Tonight I got my WiiU and my copy of smash brothers. I grabbed my 2GB SD card, I copied over smash stack and BOOT.ELF from boot me. I updated the WiiU like it asked me to, So I could get to the vWii. Then I disconnect my Wi-Fi. I put in smash brothers and boot it up, I do not let it make any save files. I get to the main menu and then I push my SD card in and select level builder. it searches for like 3 seconds, Then the screen freezes and nothing happens. It get a high pitch sound from the game, So does anyone know what I am doing wrong? Or what could be causing this? I have tried 2 different SD cards.
