>>> TRIVIA
----------
This game is known in Japan as 'Astro Flash'.
This game is not based on The Transformer toys by Takara and Hasbro, which were very popular at the time. The name change from 'Astro Flash' to 'Transformer' was probably an attempt to cash in on the popularity of The Transformers.
This game is a port from an original game created and released in 1985 on the Sega Master System.
