How does it play compaired to nintendos wifi. Is it still laggy
Now that I'm full I can explain
OK yes it still laggy and everything else is the same as brawl so nothing chance expect to be able to play online.
OK the new server is Called Wimmfi as alternative server to play online
I really don't know if you willing to do all this since smash 4 wii u version will be coming this month but:
First you need to ERASE all your data and custom stage too that include the sample but in the guide that I put you there is alternative way to get all characters in one piece
Second you really need a memory card (SD card) and must be less or equal 2GB so no more than that
Third there is two way one is the hackless method and the other is the homebrew method so I picked the hackless with geckko one because it was very easy to do and the rest watch the video and read all the instruction in the guide carefully and thats all.
if you have any question feel free to ask me or in the guide as for me do it through private message (Conversation)
Good luck and See you around
