and one year after releasing Frogger (its final third-party game in the US) in 1998. In Japan, Nintendo continued production of both the Family Computer and the Super Famicom until September 25, 2003, and new games were produced until the year 2000, ending with the release of Metal Slader Glory Director's Cut on November 29, 2000. Many popular Super NES games were ported to the Game Boy Advance, which has similar video capabilities. In 2005, Nintendo announced that Super NES games would be made available for download via the Wii's Virtual Console service. On October 31, 2007, Nintendo Co., Ltd. announced that it would no longer repair Family Computer or Super Famicom systems due to an increasing shortage of the necessary parts. On March 3, 2016, Nintendo Co., Ltd. announced that it would bring Super NES games to the New Nintendo 3DS and New Nintendo 3DS XL (and later the New Nintendo 2DS XL) via its eShop download service. At the Nintendo Direct event on September 4, 2019, Nintendo announced that it would be bringing select Super NES games to the Nintendo Switch Online platform. Hardware Technical specifications The 16-bit design of the Super NES incorporates graphics and sound co-processors that perform tiling and simulated 3D effects, a palette of 32,768 colors, and 8-channel ADPCM audio. These base platform features, plus the ability to dramatically extend them all through substantial chip upgrades inside of each cartridge, represent a leap over the 8-bit NES generation and some significant advantages over 16-bit competitors such as the Genesis. CPU and RAM The CPU is a Ricoh 5A22, which is a derivative of the 16-bit WDC 65C816 microprocessor. In NTSC regions, its nominal clock speed is 3.58 MHz but the CPU will slow down to either 2.68 MHz or 1.79 MHz when accessing some slower peripherals. This CPU has an 8-bit data bus and two address buses. The 24-bit "Bus A" is designated for general accesses, and the 8-bit "Bus B" can access support chip registers such as the video and audio co-processors. The WDC 65C816 supports an 8-channel DMA unit, an 8-bit parallel I/O port a controller port interface circuits allowing serial and parallel access to controller data, a 16-bit multiplication and division unit, and circuitry for generating non-maskable interrupts on V-blank and IRQ interrupts on calculated screen positions. Early revisions of the 5A22 used in SHVC boards are prone to spontaneous failure
