The Duel: Test Drive II Trivia (Genesis)
Commodore 64 versionThe Commodore 64 version has a better frame rate when played on a Commodore 128, because it switches the processor to 2 MHz mode while the TV's or monitor's electron beam is off-screen. (The VIC chip can't handle a 2 MHz clock frequency, so it would show garbage on the screen.)
Version differencesIn the DOS version there are only two cars available; a Ferrari F40 and a Porsche 959. The SNES and Genesis versions also include a Lamborghini Diablo.
