The y "trick" works. Is it normal that the screen is black even if no game is loaded?
For the record, I tried
this one and it works. Probably the first game doesn't work because it uses colors.
EDIT: I confirm this, the b&w version of the game works, even if with some problems.
If someone don't know how to find these games, there's a bunch of interactive novels at
IFDB database.
