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.
• If you ever hear the term "J-cart," then this is referring to the special carts released by Codemasters that had two extra joystick ports built into the cartridge. This permitted four-way gameplay without a multitap adapter. Only six J-carts were released: Pete Sampras Tennis, Pete Sampras Tennis 96, Micro Machines 2, Micro Machines 96, Micro Machines Military Edition, and Super Skidmarks. All were later released as standard carts.
• Virtua Racing contains a DSP chip, allowing for enhanced graphics.
