The Real Ghostbusters/Stage 9

Once all three Ghostbusters (and Slimer, in the case of the one who had beamed up any of the Green Ghost ghosts) have reappeared upon the screen eight Type 1 enemies will come flying down towards you from the top of the screen, while sticking their tongues out at you; once you have fired a shot at each of them to kill them, they will leave eight ghosts behind (two of which have a Shot Power Up and a Green Ghost powerup inside). Once you have beamed them all up, Slimer will reappear and start circling around your Ghostbuster (if he died after beaming up any of the three previous Green Ghost ghosts, but if he did not, it will not have any effect) - and remember that even though Slimer can block enemy shots, he does not make you invulnerable.

You will then have to walk to the left as two more Type 1 enemies come flying up towards you from the bottom of the screen while sticking their tongues out at you; once you have fired a shot at both of them to kill them, they will leave two more ghosts behind. Once you have beamed both of them up, you shall have to continue walking up over two angry-looking spikes (while they have receded into the ground), as three Type 17 enemies come flying down towards you from the top of the screen - and once you have fired enough shots at each of them to kill them (remember they will change colour from red to peach when close to defeat), they shall leave three more ghosts behind. Once you have beamed them all up, you will have to continue walking up as eight Type 15 enemies emerge from four holes in the ground and start walking towards you while throwing axes at you; once you've fired enough shots at each of them to kill them they shall leave eight more ghosts behind. Once you have beamed them all up, you will have to continue walking up as you come to three rocks - and once you've fired enough shots at the third one to destroy it (not while standing in front of it) it shall leave a tree trunk behind.

You shall then have to continue walking up across the tree trunk, as three Type 14 enemies come walking down towards you from the top of the screen while extending their heads towards you; once you have fired enough shots at each of them to kill them, they will leave three more ghosts behind. Once you have beamed them all up, you will have to continue walking up as you come to a fourth rock - and once you have fired enough shots at it to destroy it (again, not while your Ghostbuster is standing directly in front of it, because his shots shall merely pass over it), it will leave another tree trunk behind.

You will then have to continue walking up across the second tree trunk as four more Type 14 enemies come walking down towards you from the top of the screen while extending their heads towards you; once you've fired enough shots at each of them to kill them, they'll leave four more ghosts behind. Once you have beamed them all up, you will have to continue walking up as two more Type 1 enemies come flying up towards you from the bottom of the screen while sticking their tongues out at you - and once you have fired a shot at both of these to kill them they will leave two more ghosts behind. Once you beam them both up, you must walk to the right and up over a third angry-looking spike (again, while it has receded into the ground), as four Type 4 enemies come walking towards you; once you have fired a shot at each of them to kill them they will leave four more ghosts behind. Once you have beamed them all up, you will have to walk to the left and up as you come to three more rocks - and once you have fired enough shots at the first one to destroy it (once again, not while your Ghostbuster is directly in front of it, for his shots shall pass over it), it shall leave a third tree trunk behind.

You'll then have to continue walking up across the third tree trunk as two Type 20 enemies come walking down towards you from the top of the screen while firing beams in five directions from their scythes at you; once you have fired enough shots at both of these to kill them, they shall leave two more ghosts behind. Once you have beamed both of these up, you will have to continue walking up over eight more angry-looking spikes (once again, while they have receded into the ground) as five more Type 17 enemies come flying down towards you from the top of the screen - and once you have fired enough shots at each of them to kill them, they'll leave five more ghosts behind. Once you have beamed them all up, you will have to continue walking up as two more Type 14 enemies come walking down towards you from the top of the screen while extending their heads towards you; once you have fired enough shots at both of them to kill them they will leave two more ghosts behind. Once you've beamed both of them up, you will have to continue walking up, to the right and up over two more angry-looking spikes (yet again, while they've receded into the ground) as you come to two Type 1 boss enemies and a Type 2 boss enemy (and the game's "boss" theme starts to be heard from the Yamaha YM-2203 and YM-3812 as a result) - and once you've fired enough shots at each of them to kill them the Type 2 boss enemy will explode into eight red atoms (which can still kill the Ghostbusters if they hit them). Once all the atoms have flown off the sides of the screen a key shall appear in front of the double doors; once you collect it the double doors will open up. Once all three Ghostbusters have walked through the double doors, the text "STAGE CLEARED!!" will appear on the screen for a ninth time - and the "Ghost Storage" theme shall now start to be heard from the Yamaha YM-2203 and YM-3812 for a ninth and final time as all three Ghostbusters walk up to it and deposit their beamed-up ghosts into it for the last time. Once they have done so, they shall proceed to the tenth stage.
