10:15 - I can STILL feel the dread and anticipation of that damn MARSHMALLOW ALERT 30 years after I played it. The 'B' key [drop ghost bait to attract Mr Stay Puft away] on my C64 got panic-mashed so hard, so often, that it sat 2mm lower than all its plasticy brothers and sisters.
Some tips for others; The hearse is the best choice for a car. The PK Energy Detector, Marshmallow Sensor and Containment System are too expensive and don't help much. Buy the Vacuum, Bait and lots of traps. The Image Intensifier helps but isn't required. Press 'B' to drop Bait when the Marshmallow Man starts to form. Always Vacuum ghosts, it helps keep the city's energy level down. Drive in the center so you can quickly reach ghosts on both sides. Press Space to check your status.
Never used that technique to capture the ghosts... I used to point the guns at each other, wait for the ghost to come in the middle, and then get them closer and closer until the ghost had nowhere to go, then open the trap!
I was only a child in the 80ies but because of C64 and games, I spoke almost fluent english at the age of 10. I am swedish =) These games are pure quality with music that's still are awesome.
I never managed to crack the Marshmallow level years ago. It's interesting to see now how it can be solved. Back in the '90s, most players didn't have access to the Internet for hints or solutions.
Spent my whole youth in the eighties thinking this was just a broken, unfinishable game. Only now, at age of 44, I learn that I had to press the f****ing B!!!! Sometimes the Internet is useful
Traps isn't the only way to earn money. Double ghost vacuumed give 200$ or so. It's, however, not a reliable or efficient way to earn money but more of a tiny "bonus".
At 4:30am, on Monday the 14th of January, 2019, I only now just discovered how to stop the Marshmallow Man (getting the marshmallow sensor and pressing B just as an attack is happening). Over 30 years after playing the game on C64 as a kid have I realised this. I played the game on Sega Master System and completed it. But never on C64. Speaking of which, from memory, I'm pretty sure the Master System version had an extra stage once you got into the building past the Marshmallow Man. It was basically you zapping ghosts as you made your way to the top of the building.
Funny, everyone credits RGB with naming him Slimer but I think it was this game that did that, based on Stantz’s line in the movie. God, do I miss those days!
On the intro screen of you pressed the space bar it would say 'Ghostbusters'. I went throught the entire Ghostbusters song in the intro and played the voice sample at the right spot in the song.
For the fans, these days there is C64 mini you can buy which connects directly on your modern tv. It's a small game box with 64 games already on it. Most of these games are not the 'classics' like this game but you can add most of the classic games through hack downloads on the Internet. So you can play all you C64 classics on your modern TV. Works like a charm
I reached the final stage only once but had no idea what to do. Also didn’t know you could go in from the left. Tried twice from the front, go trampled, got frustrated, never player it seriously again.
Being a Ghostbusters fan, this was one of my favourite C64 games back in the day. Happy to say that I did finish it. I never used the Marshmallow sensor tho, just hovered over the keyboard ready to press "b" when the alert appeared on screen. Having played the same game on a few different consoles now I agree that this is the best version of the game.
Gotta love the little foot shuffle and "Ghostbusters!" after a ghost is capped. I appreciate the notes added in, when I played this as a kid I had no idea what was going on or what anything other than the traps and the vacuum did.
That last laugh made me laugh! What a great game, played this through numerous times. It seemed much more easier to pass marshmallow man from the left! I always tried between the legs. Car number 4 was really fast, it was possible to make lots of money with it. Ghosts gave 300 to 800 bucks compared to how fast you got them after alert. I remember one funny detail - if ghosts on the road came at the same time, they held each other hand while flying over your car!
Used to get to play space invaders whilst this loaded, I think it was a budget company called ricochet that was selling it at the time. Also had knight mare by them
Did anyone take notice the the C64 SID chip was good enough to produce human speech? AKA- the shouted: "Ghostbusters!" NB- Never got through the legs, either!
+John Klumpp I remember it from years back when I was 6. My best friend invited me over to see his cousin's computer, and ghostbusters was one of the games he showed us, and if you got hit by slimmer you could hear a voice say "He slimed me!"
