Dolphin without wiimote/with guitar hero drum?

[Nickd]

hello,

I'm new to this, i checked a couple threads, but didn't exactly find an answer.

I am interested in playing mario games on dolphin + that new donkey kong game, but I dont have a wii mote, is it possible to play these with the keyboard only?, or is it possible to use your mouse?
i found this: http://forums.ngemu.com/dolphin-discussion/114383-can-i-play-games-without-wii-mote.html but it wasnt very usefull

I allso like to play rockband and guitar hero games, is it possible to connect your ps3 guitar hero drum and/or guitar to dolphin?

+ my specs are: intel core 2 duo cpu, e8400 @ 3.00 GHz, 8GB ram, 64 bits --> will these games work on my pc?

Thanks
