Nintendo 64DD emulator for emuelec

Hello everyone. I’m new on emuelec and now more than ever because I changed my device S912 for a s905x3. I was having problems to emulate emuelec because I was using a usb pendrive but now I changed into a SD card and works much better. I wanna ask If there is a 64DD emulator and also… what can I do to have a better performance in Nintedo 64, 3DO and Saturn?

if Mupen64 does not support 64DD then no, there is no support for it.
