I am trying to install Mac OS 9 on Windows Vista, however, all the files on the CD appear hidden. Can anyone help?
I think you need to post a bit more info - I assume you're using SheepShaver, and have got it properly installed complete with Boot Rom? (You should probably be aware that the Windows version of SS is rather flaky btw - and, at least in theory, only supports 98, 2000 and XP. If you want to use it on Vista, all bets are off).
I am not entirely confident from the tone of the first post that the OP is capable of setting up a cygwin environment, let alone compile Sheepshaver to run under Vista.
I was going to suggest BasiliskII, but I don't know if that tops out at System 7.5, which is all I ever ran on it. Cute, but pointless in the end.
