Could you try following keys?
CACQ33L4: Airplane landing simulator
JEE3V3NE: Vertical scroller action
Y33NQ54S: Wandering in the maze
VKAKV3ZP: Car racing
And you should look for keys yourself.
Both here and in Japanese smileBASIC community, many keys will be exposed and you can find them easily. Of course I know you cannot read Japanese, but you must be able to recognize keys.
