| Sound: The battle is only accompanied by some sound effects,
| e.g. during shooting and explosions. However, Gorf is known for an at

Wizard Of Wor might be another game, what has in its cartridge format
speech synthesis. But the images I tried also don't work.
I downloaded a .bin file for VICE and then the Magic Sound option
activated .
