I made this thing in 2003. It is a patched version of the Indy application that lets you play this game on Power Macintosh.
Drag the application “Indy™ PPC” into your Indy™ game folder so that you can use it instead of the original unworking version. Remember to set your monitor’s color depth to 256 colours before playing.
Known Bugs: Characters appear in wrong colours and inventory item names looks corrupted when using MacOS 8.1 or an older system version.
