Usb loader gx wiimmfi code question

Hi

I have my wii with homebrew channel and usb loader gx. There is a code inside the load menu to connect to wiimmfi

I use it and i am able to connect to the wifi network (i even appear in the gamestat section of the wiimmfi page) but so far i was unable to join to any match (tatsunoko vs capcom and smash bros brawl)

1) I am missing some extra config?
2) do i require openhost?
3) riiconnect24 is required?
4) should i patch the isos on my usb?

Just in case here is what i did:
Installing hbc
Installing usb loader gx
Creatimg wbfs partition
Wbfs manager to copy the games (they are working)
Opemimg a game (for example tatsunoko)
Seeing the message "connected to wifi"
Searching for random match
Waiting an eternity without results :( (they were like 5 players in tatsu and in smbb like 7)

Thanks a lot!

I was able to play smash bros

You need to add the friend's code if the people with who you wanna play and use play with friends (the random search doesnt works)

Still waiting to test tatsunoko
