Restoring "classic" Emulator For Osx 4.11 On Ibook, 'classic' on OSX4.11 (been wiped from systems folder) Options

[alreed]

I want to run an OS9 program on the iBook, and remembered that although I have the option of emulating it in "classic", I no longer have it on the System folder containing the emulator, just the icon (I remember getting rid of it thinking I wouldn't need it I think ).

Now I went and got a macbook, which also runs OSX 4.11 like the iBook, but unlike the iBook there's no Classic icon in its system preferences. Any suggestions? Do I take the game to the new macbook and hope to find Classic there, or is there a way I could get the emulator back on the iBook and play the game (Monkey Island4) on it ...which is what I'd planned to do before realizing the Classic had been deleted (due to trying to make memory space because of an earlier problem of untraceable memory loss- now fixed).

Thanks!
Sorry for the long sentences there...
