	Games - Nintendo SA-1

The Nintendo SA-1 is a microprocessor developed by Nintendo for use in Super Nintendo Entertainment System (SNES) game cartridges. At its base, the SA-1 is an upgraded 65816-compatible coprocessor that runs alongside the SNES's 5A22 CPU (also a 65816-based processor). The coprocessor scheme allows the game console to process data faster.

The SA-1 as used in the SNES is not a slave CPU for the 5A22; both can interrupt each other independently.

Major features

The Nintendo SA-1 features a wide range of enhancements over the standard 65816:

Upgraded 10 MHz clock speed, up from a max of 3.58 MHz
Faster RAM
Memory mapping capabilities
Limited data storage and compression
New DMA modes such as bitmap to bitplane transfer
Built-in CIC lockout, for piracy protection and regional marketing control
Allowing far more detailed ACM graphics, as used in Super Mario RPG
