I've been reading this guide and it seems pretty straight forward. Seems like a sweet way of backing up all your Wii games to a hard drive so that you don't have to keep putting the discs in. The laser in my drive has been failing so it seems like a pretty good option. How to Back Up and Play Your Wii Games from an External Hard Drive Has anyone actually tried this? Is there any chance of breaking my Wii forever? For those who have already tried it, did you get banned from playing online?

Take a look at the performance String.Format at: http://blogs.msdn.com/ricom/archive/2004/03/12/88715.aspx

In summary, ”
Even though it’s the worst performing, and we knew that much in advance, both of your CLR Performance Architects concur that #2 [Using String.Format] should be the default choice. In the highly unlikely event that it becomes a perf problem the issue is readily addressable with only modest local changes. Normally you’re just cashing-in on some nice maintainability. We do not alter our choice given the data below”

Take a look at how much more readable your code is is after using string.format. This code takes a raw phone number and adds brackets to it for formatting (VB.NET example)

Before:

‘strPhone = “(” & strPhone.Substring(0, 3) & “)” & strPhone.Substring(3, 3) & _
‘ “-” & strPhone.Substring(6, 4)

After:

strPhone = string.Format(“({0}){1}-{2}”, strPhone.Substring(0, 3), strPhone.Substring(3, 3), strPhone.Substring(6, 4))
