The Dreamcast ended up getting a fair amount of accessories, some of which were pretty standard, things like the Jump Pack or the Arcade Stick. However, it also got a fair amount of uniquely Dreamcast accessories, like the fishing rod or the keyboard, which give the console that much more character during its 1998-2001 run. Just to note, the Dreamcast controller and the Dreamcast VMU will not be covered as they were covered in other sections since they've had their variants covered already.
One of the most important accessories for the Dreamcast was the Jump Pack, also commonly known as the Rumble Pack. The Jump Pack plugs into one of the two Dreamcast controller slots, usually the back one as the VMU occupies the front slot, to provide rumble feedback during gameplay. The vast majority of the Dreamcast library supports it. The Dreamcast was the last console to come with a seperate accessory for the rumble/vibration feature.

Introduced as a solution to the VMU's rather small storage, the 4X Memory Card as it's name implies has 4 times the memory. Due to the quirks of the Dreamcast, the user had to 'switch' from each memory with the use of a button on the memory card and the LEDs on the memory card will show which "card" you are currently using. It was only available in North America and Japan.

As part of the Dreamcast's online focus, Sega released various accessories related to online gaming, one of them is the Dreamcast Keyboard. It is a standard PC keyboard but for the Sega Dreamcast. Alongside the Dreamcast Mouse (mentioned below), it served to emulated the "keyboard and mouse" style of gaming that was popular on PCs and serves as a great alternative way of playing First Person Shooters like Quake III Arena on Dreamcast. Typing of the Dead is a unique take on the arcade lightgun genre!
Model Number:HKT-7620(NA)—HKT-7630(EU) Price:$24.99—£19.99
As mentioned above for the Keyboard, the Mouse was a part of Sega's online focus with the Dreamcast. As the Dreamcast was capable of browsing the internet, the mouse proved most useful. It also was the best way to play First Person Shooters on Dreamcast alongside the keyboard.

One of the more unique accessories in a list of fairly unique accessories the Dreamcast Microphone was initially developed solely for the game Seaman. It wasn't utilized very much by by more than a dozen and half games. Planet Ring and Alien Front Online are two games that used the Microphone for online-play, pioneering this form of online communication.
Only released in North America and Japan (the device was not region-locked), the Broadband Adapter was an upgrade over the standard Modem that came with every Dreamcast console, giving the console higher internet speeds. However, there is a downside to this. Due to its rather late release and the necessity for developers to specifically include the device when programming games, only a small selection of 14 games actually used the Broadband Adapter.
Model Number:MK-50176 Price:$59.99
Due to the Dreamcast's solid selection of 2D fighting and shoot-em-ups, the Dreamcast got the arcade stick as an option for the more dedicated fans of Capcom in particular. It brought home the feel and build-quality of the arcades. It had only one slot, presumably for the VMU.

The dying gasp of a popular genre during the 1990s, the light gun brought the arcade feeling home with the ability to shoot bad guys with a plastic gun. Something that isn't possible anymore due to the end of the CRT. Unfortunately, the Dreamcast didn't get many light gun games with only 7 games. There is also the fact the US lightgun doesn't exist due to the Columbine school shooting of April 1999. US versions of light gun games don't work with light guns.
Model Number:HKT-7800 Price:£24.99
Only released in Japan and only for one game: Cyber Troopers Virtual On. Fairly underwhelming.
Model Number:MK-50151/HKT-7400(NA)—MK-55151(EU) Price:$59.99—£44.99
A fairly common accessory for game consoles during the 3D era of the 1990s and early 2000s due to the prevalence and popularity of racing games, a racing wheel was of course available for Sega's Dreamcast! 44 games are compatible with the official Dreamcast wheel. It is important to note that the wheel does have the best reputation with racing game fans.

One of the more famous Dreamcast accessories, the Fishing Rod was released on the console's US launch to accompany Sega Bass Fishing. The fishing rod worked with 6 dedicated fishing games and provided an arcade-style experience for Sega gamers at home.
