The Green Hill Circuit is located in the top-left of the track selection screen, so if you are using MAME to play the game, you will not be able to select it if you have not calibrated the steering by pressing "9" and "F2"; its timer will also start out at 70 seconds.
Once the traffic light on the right side of the screen has counted down from 3 to 0 and you've stepped on the gas pedal in order to accelerate your bike, you will pass under a bridge (for this very circuit), then pass two billboards with an arrow pointing to the north-east on the left side of the track and a television camera on that right side of the track; you will then have to turn to the right, as you pass thirty-two trees, four bales of hay, three black-and-yellow chevrons pointing to the right, a pickup truck with a group of spectators gathered around it, two fast-food stalls, another pickup truck with another group of spectators gathered around it, four more bales of hay and another television camera on the left side of the track, then turn to the left as you pass a third billboard with an arrow pointing to the north-west on the right side of the track, and thirty-six more trees on both sides of that track. Once you've done so, you will have to turn to the right, as you pass a fourth billboard with an arrow pointing to the north-east on the left side of the track, forty-one more trees on both sides of the track and two more bales of hay on the left side of the track, then turn to the left as you pass a fifth billboard with an arrow pointing to the north-west, eight more trees and three grandstands on the right side of the track as well as a third television camera on the left side of the track - and once you've done it, you will have to turn to the left again as you pass a sixth billboard with an arrow pointing to the north-west, two more bales of hay, three more grandstands and a seventh billboard for Casio upon the right side of the track then turn to the right as you pass four more bales of hay and a fourth television camera upon the right side of the track as well as ninety more trees on both sides of the track and an eighth billboard with an arrow pointing to the north-east on the left side of the track. Once you have done so you will have to turn to the right as you pass two more bales of hay, two more billboards (the ninth is for Bridgestone, and the tenth has the arrow pointing to the curved north) on the left side of the track as well as three more grandstands on the right side of the track and forty-one more trees on both sides of the track, then turn to the left as you pass four more bales of hay on both sides of the track and an eleventh billboard with an arrow pointing in the northeast on the left side of the track, as well as five barriers with five more groups of spectators gathered behind them and twenty more trees upon the right side of the track; once you have done so you'll have to turn to the right as you pass three more black-and-yellow chevrons pointing to the right and three more grandstands on the left side of the track, as well as five more (bent-looking) trees on the right side of the track and three more black-and-yellow chevrons pointing to the right on the left side of the track. You'll now have to turn to the left as you pass what are a fifth television camera, two more bales of hay and three more grandstands on that left side of the track, as well as a twelfth billboard with an arrow pointing to the north-west and three more trees on that right side of the track and a sixth television camera on the left side of the track - and once you have done so you will pass two more bales of hay on the right side of the track and three more grandstands on the left side of the track before passing under another bridge for Dunlop, then pass a lamppost and a seventh television camera on the right side of the track as well as a thirteenth billboard for Shoei on the left side of the track and a second lamppost on the right side of the track, before passing under another bridge for this very circuit. You'll now pass two more lampposts on the right side of the track, three more grandstands on the left side of the track and two enclosed grandstands upon the right side of the track before completing a full lap of it; the text of "LAP TIME X'XX'XX'. TIME EXTEND." (X'XX'XX' being your lap time) will then appear on screen, and you will receive 40 extra seconds to complete another lap of the track. Once you have completed between three and six laps of this track (as in the original, it depends on what the arcade owner has set that "LAP" setting in the options menu to), the text of "RESULT" will appear on the screen with your position (1st-8th) below it, and your fastest lap time and distance travelled in metres will then be displayed below that - and, if your total time was lower than 3'12'20', the game will go into "best-time" mode, so you should enter your name on this track's "best-time" table with pride. Once you have done so, the game will go back into attract mode; it is also worth noting that unlike in the original game, the sky will not become darker after every completed lap of this track, as it will remain in daylight for the duration.
