Are you a bad enough dude to
The Real Ghostbusters is the only game where you use an unlicensed nuclear accelerator to destroy floor blocks to find stars to get a key to exit the level. Phew.
We ain't afraid of no blocks!
The Real Ghostbusters/Garfield/Mickey Mouse IV's entire premise is also directly stolen from the Commodore Amiga/Commodore 64 game, P.P. Hammer and his Pneumatic Weapon, featuring simplified sprites and near-identical level designs. According to the developer of P.P. Hammer; Gunner Lieder, the port is entirely unauthorized by Kemco. 
More regional differences.
Kid Klown in Krazy Floor Blocks
The Real Ghostbusters was originally a Mickey Mouse game, which became a Garfield game in Europe and a Ghostbusters game (with extra levels) in America...but apparently, Kemco had other plans for the game.
The NES game released in North America as Kid Klown in Night Mayor World was released as Mickey Mouse III: Yume Fuusen in Japan, and judging by these tiles The Real Ghostbusters was also going to be a Kid Klown game.
Present at 0xE570 are graphics for a sequence with Kid Klown and Princess Honey...
...Plus graphics for an ending sequence at 0x10A92! A mockup can be seen below:
The frames seem to indicate that Honey would run towards Kid Klown and they'd hold hands in the final frame. D'aaaaaaaaaaaww.
The title screen was appropriately changed for each region.
The introduction sequence was slightly changed. The big difference (aside from that Mickey loses Minnie and Garfield loses Odie before falling into a pit) is that Mickey and Garfield find a laser gun at the bottom of the pit, but Peter Venkman does not (since he has his proton pack and all).
The passwords were also changed to account for Nintendo's password censorship. The Real Ghostbusters and Garfield Labyrinth use the same passwords, while Mickey Mouse IV uses different passwords.
There are also numerous sprite changes between the games, aside from the stage-clear screen being changed to display the proper character.
The extra life icon is different between games: Mickey eats cheese, Garfield drinks coffee, and Venkman just picks up an icon of his face.
Garfield and Venkman can lay bombs that will blow up any enemy that walks into it. Maybe that was too violent for Disney, so Mickey lays down wands that make the enemy magically disappear in a puff of smoke. Same effect.
Of course, the Ghostbusters game alone uses the Ghostbusters theme song for most of the stages.
There's a bunch of enemy sprite changes as well. Some versions reuse sprites for enemies that behave differently.
