Space Trouble

Hi everybody,

I have a question about a game from Hal Laboratory. It concerns the game Space Trouble, a simple 1984 shooter.

I know for certain that this game was also published under a different name, the game was exactly the same, except for the title screen which had of course another title.

Does anybody know or remember what that name was and if it was published by Hal itself or a third party.

Thanks in advance.
