C64 emulation is very tricky. Sometimes games run too fast, sometimes they don&#x27;t run at all. The C64 floppy drive is a constant source of pain for emulation, as most games and software actually included their own drivers for the floppy drive to make it work better...<p>Fiddle with the floppy drive settings and emulation configs around them.<p>The other thing is that most games require a joystick, so make sure you&#x27;ve configured one in settings. That said, space bar or joystick button generally starts games, but not always.
