The files in the "All Systems" folder are needed on all systems ! These files should be copied to your Extensions folder inside your System folder.
Don't copy the "All Systems" folder to your extensions folder, just the files inside it. Otherwise your system will not find the extensions
If you are running versions of MacOS between 7.1.2 and 7.5.1 inclusive (Select "About this Macintosh" from the Apple menu to find out which system version you are running) you need the file "Display Enabler" from the "7.1.2 - 7.5.1" folder. This should also be placed in the Extensions folder inside your System folder.
If you are running versions of MacOS between 7.1.2 and 7.5.2 inclusive you also need the file "Display Library" from the "7.1.2 - 7.5.2" folder. Again, this should be placed in the Extensions folder inside your System folder.
If you have a 68K Macintosh (that is, one which does not have a PowerPC processor) you also need to install CFM68K. Follow the instructions in the document "How to Install CFM-68K" in the CFM68K 4.0 folder.
In the "Optional Input Extensions" folder you will find "Input Sprocket" drivers for various input devices. Input Sprockets is Apple's software which allows games to use a wide range of input devices with simple customisation. If you have a device which corresponds to the name of one of these drivers (all devices from CH (e.g. JetStick, FlightStick Pro) use the "Input Sprocket CH" driver)) you should place the driver in your Extensions folder to use the device.
