I have a 3.2U system and want to use the SD card feature to store Wiiware titles rather than having in the Wii's memory.

I already have everything modded (HBC, cIOS38 rev 14 etc), but wondered what I need to install to get that feature.

Is it a particular IOS I need to load to get it or do I have to upgrade to 4.1? If I have to upgrade to 4.1, should I just use Waninkoko's upgrader and everything else will remain intact (or does it break anything)?

Thanks
