Gecko problems

[Thatguy]

I've been using gecko 1.9.2 and recently 1.9.3 on a 4.1j wii; other games work fine yet when trying to boot up Clash of ninja revolution 3 the game starts but then cuts to a black screen. And Radiant dawn does not reset instead it reboots the system. Do these games not work with gecko? Or do they contain an update that is not compatible?  Any help would be appreciated.
