Is there a specific reason Dreamcast, Gamecube and Wii will not work with a Dell Optiplex 780 Intel Core Duo 8 gb ram and 2gb Geforce 610 card? I'm able to run Dreamcast on Lakka with same setup and Gamecube/Wii with RetroPie x86. Maybe a configuration needing to be changed? I'd like to help if possible. Thank you again for the hard work.
