Troubleshooting your Duo

CD Games are not working

Directly connecting 8BitDo 2.4G controllers

The CD/Disc won't eject

Difficulty playing original media

How do I play an audio CD or CD+G in Duo?

I have a HuCard that outputs CD audio, but I can’t hear anything?

Why won't my games save?

How do I manage data in the backup RAM?

What do I need to play a 5-player game like Bomberman?

Can I play a six button game without an original controller?
