Formatting can mean either removing everything from a memory device or changing the format of the memory device to something else (ie Fat32 to NTFS), which usually requires all of the data on the device to be removed.

Defragmenting is going through the device and fixing pieces where a mistake could have been made while writing the data to the device (fragments).

I wouldn't think defragmenting the SD card would damage it, but I've never looked into it so don't take my word for it.

Yup. Not sure if this helps any, but when I was troubleshooting I found that when I had the hook type set to none it wouldn't freeze, but it'd load normal brawl without any hacks.

Thanks for the response. (Still have the issue)

I added a character to the normal version of Brawl (using Sammi Husky's Clone tool) and when I played it on my Wii it worked great the first time, but after that it always froze at the "Online Interactions Not Rated by the ESRB" screen that shows right after the Wii strap screen.

So after trouble shooting that problem for some time I figured I'd just download someone else's BrawlEx pack. Well, that worked well on the first run, but now it seems to freeze on ESRB screen about 95% of the time. It's odd that it works on rare occasions; not sure what'd cause something like that.

Thanks for any help!

I downloaded a BrawlEx pack that worked great once, but now whenever I try to load it up again it freezes at the ESRB screen. I noticed a few other people posted about this, but is there a fix or anything for it?

I downloaded and installed the latest version of the Deadpool over Snake PSA (Deadpool Pack, New Recolors + New Model + New Css Stuff (Final PSA) by cheatglitch, KTH, BeyondYou, Wolfric, SiLeNtDo0m, Hagure, JCentavo) and it currently freezes Brawl as soon as a game ends (such as a 2-minute ko fest). Everything works well up until that point. I downloaded and installed of the files twice, so I don't believe it was a bad download. Is there anything I could do to fix this? It's also probably worth noting that I've only been hacking Brawl for about a week, but I have had no notable problems with any other PSA.

Thanks,
