MZ-2500: Fixed the floppy "reverse" register, which actually changes the way floppy drives are accessed (don't ask). this makes Laydock to get further, but it hangs at some point due of a PIT timer bug (the handler gets screwy at some point during the T&E Soft animation).

If you press ENTER as soon as T&E Soft appears, then you can enter into gameplay.
