I'm having this error. New CSS Icons show up as Random and crash when highlighting them I did what it to fix it, but it didn't work. Please help!
Make sure you have the "File Patch" Gecko code enabled (found in BrawlEx's Readme.txt file), and for Dolphin, make sure that you don't have the "sd.raw" file "open".I use something called ImDisk Virtual Disk Driver to make my computer think the "sd.raw" file is a plugged-in storage thing that I can then directly open and modify contents of, and Dolphin doesn't want to read "sd.raw" until I "eject"/disable the virtual disk of it.
Also for Dolphin, make sure "sd.raw" is located in the correct location. On a Windows system, this would be [your "Documents" folder]\Dolphin Emulator\Wii\sd.raw, regardless of where you've installed Dolphin. (If you've set up Dolphin to be portable (either through a .ini file or by having a file called "portable.txt" in Dolphin's installation folder), that'll be [path to Dolphin]\User\Wii\sd.raw instead.)
And make sure the folder structure on the SD card is correct. An example file would be X:\private\wii\app\RSBE\pf\BrawlEx\FigherConfig\Fighter3F.dat, where X would be the drive letter or root of the SD card. Additionally, make sure you have the "core files" of BrawlEx installed. An example file of that would be X:\private\wii\app\RSBE\pf\system\common2.pac.
Last of all, are you completely certain you set up the "cosmetic" files correctly?
