Just installed Dolphin, what can I do now?

Yesterday, I finally found out how to use dolphin (after an embarrassing amount of attempts.) So far, I homebrewed and installed WiiLink using my nand backup. Now I’m curious how I can play Wii games and how to add my custom theme on it. I tired using the mail patcher but I got this error.


Do I necessarily need it again or is it already installed? Also, the WiiMC Channel Installer gave me an error but loading into WiiMC through TBC worked just fine.

Thats all the questions I have for now, I’d love to hear your feedback!
