Just a quick update for those who are stil interested in this topic & also to re-iterate that you do this at your own risk.
I have just read that the guy who is doing these custom files has just posted that he stuffed his unit again
![EEK!](images/smilies/eek.gif)
when testing an image he had converted.
All the images on his site have been tested on his system, but there is no guarantee that they will not stuff up your system.
