Action Replay, GameShark, Gamebuster, GoldFinger, Equalizer (Datel/clones)
The Datel devices exist in various official/cloned hardware revisions, the DB25 connector requires a special Comms Link ISA card (or a "FiveWire" mod for making it compatible with normal PC parallel ports). Later "PAR3" models are said to not require Comms Link, and do thus probably work directly with normal parallel ports).

Xplorer/Xploder/X-Terminator (FCD/Blaze)
The FCD/Blaze devices are all same hardware-wise (with some cosmetic PCB revisions, and with extra SRAM and bigger FLASH installed in some carts). The DB25 connector can be directly connected to a PC parallel port.
