I was attempting to set up BrawlEx by following this tutorial here:
I moved my virtual sdcard to the my documents/dolphin emulator/wii folder. I installed the IOS36-64-3608.wad, and then set Super Smash Bros Brawl to the default iso. I then opened Gecko's boot.elf in dolphin, and changed the hook type to AXNextFrame. but when i select start game, it says no SD codes found and then tells me to please insert the Super Smash Bros Brawl game disc. I have double checked that Super Smash Bros Brawl is the default ISO and have also tried using the change disc option to no avail.
I'm using dolphin version 4.0-1722, windows 7 64 bit, and my Brawl is the NTSC version.
