Please help me about the super mario version on gameboy which has a disk inserted to a battery gameboy.

It has a boo, a enemies menu, bowser puzzle and the thing i forgot is the Luigi's world. In this game included on the disk(selected at the main menu) you will enter a world controlled by luigi and has a poisonous mushroom. The game mode is very hard 300% more harder than the ordinary game mode.


Note: This is not the Lost levels of SMB2 which is showing on google. This is because i played this when I was 4-5 yrs old. My mind aches when i want to play this game. Please help me.
