Gyruss beats Roc 'N Rope by having not one, but two members who left / were fired from Konami and eventually worked at Capcom. Oh well, I'm sure they didn't work on anything that successful after this game.
Anyway, Gyruss is an omnidirectional tube shooter wherein the player travels from Neptune to Earth. As in most shooters, things will shoot and be shot at.
A set of developer credits are hidden in the ROM, beginning at 0x1E9A in gyrussk.1:
PROGRAMED BY TOSHIO ARIMA CREATIVE BY YOSHIKI OKAMOTO CHARACTER BY HIDEKI OOYAMI SOUND BY MASAHIRO INOUE WE ARE MAKED TIME PILOT
Centuri licensed Gyruss in the U.S., while Konami distributed the game elsewhere.
High Score List
Centuri changed the top four names on the default high score list to their own. Makes sense, right?
Extra Life Settings
For whatever reason, Centuri saw fit to adjust the bonus life settings to make the game more difficult.
|Easy||30,000; 90,000; every 60,000 after||50,000; 120,000; every 70,000 after|
|Hard||40,000; 110,000; every 70,000 after||60,000; 140,000; every 80,000 after|
