The **GameShark CDX** for the Sega Dreamcast was a popular cheat disc that allowed players to use cheat codes in Dreamcast games, similar to other GameShark devices on previous consoles. Here are some things to know about the GameShark CDX for the Dreamcast:

### Features
1. **Cheat Codes**: It allowed players to enter and use a variety of cheat codes for Dreamcast games, such as unlimited health, infinite ammo, and level skips.
2. **Import Game Enabler**: It also worked as a boot disc for playing import games, which made it popular among players wanting to play non-region-locked games.
3. **Code Updating**: Some versions had limited support for updating codes, but most were preloaded with cheats.
4. **Save States**: It provided options to save cheats to the Dreamcast memory card for easy access during gameplay.

### Usage Tips
1. **Insert the GameShark CDX Disc**: Boot up your Dreamcast with the CDX disc, and select or enter your cheats.
2. **Swap Discs**: Once the cheats are set, swap the disc for the game you want to play. The Dreamcast will then load the game with the selected cheats active.

### Notes
- The GameShark CDX can sometimes be hard to find in working condition today, as they were discontinued alongside the Dreamcast.
- While it enhanced gameplay, some users experienced crashes, especially with extensive cheats active.
