Best airmouse/keyboard remote for Zidoo x9s

Hi guys, any views about the best airmouse/keyboard remote for this device?

My research shows that Minix A2 is one of the best out there, but it seems to be optimized for Minix boxes. Does anyone have experience using it with the x9s?
Has anyone tried adding/editing the key layout file to work with this remote?

Any input on selecting the right airmouse/keyboard remote is welcome.
