Home Alone

Final level with all items:
Press Up, Down, Right, Left, Select at the title screen.

Hint: Hidden room:
Play to near the end level 3 of the attic. Jump through the wall instead of dropping down at the end of the level as usual. You will land in a hidden room that contains various items.

Hint: Bonus lives:
In level one, climb the shelves of the tall dresser in the hall to the right of the bedroom. Jump over the enemy without getting hit to get a bonus life.

Turn off the lights before you leave the room where you have to switch on the lights to get a bonus life.
