My definition of Double Play

In the truest sense of the term, "dual play" or "double play" to me means walking into an arcade, sitting down (or standing) at a machine, and playing both Player 1 and Player2 at the same time. No fancy joypads, or rewired buttons, just a regular game in an arcade cabinet. Obviously the point here is to be able to accomplish this feat in public, without any special preparation. I'll get to this last point in a moment.

Double Play was born in Japanese arcades by fans who were constantly looking for increased challenges during the 1990s. Now given today, inside the United States arcades are pretty rare, and ones that have vertical shooters are even rarer, its understandable that people also attempt this feat through emulation (Mame), consoles, and with dual shock joysticks, remapped buttons, or some other gadgetry. Although this is still a pretty amazing accomplishment, its still not as skilfully performed as on an arcade control panel, which requires a larger amount of hand dexterity ( versus thumb dexterity on something like a dual shock joypad). So my definition of Double Play will pretty much center around what would be possible inside a public arcade in Japan.

Now certain games lend themselves to Double Play easier than others, say for example shooting games that have only two buttons. Some Japanese arcade operators install rapid fire circuits on button C, and some do not. Some arcade PCBs have options to turn on C-Shot (rapid) through dip switches and some do not. Its mostly hit and miss based on the game and arcade operator. Generally if there is an advantage to higher scoring, operators in Japan try to please their patrons by allowing C-Shot or install rapid fire circuits.

Ok given the above setting, and not being allowed to open up or change arcade machines in public, the only other preparation that goes into Double Play may be some tape or toothpick or paper wedge to keep certain buttons held down during the entire run. This is usually to keep your hands from cramping if you constantly need to hammer on a fire button while controlling your ship.

Raiden DX double play sighting in the wild!

Check this out, while eating Pho with my fiancee, I spotted a coffee shop right next door which had what looked like an arcade cocktail table inside. After going in, I was surprised to find a Sega Aero Table with Raiden DX!

This alone was a pretty rare find, but upon closer inspection, I found both P1 and P2 sides had their 3rd button (which is normally autofire on Raiden) stuck down with what looked like a torn up cigarette box jammed into the edge of the button. This was a good indication that someone was probably having a double play run with both ships.

I went back to the coffee shop today to take a pic with my camera, but the buttons were unstuck, making it somewhat difficult to have a dual play run stretching my fingers to the 3rd button of each player. Next time I go, I'll bring a toothpick to jam in there to hold the buttons down.

Double Play or Dual Play?

I'm not exactly sure if the term is "Dual Play" or "Double Play", but the menu option in Raiden III (and most likely in Raiden IV) call it Double Play, but I refer to it as either.
Anyway, Dual Play Shooting will be a side topic for me to document my thoughts and experience playing vertical shooting arcade games (also known as shmups) while controlling both player 1 and player 2 ships at the same time. Even though this technique of playing has been around for over 15 years (since the original Raiden days), it was made much more public/popular by VTF-INO with his Ikaruga replays (see youtube example below).
