I know that if you've looked for Amiga games before, you've run across those damn LHA files. I found out that these are files that allow games which were originally designed to run from floppy disks to an Amiga hard drive.
You're supposed to be able to simulate an Amiga hard drive from what I've read. So, if you download
WHDload you should be able to emulate the Amiga hard drive and run WHDload from an emulator, which installs the LHA files.
Is this right? Maybe from there you can somehow convert the file to ADF format?
