Tested in 32-bit WINE set to Windows 98 with DirectX9 installed via winetricks.
Instructions: mount the ISO file, run the executable, install preferred demos.
Some demos may require DirectX 8.0 or greater.
You can install demos via the launcher just fine, though installing manually could be more a more sure way to do so. Most demos will only launch via the installer if the game path is in Portuguese. Launching those demos manually is recommended instead.
Some hidden demos can be run directly from the CD, no need to install. You might have to manually extract them and give them read-write permission. Some hidden demos use MIDI, so you'll have to set it up if using Linux and WINE. Not all demos are guaranteed to work.
