Back to the Future Part III (Sega Master System)

Play through the movie in four three completely different levels! If "Mad Dog" Tannen's boys don't get you, the punishing and unrelentingly-hard gameplay will!

Level Skip
Press Start to pause the game, then hold I and press Up, Down, Left, Right. If done correctly, you'll skip to the next level automatically. Unlike the Genesis version, entering the code in the final level will go back to the first level, rather than the ending.

Developer Credit
The following text can be found at in the ROM (spaces have been added for clarity): (C)1991 PROBE SOFTWARE LTD BY A.R.LILL D3-06/03-KBS-001

"A.R. Lill" is an alias of Antony Hartley, who worked at Probe Software at the time and specialized in porting games to other platforms. He's not mentioned in the credits shown on the title screen, but at least he made sure someone would find out about it! ... 22 years later.

The final line may be some sort of internal product code.
