The Classic Mac versions of the Monkey Island games are on the HDF somewhere, they're pretty good.
No, they're not on the HDF. The HDF only contains a basic OS8.1 installation. If you mean the Mac zip file, that thing is 387Mb! It would take me about 60 hours of straight download time.
Even if they were on the HDF, it's no good for me - they require a minimum of 256 colours.
