It wasn’t unusual to see lightgun shooters adapted to the 16-bit computers of the late ’80s and early ’90s. However, you didn’t tend to see a lot in the way of lightgun peripherals.
You did, however, see a lot of these games making use of mouse control to simulate aiming a gun. Some of these made use of a clear, obvious mouse cursor, allowing for precise aiming, albeit at the expense of a certain feeling of “authenticity”. Meanwhile, some, like Ocean’s solid adaptation of Taito’s Operation Thunderbolt, provided the interesting twist of making where you were aiming invisible until you fired — much like a “real” lightgun would behave.
While the ST struggles to provide a completely authentic arcade experience — particularly in the sound department, as always — Operation Thunderbolt is actually a pretty solid port, and its unusual aiming mechanics make it surprisingly satisfying and addictive to play, even today.
