| history | Asterock (c) 1979 Sidam. A single player takes control of a ship trapped in the middle of an asteroid field. A number of large, slow-moving asteroids drift randomly around the play area and must be shot by the player. When shot, the asteroids will break into a number of smaller pieces which must also be shot until eventually, all of the asteroids and fragments will be destroyed and the next wave begins. As well as the ever-present asteroids, alien saucers also make a regular appearance. These move diagonally around the screen firing at the player's ship and must be quickly destroyed. - TECHNICAL - Main CPU : M6502 (@ 1.512 Mhz) Sound Chips : Discrete Screen orientation : Horizontal Video resolution : 256 x 231 pixels Screen refresh : 60.00 Hz Palette colors : 32768 Players : 2 Control : 8-way joystick Buttons : 3 - TRIVIA - This game is an Italian bootleg of "Asteroids". The official Italian distributor of Atari Arcades, f.lli Bertolino s.r.l., moved a legal attack against Sidam, and won. Many code fragments stored in ROM of Asterock, Missile Storm and other Sidam clones was identical to those contained in Atari originals' memory. Sidam changed the coin accept and sound routines, to get rid of copyrighted Atari POKEY chip. Sidam called this a 'coincidence'; moreover, the Italian legislation did not mention directly the computer programs as copyrighted materials like songs and books. However, the court sentenced about the 'intellectual property' of programs - this was an important sentence in Italian legal history - and Sidam was convicted of copyright violation. - SCORING - Large Asteroids : 20 points. Medium Asteroids : 50 points. Small Asteroids : 100 points. Large Saucer : 200 points. Small Saucer : 1000 points. - TIPS AND TRICKS - * When you start the game, your spaceship will be in the middle of the screen. Heading toward your ship will be anywhere from 4 to 6 large asteroids. Your job is to blast those rocks. However, when you blast them, they break up into 2 medium rocks. Blasting a medium rock gives you 2 small rocks. In addition, you have to contend with large and small saucers. On the first few screens, you can sit in the middle and blast rocks to your hearts content. There isn't that much danger since the large saucer doesn't track and only fires random shots. Keep in mind a couple of things when shooting : 1) You can have 4 shots on the screen at any one time. This is useful for when you are blasting rocks at close range. You can pretty much drill them to dust. 2) Your shots 'wrap around' the screen. This means any shot that goes past the edge of the screen will reappear on the opposite side traveling the same direction. The saucers also have 'wrap around' shots. * After 10,000 points, the small saucer becomes a permanent part of the game. You can no longer sit in one place since the small saucer is able to track your ship and take you out with the first or second shot. * Use hyperspace only in very desperate situations. Something like having 4 asteroids coming at you at once, and there is nowhere to escape would be a good reason. 8 times out of 10, hyperspace will either put your ship in danger or when you appear somewhere else, your ship will blow up. * Although there is danger from the rocks and saucers, you can also be a danger to yourself. Use the thrust carefully or you will find yourself careening out of control on the screen. Some players get really good, however, moving around and shooting. * For those desired high scores, you can use the hunting trick. It goes something like this : 1) After 10,000 points, the small saucers appear. They are worth 1000 points apiece. First, blast every rock until you have only one small rock left. 2) Go sit in the upper left or right corner of the game screen. 3) If the small saucer appears from the side you are on, then you can blast it before it gets off a shot. If it appears on the opposite side, use the shot 'wrap around' to take care of it. Some people have done this for hours on end and racked up scores in the millions. Of course, it takes a long time at 1000 points a pop. 4) Also keep in mind that the small saucer can wrap shots so you may have to move out of danger. - SOURCES - Game's rom.
