Editing Bank switching (section)

== Video game consoles ==
Bank switching was also used in some [[video game console]]s.<ref name="Carey_2002"/> The [[Atari 2600]], for instance, could only address 4&nbsp;KB of ROM, so later 2600 [[game cartridge]]s contained their own bank switching hardware in order to permit the use of more ROM and thus allow for more sophisticated games (via more program code and, equally important, larger amounts of game data such as graphics and different game stages).<ref name="Grand_2004"/> The [[Nintendo Entertainment System]] contained a modified [[MOS Technology 6502|6502]] but its cartridges sometimes contained a [[megabit]] or more of ROM, addressed via bank switching called a [[Multi-Memory Controller]]. [[Game Boy]] cartridges used a chip called MBC (Memory Bank Controller), which not only offered ROM bank switching, but also cartridge [[Static random-access memory|SRAM]] bank switching, and even access to such peripherals as [[Infrared|infrared links]] or rumble motors. Bank switching was still being used on later game systems. Several Sega [[Mega Drive]] cartridges, such as [[Super Street Fighter II]] were over 4&nbsp;MB in size and required the use of this technique (4&nbsp;MB being the maximum address size).
The [[GP2X]] handheld from Gamepark Holdings uses bank switching in order to control the start address (or memory offset) for the second processor.
