Re: D9090 back to life !

I completely agree with Spiro. A disk image is an archive format and should 
not be modified from the original. I'd rather add something at the end instead.

Broken BAM or Dir sectors due to overwritten data might wreak more havok 
with tools that do not know them than ignoring extra data at the end of file
