Trivia / Raiden Fighters

• The original arcade games run at 54 FPS, an extremely odd framerate especially in NTSC territories where TV screens refresh at 60 Hz. (In PAL regions, TV refresh rate is traditionally 50 Hz.) While many arcade games use screens that refresh at slightly under 60 Hz, this is still quirky even by those standards. The Aces Compilation Re-release allows the option to run the games at 60 FPS in addition to the original 54 FPS, but this causes the game to run 1 1/9 times as fast as its arcade counterpart, as the game's timing is based on frames rather than a timer.

• Bad Export for You: Raiden Fighters 2 2000 is easier than Raiden Fighters 2, and the hardware was simpler (i.e. cheaper), sacrificing the sound quality. Why is this a bad export? One would assume that since it was primarily for the Chinese market, the cost needed to be dropped. Ironically, this inferior sound sounds better in MAME, since the better-sounding sound is not yet fully emulated (the intended generally-upbeat techno sounds like hokey hardcore techno instead).
• Dummied Out: Jet. The "penalty zone" track along with a number of graphics, sprite layers, and being able to drop bridges on enemies.
