Beginner needs help with the setup of rom collection browser and dolphin for wii
Could someone please help me?! Thanks in advanve!!!

My base:
cubox i4-Pro (Quadcore i.MX6 Chipset / 2 GByte DDR3 1066 RAM / GC2000 GPU)
OpenELEC Version 5.0.5
Rom Collection Browser Version 2.1.2
emu dolphin V4.3.2


The problem is that I have no knowledge abot the right steps.
I think I have done a lot of mistakes by chosing the wrong pathes, scrapers, parameters and so on.
So I could not import the games.
The next problem is that only the first start of RCB allows you to configure all parameters and pathes?!
Is someone able to describe the configuration step by step for absolut beginners.

My wii games are wbfs-files, but i have read that this should be no problem for the dolphin emu.
How should this games be named because there are .png-cover pictures for this games in an other path.
Game and picture have only a (the same) code-name like "R3DPS5". The name of the game can only be seen in the file name above.

Help would be really great. Thanks again and best regards!
