mm. There are also six additional evenly spaced small cuts, visible with a strong light source, located just outside the BCA radius, which are related to the copy-protection. [26] Their value as a copy protection mechanism diminished after Datel discovered that the same pattern could be recorded into the DVD instead of needing to be precisely cut later. [27]

New Super Mario Bros. Wii was the first Wii game to use the BCA as part of an anti-piracy check; however it was cracked.[ citation needed ]

The history of video game consoles, both home and handheld, had their origins in the 1970s. The concept of home consoles used to play games on a television set was founded by the 1972 Magnavox Odyssey, first conceived by Ralph H. Baer in 1966. Handheld consoles bore out from electro-mechanical games that had used mechanical controls and light-emitting diodes (LED) as visual indicators. Handheld electronic games had replaced the mechanical controls with electronic and digital components, and with the introduction of Liquid-crystal display (LCD) to create video-like screens with programmable pixels, systems like the Microvision and the Game & Watch became the first handheld video game consoles, and fully realized by the Game Boy system.

Homebrew, when applied to video games, refers to games produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs. Many consoles have hardware restrictions to prevent unauthorized development.

Video game packaging refers to the physical storage of the contents of a PC or console game, both for safekeeping and shop display. In the past, a number of materials and packaging designs were used, mostly paperboard or plastic. Today, most physical game releases are shipped in (CD) jewel cases or (DVD) keep cases, with little differences between them.

The seventh generation of home video game consoles began on November 22, 2005, with the release of Microsoft's Xbox 360 home console. This was followed by the release of Sony's PlayStation 3 on November 17, 2006, and Nintendo's Wii on November 19, 2006. Each new console introduced new technologies. The Xbox 360 offered games rendered natively at high-definition video (HD) resolutions, the PlayStation 3 offered HD movie playback via a built-in 3D Blu-ray Disc player, and the Wii focused on integrating controllers with movement sensors as well as joysticks. Some Wii controllers could be moved about to control in-game actions, which enabled players to simulate real-world actions through movement during gameplay. By this generation, video game consoles had become an important part of the global IT infrastructure; it is estimated that video game consoles represented 25% of the world's general-purpose computational power in 2007.
