Dreamcast third-party Jump Packs
From Sega Retro
The Sega Dreamcast was the last mainstream video game console to have detachable rumble/vibration (or in the Dreamcast's case, "jump") packs to help immerse the player within the game. The official Jump Pack was often seen as expensive, bulky and heavy, so several third party manufacturers produced their own. Also unlike the VMU, Sega only produced the Jump Pack in one colour—white.
There are some interesting third party variants of the Jump Pack. For example, Mad Catz's "Force Pack" has an LED which flickers when vibrating.
This page lists all of the third party jump packs we know about. It is likely incomplete.

Jump pack/memory card hybrids
Some third-party manufacturers chose to combine the features of a Jump Pack with that of a Visual Memory Unit (sans screen and buttons), creating an accessory that could both cause a controller to vibrate, and allow game data to be saved. Sega never released this style of hybrid accessory themselves - you were always expected to buy each individually. Most of these are styled similarly to a standard Jump Pack, i.e. with a hangover at the top, making them better suited to the second port of a Dreamcast Controller.
Not all hybrid units can work as both accessories - Nyko's DC Hyper Pak, for example, has a switch on top that toggles between rumble or memory, being unable to perform both functions simultaneously. Alternatives to this scheme were building vibration functions into the controller itself, which several third-parties also did.
