Who you gonna call? Not necessarily this game but at least it's better than the NES version.
Ghostbusters was originally released for various platforms in 1984, similar to the NES version it was a port of the same game. Although the NES version is far worse, the SMS version still has a few problems.
It does have its fair share of outstanding graphics and more variety of ghosts, items, and vehicles. The cars are also much easier to avoid. But like the NES version, the Ghostbusters theme plays throughout the entire game except for the endings. The title screen at least has Ghostbusters lyrics. In addition, the game has 3 additional songs for the endings, unlike the NES version, and they're pretty good. But again, like the NES version, it also requires a lot of waiting.
The staircase level, while not as difficult and broken as the NES version can still be a challenge, as the ghosts keep respawning after they're killed, and if you fail three times, you got back to the beginning of the game. However, it doesn't require you to mash buttons to get to the roof. And although you can use your proton packs in the staircase section, the direction of fire is limited.
The level where you have to get past the Stay-Puft Marshmallow Guy is difficult and tedious. If you mess up two times its back to the beginning. Marshmallow Guy also looks much smaller in this section, although he appears to be his regular size on the map screen.
The final battle against Gozer, while more bearable than the NES version, is still frustrating. And for some reason, Gozer is referred to as "Gorza", while the building is referred to as as "The Zuul".
No spook, specter, or haunt will ever be safe again in this game, but then again...
