Sidearms 

A coin-op game released by Capcom/Romstar in 1986. The full title was Sidearms Hyperdyne in the U.S. and Hyperdyne Sidearms in Japan. Sidearms was a very underated and somewhat rare shooter/shmup with a Robo-Tech type theme. The game featured both 1 and 2 player simultaneous action, horizontal and vertical scrolling, several stages ranging from moderate to downright difficult, challenging and sometimes huge bosses, a special power-up that unlocked a dual mecha transformation and other bonus features. The game was ported mostly to computers such as the Atari ST, and Commodore 64 as well as the PC-Engine/TurboGrafx-16 and also Sony's PSP in a Capcom compilation. Sidearms was the second game in a series known as "Jetpack Hero" which started with Section-Z and ended with Forgotten Worlds. They are related only in that they have a similar layout and gameplay; each game in the series has it's own storyline.

"I can't believe how accurate this port of Sidearms is and the sound is better than the arcade verion!!"

Sidearm Distance (Frisbee) 

Sidearm Frisbee, a Frisbee throwing technique, placing the disc between the thumb and first two fingers then throwing from the side. (similar to a sidearm baseball throw)

Ken Westerfield's sidearm distance record of 552 feet, with a 119 gram World Class Model Frisbee, Boulder Colorado 1978, and Victor Malafronte's, 538 feet also with a 119 gram Frisbee, not only have the longest sidearm throws of all time but are the best sidearm throwers of all time.

At a North American Series (NAS) Frisbee tournament in Dallas Texas, Westerfield became a member of the "400 club" with a prelim distance sidearm throw, and won the event with a throw of 378 feet, using a 119-gram World Class Model Frisbee. Only two competitors have officially ever thrown over 400 feet in competition with a 119-gram Frisbee (Lightweight disc by today's standard).

1978, in Boulder, Colorado, while doing a distance throwing demonstration at a North American Series (NAS) Event, Westerfield threw a sidearm 119-gram World Class Model Frisbee, 552 feet, shattering the official world distance record of 412 feet

Tournament officials marked and measured the throw at 552 feet. Since the introduction of heavy weight, sharp edge disc, the world record is now over 800 feet. However Westerfield's 552 feet is still the record for the sidearm throw

Sidearm Distance (Frisbee) is covered in several Wikipedia Articles

Sidearm 

n. A paradox of Einsteinian proportion, that which is at the same time bad-ass and refined. That which saves brown babies and prepares homemade pasta dough. That which is truly hoss and yet truly gentile. A man of amazing proportion and ridiculous excess. A man of this age and all others.

The sidearm feverishly prepared his fifth culinary masterpiece while simultaneously smoking a pipe and saving a brown village.
