Cartridge

A cartridge stores a game's ROM data, and in some cases also contains additional hardware such as the battery-powered SRAM.

• The Sonic & Knuckles cartridge has another cartridge slot on top of it, similar to Game Genie and Pro Action Replay carts. This is Lock-On Technology.
• Micro Machines 96 has two additional joypad ports on the front of the cartridge, making it a "J-Cart".
• Virtua Racing contains a DSP chip, allowing for enhanced graphics.
