keyboard issues in wii games HELP!

[STOCKMAN]

Last time i used dolphin was about a month ago when i tested sonic and the secret rings on dolphin 2688. While the game works great i have some realy serious issues playing with the keyboard. Sonic runs forward all the time i am stuck on leve3 where you must defeat 10 enemies because i fall down! That i why i gave up and i havent use dolphin since then. So i would like to know is there any way to make wii games work ok with keyboard+ mouse?? At least fps games like metroid prime3 for example will it be playble with keyboard?? Please help, i want to play sonic and some other wii games and i cant due to the keyboard issues!
