FAQ

Q: Can I use a Dreamcast mouse or keyboard on a computer like a normal mouse or keyboard?
A: Yes! You will need to enable mouse (or keyboard) mode using the adapter manager first (version 2.1.22 or newer required), then it (your mouse or keyboard) will work as a perfectly normal USB keyboard or mouse would.
(Warning: Keyboard mode may not work in your computer BIOS or on some video game consoles which want to communicate using the 'boot protocol' which this adapater does not implement yet.)

Q: What is the difference between the old version (ADAP-DC-USB) and this new version (ADAP-DC-USB_v2) ?
A: The form factor has changed (the USB cable can now be removed) and the electronics were updated for lower latency. Also, more peripherals are supported and the mouse wheel works.

Q: How can I tell which firmware version I have?
A: If the product number written on the adapter is ADAP-DC-USB, you have an old firmware (older than version 2) that cannot be updated. If you have a new adapter, you can use our adapter manager to check the firmware version currently installed.

Q: Is this adapter available in other colors?
A: At the moment the gray Dreamcast cable with the black adapter casing is the only option.