+John Klumpp This was done by using the 'noise channel' and quickly alternating it on of. This in effect created a 1-bit digital audio sample. I think this was a trick that was only used later on in the life of the C64. Amazing sound chip.
I first heard the SID speech effect in a game called 'Tales of the Arabian Nights' That game had a lot of examples of this throughout. It was quite early on as well - about 1983/84?
The problem was, that having speech in the game took up so much memory that almost every game had nothing else happening when speech was being played because it made everything else so choppy (I think Beach Head II is the only exception). The other problem was that Electronic Speech Systems Inc. raised its prices up so high after Impossible Mission became such a huge success that not too many games had speech after this.
actually it works by a flaw in the chips design not the noise channel. Shifting the volume registers cause a controllable pop. By doing it fast enough you can control the intensity. This actually creates a 4th channel. There are actually some game music songs that use this for 4 voices.........the catch being that it can't do anything else so only for the intros because the CPU has to focus exclusively on this.
I never realized that damn vacuum could actually suck up those ghosts on the street! I never bought it because I thought a vacuum cleaner sitting on my hood looked ridiculous.
Hooray, they included the famous 'Marshmallow Sensor' from the movie. Without this ingenious device, they'd never know where the 100ft high death-mascot was.
There isn't much to do in this game, but I loved it anyway, because it had the cool music, speech - and it's Ghostbusters! Ahhh that's from the good old days, when we thought the Americans are the good guys and everything American is really cool.
So you could actually beat this game? :) When I played it as a kid I had no idea what I was doing and could hardly speak english. When the marshmallow man started crushing buildings I would go bankrupt and just start the game all over again :)
Yeah, at first (age 6-8) I'd usually get slimmed and would never prevent Stay Puft from demolishing a building (even remember a time where I ended up crying). When I got a little older (10-11), I'd have my finger ready for that B key, and would ace this game regularly.
Here I thought I was the only one who used the "walk backwards and drag the ghost into the trap" trick. I played this game so much, and kept reusing the same account, and as of the last time I played it I had upwards of a million bucks. I downsized 11 years ago in preparation for a move and selling the old C64 is the one thing I truly regret.
The best version out of the original 8 bit micro releases in the US. Probably the best out of whole lot. On the Mastertronic UK cassette budget re-release, they included a space invaders clone that you played whilst the main game loaded into the C64's RAM.
Oh, that's why someone else said he played Space Invaders while this loaded. I had no idea what he was talking about. Sounded like he had an arcade machine in his room. 😂
Wie schon jemand sagte, nach 25 Jahren weiß ich nun endlich auch, wie man das Spiel richtig zu Ende bringen kann XD Hab damals irgendwann aufgegeben, nachdem mir das Spiel und die Musik zum Hals raushing... jaja, die guten alten Zeiten ;-)
I still remember the first cheat code I ever learned was on this game: Name: Owen. Account number: List. You were given enough money to get all the cool stuff and play for over an hour before having to confront Zuul and Gozer!
I remember playing this on the C64 back in 1986. I would love to own it again. Its nice to watch it here tho. Thanks for uploading. I feel all christmasy now!!
I love how there was no concept of scale in this game with the Marshmallow Man and the size of the buildings at the end. He looked like he may be 30 ft. tall in this game (at the end) as opposed to a couple hundred feet tall.
Watching this brings back many many many fond memories. I lost count of how many times I played this through, taking note of the account number at the end, stacking up the millions lol. A little quibble, you missed out the portable containment unit during the equipment selection, but otherwise a very fullfilling playthrough, thanks!
Never had this one or played it, remember the ads for it and it was one on my wish list. Thanks for uploading - I see it was a while back you did but thanks all the same!
1:06 surprised to see the words pink and slime in one sentence although the the game came out way before ghostbusters 2. Well maybe it’s just coincidence.
I see you have nice technique for catching slimmers. I used to set the team face to face but then I couldn't get them to close to avoid crossing beams.
I could never get under Stay Puft's legs at the end. I never thought of going in through the side instead of between his legs. 😭 You really should've gone back to the store and upgraded your car so that it would go faster.
