Hacking 4.0 vs. 4.1

[spritefreak]

I am wondering if 4.1 is free of any bugs. I am still on 3.2U firmware and I have been meaning to upgrade to 4.0U firmware. I was recently reading on the boards that some people were saying not to upgrade to 4.1 unless necessary. What is new with 4.1? I think I saw that Wii Sports Resort needs 4.1 correct?

Thanks in advance!

Use Waninkoko's 4.1 upgrader, and you're fine.

Wii Sports Resorts dose not need the 4.1 update it just fixes a bug in Wii Sports Resorts "Wii Motion Plus video".

You do need a loader that can load alternate dols tho.
USB Loader GX 648 and Back Up Loader Neogamma 6 can do this.
