Original title screen for Sinistar, now re-inserted into the game during the reverse-engineering project.

This is an article by SynaMax about reverse-engineering the arcade classic Sinistar. Sinistar is one of the most technically-impressive arcade games of the 1980’s, and one of the first to use voice sampling. Using MAME and 6809 assembler tools, he took the entire game apart, and put it all back together better than ever. He even discovered the origins of the famous ‘Sinistar roar’ sound effect.

He was also able to restore the original title screen from the game (see picture), found in the 1982 prototype.