I had this game for the 64, but I was never able to play it because I had a bad VIC-II chip, where the horizontal scrolling function had one bad bit, and you have one guess to which horizontal position the screen is set to during the entire game 😑
I'd say the ghost vacuum is pretty important to slow the buildup of PK energy, but yes, the marshmallow bait is vital. I +cough+ didn't have the instruction manual when I played this game and thus didn't know how to stop the Stay-Puft Marshmallow Man from wrecking entire city blocks during my game and sending me into the red.
This game was my ultimate favorite, I actually had an account book to keep a score of my bank balance...my favourite car was the station wagon..holds more equipment..
This game is relevant to what is going on during the COVID-19 pandemic. So when the team captures and cures somebody the hospital cheers "Coronabusters!"
Also, who knew that you didn’t have to drive around to the front of every building to go to it on the map. If you were by one that was beneath you on the map all you had to do was pull down on the joystick and press to start driving and you’d be there instantly.
I discoverer a cheat by accident, if i remember correctly you positioned both your men at the left hand of the screen very close together and point your beams in the same direction left-left or right-right, and timed it correctly the ghost would magically disappear and reappear directly above the trap.
When adjusted for inflation, this cost as much or more than Skyrim. And i played the everluvin' shit outta this game. But i was 7 and never got past that marshmallow asshole.
I only ever bought the bait, the vacuum, and then the rest i spent on traps.. I just LOADED up on traps. As a kid, none of the other stuff ever really made sense to me. I would just bust and bust and bust until my traps were full and then go back. Trapping the ghosts was all about timing. I never bothered much with the streams, you just had to time the trap.

Played the shit out of this in the 80’s. Still looks and sounds great thirty years later.
10:15 - I can STILL feel the dread and anticipation of that damn MARSHMALLOW ALERT 30 years after I played it. The 'B' key [drop ghost bait to attract Mr Stay Puft away] on my C64 got panic-mashed so hard, so often, that it sat 2mm lower than all its plasticy brothers and sisters.

lol love it!!
Yes I remember that feeling of anxiety!
Be grateful it doesn't had enough memory to include a stairs level!
Some tips for others;
The hearse is the best choice for a car. The PK Energy Detector, Marshmallow Sensor and Containment System are too expensive and don't help much. Buy the Vacuum, Bait and lots of traps. The Image Intensifier helps but isn't required. Press 'B' to drop Bait when the Marshmallow Man starts to form. Always Vacuum ghosts, it helps keep the city's energy level down. Drive in the center so you can quickly reach ghosts on both sides. Press Space to check your status.
Never used that technique to capture the ghosts... I used to point the guns at each other, wait for the ghost to come in the middle, and then get them closer and closer until the ghost had nowhere to go, then open the trap!
Yeah, I think that was what was intended.
I was only a child in the 80ies but because of C64 and games, I spoke almost fluent english at the age of 10.
I am swedish =)
These games are pure quality with music that's still are awesome.
I never managed to crack the Marshmallow level years ago. It's interesting to see now how it can be solved. Back in the '90s, most players didn't have access to the Internet for hints or solutions.
Spent my whole youth in the eighties thinking this was just a broken, unfinishable game. Only now, at age of 44, I learn that I had to press the f****ing B!!!! Sometimes the Internet is useful
Traps isn't the only way to earn money. Double ghost vacuumed give 200$ or so. It's, however, not a reliable or efficient way to earn money but more of a tiny "bonus".
I really enjoy watching this! So many childhood memories.
another great Actvision game created by the legendary David Pit Fall Crane
At 4:30am, on Monday the 14th of January, 2019, I only now just discovered how to stop the Marshmallow Man (getting the marshmallow sensor and pressing B just as an attack is happening). Over 30 years after playing the game on C64 as a kid have I realised this.
I played the game on Sega Master System and completed it. But never on C64.

Funny, everyone credits RGB with naming him Slimer but I think it was this game that did that, based on Stantz’s line in the movie. God, do I miss those days!
I remember when I first heard the music get to space bar in a voice said "Ghostbusters".. I was amazed!
On the intro screen of you pressed the space bar it would say 'Ghostbusters'. I went throught the entire Ghostbusters song in the intro and played the voice sample at the right spot in the song.
Achievement Unlocked!
I beat this game before it hit the shelves in Canada lol I would still play it now :)
This was my game back in the day. AVGN bashes this game, but countless hours were spent on this semi challenging game.
