Changing actual disk images will be "literrally" done, using the swap button i mentined before.
But, in direct file loading method, there is no meaning of "change disks" ,since you get rid of the disk images and access files directly!

So, for now, you can try to extract all files from all dsk images of a multi-image game, into a single folder. Then you can try to run game as usual.
Of course this method has some restrictions:
- Game must use Amsdos FILE routines and not sector/track loaders
- File names in different dsk images should have different names (otherwise you will have conflicts when extracted on the same folder)
If game fulfills the above conditions, then it should run without problem, since game code will be able to find all required files directly from the folder!
If you are in a mood, you can try some and give us the results
