the United States, similar to the PlayChoice-10 for NES games. It consists of slightly modified Super NES hardware with a menu interface and 25-inch monitor, that allows gameplay for a certain amount of time depending on game credits. Manufacturing of this model was discontinued in 1992. Yellowing The ABS plastic used in the casing of some older Super NES and Super Famicom consoles is particularly susceptible to oxidization with exposure to air. This, along with the particularly light color of the original plastic, causes affected consoles to quickly become yellow; if the sections of the casing came from different batches of plastic, a "two-tone" effect results. This issue may be reversed with a method called Retrobrighting, where a mixture of chemicals is applied to the case and exposed to UV light. Game cartridge Super NES games are distributed on ROM cartridges, officially referred to as Game Pak in most Western regions, and as in Japan and parts of Latin America. Though the Super NES can address 128 Mbit, only 117.75 Mbit are actually available for cartridge use. A fairly normal mapping could easily address up to 95 Mbit of ROM data (48 Mbit at FastROM speed) with 8 Mbit of battery-backed RAM. Most available memory access controllers only support mappings of up to 32 Mbit. The largest games released (Tales of Phantasia and Star Ocean) contain 48 Mbit of ROM data, and the smallest games contain only 2 Mbit. Cartridges may also contain battery-backed SRAM to save the game state, extra working RAM, custom coprocessors, or any other hardware that will not exceed the maximum current rating of the console. Games 1757 Super NES games were officially released: 717 in North America (plus 4 championship cartridges), 521 in Europe, 1,448 in Japan, 231 on Satellaview, and 13 on Sufami Turbo. Many Super NES games have been called some of the greatest video games of all time, such as Super Mario World (1990), The Legend of Zelda: A Link to the Past (1991), Donkey Kong Country (1994), EarthBound (1994), Super Metroid (1994), and Yoshi's Island (1995). Many Super NES games have been rereleased several times, including on the Virtual Console, Super NES Classic Edition, and the classic games service on Nintendo Switch Online. All Game Boy games are playable with the Super Game Boy add-on. Many Super NES emulators have been produced. Mode 7 is a graphics mode that can simulate