The first tape game I loaded on my brand new C64 back in the eighties. Nice to see it again.
i never even managed to get past the marshmallow man's leg when i was a kid
That music is just awesome!
A nice little original game for the time, played like a great amusement.
One of many games that really showed off the power of the c64 sid chip
I think I will watch this again instead of the new movie this year and still have a better time!
+matey182 word!
yeah,, good idea
The movie was funny! Sucks 2 b u
PerfectMisconception nah. That's just you being a dick.
Wish I had read this comment yesterday.
This looks like an improvement from the NES version!
The irony is that this is the original game.

Same here pal lol
Plus, you wouldn't earn money catching the ghosts while on the road. Only good thing was that it was the easiest part of the game.
My understanding was you sucked up the ghosts on the road and this kept the city PK energy down thus letting you trap more ghosts and make more cash.
Hooray, they included the famous 'Marshmallow Sensor' from the movie. Without this ingenious device, they'd never know where the 100ft high death-mascot was.
Is that the rectangular box Spengs' was holding on to?
There isn't much to do in this game, but I loved it anyway, because it had the cool music, speech - and it's Ghostbusters!
Ahhh that's from the good old days, when we thought the Americans are the good guys and everything American is really cool.
Yes. Now we have our schools brainwashing kids like you to hate their own country.
Love your avatar! Thought there was a hair on my phone and I was trying to wipe it off!
We are the good guys.
I played this game for literally hours upon hours upon hours, and never did figure out what the hell I was supposed to do, lol
So good to see this great little game one more time!
I would just sing along with the intro for ever
I played this game hundreds of times but only 1 time did i see the big dude in front of the stairs. :(
Damn and the actor who played Egon is dead in real life .. RIP... great game back in the day..
Harold Ramis is his name .RIP
So you could actually beat this game? :)
When I played it as a kid I had no idea what I was doing and could hardly speak english. When the marshmallow man started crushing buildings I would go bankrupt and just start the game all over again :)
Same 😄

Getting all the way to the end then getting squashed by stay puft...possibly 1 of the most annoying deaths on a video game to this day
One of my favorite games when I was a kid
Wie schon jemand sagte, nach 25 Jahren weiß ich nun endlich auch, wie man das Spiel richtig zu Ende bringen kann XD
Hab damals irgendwann aufgegeben, nachdem mir das Spiel und die Musik zum Hals raushing... jaja, die guten alten Zeiten ;-)

omg. we played this game endlessly. thanks for the post
Endlich hab ich nach 30 Jahren das Spiel kapiert. Konnte ja als Kind kein Englisch. Sobald mein Brotkasten wieder läuft, wird gezockt
One of the best movie-games for the C-64!
I love how there was no concept of scale in this game with the Marshmallow Man and the size of the buildings at the end. He looked like he may be 30 ft. tall in this game (at the end) as opposed to a couple hundred feet tall.
My first ever game along with beachhead
early childhood ;_;
10:51 That laugh.
Had to be on your toes to fire the ghost bait whenever Stay Puff came around.
Who are you gonna call? Ghostbusters!
Watching this brings back many many many fond memories. I lost count of how many times I played this through, taking note of the account number at the end, stacking up the millions lol.
A little quibble, you missed out the portable containment unit during the equipment selection, but otherwise a very fullfilling playthrough, thanks!
whoooaaa one of my first computer games in 1985 ish
One of the best games ever for this system!!!
Never had this one or played it, remember the ads for it and it was one on my wish list. Thanks for uploading - I see it was a while back you did but thanks all the same!
GHOSTBUSTERS!!!
Btw, I had the floppy drive for the C-128, and I was the 525th viewer of this video! That's too awesome!
Little did we know at the time that Activision would become the true monster
fun game as a kid..played it alot..dont think I really understood how to finish it though
was going to say same thing. the map bit with the cars etc. no clue. hours spent on it too
1:06 surprised to see the words pink and slime in one sentence although the the game came out way before ghostbusters 2. Well maybe it’s just coincidence.
Great vid of a classic game.............. awesome
Marshmallow Sensor always seemed kind of pointless as you could just drop the bait when he showed up.
Yeah that's why I rarely bought that.
