Dreamcast CODEBREAKER question

[MusicVideo]

I really cannot I believe I don't remember this correctly. I used to use CODEBREAKER for Dreamcast, and uhhh I it is a disc u put in your DC to cheat on games kinda like the old GAMESHARK but what I can't remember is does CODEBREAKER also come with its OWN VMU that u have to have to even allow the codes to work ??? Maybe someone understands what I'm talking about.
Cuz I seen it for sale on AMAZON but i swear I remember have something u had to put in the dreamcast controller as well as the disc that goes in the Dreacmast.
ahhhhh im so OLD

Codebreaker doesn't require a special VMU. GameShark does. Codebreaker makes a save file on your VMU unit itself where it stores codes you've added onto it but you can use a standard VMU. Not sure if you still need this bit of Info, since this topic is almost a year old but I figured I'd post here for anyone else who may want the info.
