Yes and IOS58 have not been touched. What is the brand/capacity of the HDD your are using? Just want to rule it out as being an issue. Is it a 2.5" or 3.5" drive. If 2.5" are you using a Y-Cable with both USB plugs plugged in?is this what you need?
Since Nintendont doesn't work when launched from HBC we need to find out why as if it doesn't work from there, it will never work from another loader.
