Where does it freeze your Wii? If you mean that pressing A on the Wiimote won't respond when the screen tells you to, try pressing reset since that's what I have to do. Also, are you using the dol or elf file? I find that dol files works better than elfs on my Wii. Sometimes elf files work but then later on HBC will say they're not valid Wii apps.
Did you make sure you have the latest version of the app? I'm not sure what it is right now but it never froze for me. Try removing unnecessary stuff on your SD card, that might help.
I get all my apps off the homebrew browser. I'm sure it's the latest version. I don't have anything on my SD card besides the Extractor, Installer, GeckoOS, MenuLoader, and GC Booter. I'll try to use it without some of them and see if it works. I'll also try to re-download it.
Ok so I tried only having Extractor, Installer and GeckoOS on my SD card, no luck. I also tried re-downloading the apps, no luck either. It's ok though. I wasn't really dying to use the program, so I can live with my town looking the way it does. Thanks for your help Twozeronine
Sure, no prob. Just thought I'd help. What are you using for booting homebrew anyway?
On the side of your SD card there is a small switch. Slide that switch the other way. This turns read only on and off. It is possible save extractor is freezing because it cannot write to the SD card, only read it. Try that.
