Looks like the NES game and the computer games are different releases. One is Westwood and the other is LJN. One looks top-down and the other is side-scroller. I'm not familiar with the computer versions, but the NES has a "sleep" meter and a secondary dream world... sounds like those are not present on the computer?
I'm sitting on an ancient correction WIP sent back saying: yes, these are separate. No, we won't do anything about it until you make a new game entry for the one that needs to be split off.
I haven't; perhaps you'd like to?
For what it's worth, this is apparently the established protocol for all game splits. You've got to care enough to create the new vessel for the split content to flow into 8)
This I did not know. Maybe I will do it. I should check and see about any other splits I have pending.
It would be nice if this was mentioned somewhere instead of gathering dust in the queue ;P
Edit: New entry is done.
