the rockchip can emulate but i hazard a guess that your players firmware has not, not, been optimized for this and you will not even have enough buttons to play the games anyway, this wont work on yours and there is no fix for it
these, players uses std firmware, altered for each player, but not done very well im afraid
as for modding, not sure on this site but see here for tool and tutorial

also, make sure you use the RK27UIEditor for your player
