Everyone with a wiikey and 1.9g and up firmware suffers from 3x speed as well(myself included). They only time i got problems was with SSBB videos. Excite truck loaded much faster than 2 minutes maybe the iso patching is what makes the iso loader slow.
You cant. They are encrypted with your old wii rsa key so the new wii can not decrypt them. Try finding the wads off the internet. To make wads off your channels you need the do a NAND FS dump and since you sold the wii you cant do one.
I have tried searching the web, but i cant find the tools to extract the ssbb soundtrack. Can someone help me because i want to encode it in flac so i wont lose any quality, and all the soundtrack rips i found are in mp3.
Glueing a piece of wire will probably work, but that kind of soldering you need to bridge two points so close to each other can be done even with a lighter -.- .
Well you can change the region to jap, install the jap shop channel and then revert to usa and run StarFall. This should allow you to have region free channels so you will be able to run the jap shop channel.
System menu 258 is just 3.1e. 3.2E has not been released in any game. To get to it you must go here : http://hackmii.com/2008/05/semi-brick-fix-discs/ . Download the PAL update, burn it and put it on your wii. It should ask you for an update which will get you to 3.2e.
