Is there an ADF emulator for use on an Amiga?

[Corrie]

I have unpacked some ADF files on my A4000 and when I try to run them
from disk, they usually crash, however running them on my old A500
they work fine. To get around this, is there an ADF emulator that I
could get for my A4000 so I can run them on my A4000???

My system:

A4000T
Cyberstorm MKIII 060 66Mhz
CybervisionPPC
128Mb RAM
Ultrawide SCSI HD

I have tried a number of things in an attempt to get the adf files to work, but most crash. Thats why I was after the emulator. I guess if all else fails, I can just use the A500, but I wanted them all on HD to run from one system...! After all that is the point isn't it...?
