SNES cartridges can indeed have custom chips to enhance game capabilities. These enhancement chips, like the Super FX chip, were used to provide features like improved 3D graphics that the SNES's main processor couldn't handle on its own.
Here's a breakdown of custom chips in SNES cartridges:
Enhancement Chips:
These are custom processors designed to add specific features to games, such as the Super FX chip for 3D graphics.
Super FX Chip:
This chip was particularly popular for games like Star Fox, which featured 3D polygonal graphics.
Other Enhancement Chips:
The DSP series (DSP-1, DSP-2, etc.) and SA-1 chip were also used in various games for different enhancements.
Coprocessors:
The CX4 chip, for example, was used by Capcom for specific graphics effects.
Reproduction Cartridges:
Modern reproduction cartridges allow users to create their own SNES cartridges with custom ROMs, potentially including enhancement chips if they can source them.
Flash Carts:
Flash cartridges like the SD2SNES (now FXPAK Pro) allow users to load ROMs onto a cartridge, sometimes with support for games using enhancement chips
