List of Super NES enhancement chips

This standardized selection of chips was available to licensed developers, to increase system performance and features for each game cartridge.

[2] It is typically programmed to act as a graphics accelerator chip that draws polygons and advanced 2D effects to a frame buffer in the RAM sitting adjacent to it.

[3] The Cx4 chip is a math coprocessor used by Capcom and produced by Hitachi (now Renesas) to perform general trigonometric calculations for wireframe effects, sprite positioning, and rotation.

[6] This series of fixed-point digital signal processor chips provides fast vector-based calculations, bitmap conversions, 2D and 3D coordinate transformations, and other functions.

It is used as a math coprocessor in games such as Super Mario Kart and Pilotwings that require more advanced Mode 7 scaling and rotation.

[10] The DSP-1B introduced a bug in the Pilotwings demo due to the game code not being updated for the timing differences of the chip revisions.

Its primary purpose is to convert Atari ST bitmap image data into the Super NES bitplane format.

[16] Because the Super NES is not powerful enough for software emulation of the Game Boy, the hardware for the entire handheld is inside of the cartridge.

The chip manages communication with the kiosks to download ROM images, and provides game selection menu.

[19] OBC-1 is a sprite manipulation chip used exclusively in the Super Scope game Metal Combat: Falcon's Revenge, the sequel to Battle Clash.

[2] The Rockwell RC96V24DP is a low power, V.22 bis 2400 bit/s data/fax modem data pump in a single VLSI package,[20] used in the XBAND cartridge.

However, the controlling 5A22 processor may still request normal, uncompressed data from the game's ROM even if the S-DD1 is already busy with a decompression operation.

Emulation of the S-DD1 was initially difficult, requiring "graphics packs" to be provided for the affected games, until the compression algorithm was identified.

The SA1 also features a range of enhancements over the standard 65C816: A data decompression chip designed by Epson, used in three games by Hudson.
