Sega Dreamcast

Installing USB-GDROM

This procedure involves opening your Dreamcast and removing the optical drive. USB-GDROM supports both VA0 and VA1 boards, but you must still work carefully. Use a static-safe surface, never force a connector, and proceed only if you accept the risk to your console.

USB-GDROM installs much like other ODEs, with the bonus of automatic region patching once running. Work through the phases in order.

Prepare storage
Load your USB stick or SD card with images in GDI or CDI format. Back up your VMU saves before opening anything.
Open the console
Remove the underside screws, including the tri-wing, and lift the top shell, minding the internal cabling.
Remove the GD-ROM drive
Unscrew the original optical drive and lift it out, disconnecting its ribbon and power leads gently.
Install the USB-GDROM
Connect the board to the drive connector, following the orientation in the manufacturer's instructions, and secure it so nothing shifts.
Connect storage and test
Attach your USB or SD storage, reassemble enough to power on, and confirm a game loads with region patching working before closing up.

Imports just work

Thanks to on-the-fly region patching, you generally do not need to patch images individually. Insert a foreign title and it should boot.
