its always been possible to store ST and all generic MFM disks in IPF format, but the scripts in the analyser are being worked on now.
creating an IPF is not just 'getting it into a format you can use in an emulator' we also have to ensure its authentic, unmodified etc. i.e "preserved", and the analyser does all that, and if you read the extensive WIP on the website you will see it's all analyser based progress.
so no, we're not hiding stuff behind our backs.
i hope your pretty suprise brings you much happiness.
