I'm trying to softmod a Wii for the first time but I have 2 problems. #1 The Wii's system ver. is 4.3u. The guides don't specify if the 4.3 softmod guides are compatible with 4.3u. I'll assume they're not and look for a way to downgrade my system ver. to 4.2. #2 I bought a Nintendo 4gb SDHC card. All the guides recommend an SD card some even specify SDHC cards will not work. Can the system version be downgraded? Will I be able to use my nintendo SDHC card?