Vacuum too, since no money was earned catching ghosts that way.
I lol everytime I see the 'marshmallow man'..
Looks like an angry chef doing jumping Jack's lolol
Best version of the David Crane game!!!
wonder if AVGN knows about this
I see you have nice technique for catching slimmers. I used to set the team face to face but then I couldn't get them to close to avoid crossing beams.
07:58 when the 👻 hits the man he said he slimmed me
Msiba Jones he definitely said slimed i.e. "he put slime on me" and not "he made me slimmer" ;)
I could never get under Stay Puft's legs at the end. I never thought of going in through the side instead of between his legs. 😭 You really should've gone back to the store and upgraded your car so that it would go faster.
I had this game for the 64, but I was never able to play it because I had a bad VIC-II chip, where the horizontal scrolling function had one bad bit, and you have one guess to which horizontal position the screen is set to during the entire game 😑
He slimed me, lmao awesome, brings back some memories
Take the cheapest car, mallow bait, and a couple of traps. Thats all you need. The less you buy, the less money you have to make to break even.
I'd say the ghost vacuum is pretty important to slow the buildup of PK energy, but yes, the marshmallow bait is vital.
I +cough+ didn't have the instruction manual when I played this game and thus didn't know how to stop the Stay-Puft Marshmallow Man from wrecking entire city blocks during my game and sending me into the red.
I never bought the vacuum, since it didn't seem to affect the game at all- no $$, no PK, no nothing.
Getting past the Mashmallow Man at the end was so frustrating! I did it off of sheer luck. He was a bastid!
I was today years old when I learned you could sneak in from the side like that - I always tried to get in between his legs and got squashed.
Ja wie geil ist das denn? Das Spiel hatte ich auch. Hat viel spaß gemacht damals.
This game was my ultimate favorite, I actually had an account book to keep a score of my bank balance...my favourite car was the station wagon..holds more equipment..
He slimed me!
This game is relevant to what is going on during the COVID-19 pandemic. So when the team captures and cures somebody the hospital cheers "Coronabusters!"
I think I recall we heard that if you managed to mess up catching a ghost, the slimer would fly down and knock one of the men down..." he slimed me"
The video shows that.
I loved this game as a kid but dear god did it stress me out like nothing.
I had to take a 3 day break between sessions.
Also, who knew that you didn’t have to drive around to the front of every building to go to it on the map. If you were by one that was beneath you on the map all you had to do was pull down on the joystick and press to start driving and you’d be there instantly.
Oh ja, das ist richtig gut.
8:02 what's happening here with Marshmallow man?
The player used the ghost bait (by pressing B on the keyboard) to attract the marshmallow man and prevent it from causing damage to the city.
Name ANDY account number 777, that's the infinite money cheat. Also works on emulators.
+Demonmixer I couldn't even get to ZUUL with the code .
mrconancat
Me neither. C64 games were really hard.
I used Owen, account number List
Che spettacolo c8 ho giocato settimana scorsa.. C64 History
I discoverer a cheat by accident, if i remember correctly you positioned both your men at the left hand of the screen very close together and point your beams in the same direction left-left or right-right, and timed it correctly the ghost would magically disappear and reappear directly above the trap.
awesome 9.99 quid - activision - black library case - bouncing ball lyrics and music - yeah this was great
Silimar GFX to Atari XL/XE but the music is out - like Spectrum.
Amazing..!!!
When adjusted for inflation, this cost as much or more than Skyrim. And i played the everluvin' shit outta this game. But i was 7 and never got past that marshmallow asshole.
Woooow ci giocavo al SEGA Mega Drive .... 1993....ma questo è 1988 ?
I only ever bought the bait, the vacuum, and then the rest i spent on traps.. I just LOADED up on traps. As a kid, none of the other stuff ever really made sense to me. I would just bust and bust and bust until my traps were full and then go back. Trapping the ghosts was all about timing. I never bothered much with the streams, you just had to time the trap.
zuul started to go crazy after a bit in this game, a thousand ghost appear on the highways..amstrad version was great.
We have the commodore but i haven't used it (EVER)
Dont cross the streams!
That was featured in this game too (if your streams touched). Leaving the two Busters flat on their backs (or packs).
Great movie adaption!
