This is a text adaptation of an interview that Lucas Milani Santiago took from Vitor Vilela, the engineer who fixed Gradius III. It was a very early game for the SNES. The programmers focused on making an arcade port. Since it was an arcade port, they didn’t optimize the code at all. Because it wasn’t optimized, the game ran on a very low framerate compared to the arcade. The infamous slowdow in present even in the arcade version.
