Serial SD card adapter
The serial SD card adapter is a community-designed peripheral that allows software to access an SD card for reading and writing through the Dreamcast's serial connector. Files can be accessed and manipulated using DreamShell. Code and games can be executed from the SD card, but because access is limited by the slow serial connectivity, running commercial games in this way is typically slow and buggy. Gamers looking to play games via SD card should look for an optical drive replacement instead.
