BTW I have the source code for EMX.

the emx format is nothing more than an sector by sector image of the areas on the Emax 
floppies that contain data. I'm not a programmer in any way (unless you want some 
sprite graphice to run on your Commodore 64 :) But I do remember our threads about 
this back 9 years ago (OMG!!!) when Mike released what became the final version of 
EMX. Mike hasn't been among us for years and last I heard was not reposnding to 
emails about EMX. It's something he pieced together years ago for fellow users. I don't 
think he ever planned that this many people would have use or desire for it. Below is 
excerpts from the original Emax Manual wriiten by Mike:

This program was written on a HP Vectra 386/20. In addition to the bank and sample 
data, emx tacks a small header onto the front of saved disk files. This just identifies the 
emx version, and allows me to provide backwards compatibility should the need arise in 
the future. This adds 39 bytes to the size of the file, which is why 552999 is not a 
multiple of 2 or 512. 

emx is written using standard C, and compiled with Microsoft C v6.0. The source code is 
available 

Revision History: V1.0 First trial release. This uploaded the whole disc image, giving 
ginormous 819200 byte files for each disc image. V1.1 A little bird told me where the 
bank and sample data can be found on an Emax disc, so I was able to modify the 
program to only upload the relevant bits from the disc. This also helps out when 
downloading compressed banks created on an Emax II to an Emax I disc, as the 
operating system is no longer overwritten by emx. This release also added disc 
formatting to the emx menu, and the ability to upload/download just the operating system 
from an Emax disc.

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
