The PreFab Player trial version is available here:
http://prefabsoftware.com/player/player ... rsion.html
And Scott Lawton provided this registration code to unlock the trial software for more than 30 days and make it a full version.
Scott Lawton confirms (in an e-mail to me) that he is making the software freely available to anyone.1616-150E-2103-4012
I am using the PreFab Player very successfully in SheepShaver running OS 9.0.4. I haven't tested it in Basilisk or in other Mac OS versions.
I'm very grateful to Scott, and I expect many other people will be too.
