Dont know if anyone post anything about it, but here it goes:
If you need to pass a file from PC -> Amiga (if you want to convert ADF to real amiga disk) you can do this:
After you format a PC disk to 720kb you need to put the ADF (or other file) in it, but the adf is 880kb, so you may need to chop the file in smaller parts.
There is a program (15kb) called chooper (easy to find) that can chop the file.
Example:
In PC type:
CHOPPER S=#64 MYGAME.ADF MYGAME
it will chop the file in multiple 64kb files.
In Amiga type:
CHOPPER +J MYGAME MYGAME.ADF
In PC works nice, and i am sure that in amiga with Crossdos will work also.
There is also the Chopper file for the Amiga. Dont know if the Pc file will run in normal crossdos emulation. But there is a the Amiga file.
