Ghostbusters II hack

Recommended Posts

I used to play this game on my C64 and was surprised to find out several years back that it was ported to the 2600. I never enjoyed this one as much as the first (that goes for game and movie) but I must say that the 2600 version seemed really rushed. Considering that the first game was pretty decent on the 2600, this one's lackluster graphics (and lack of the final museum invasion screen- even in a watered down form) was a downer.

 

I took Thomas Jentasch's NTSC ROM of GB II and attempted to make it look more like its computer counterparts. Using the following youtube vids as reference (my C64 is long gone), I resculpted the following on the Van Horne scene...

 

 

Stantz is no longer wearing a hat. He is also reshaped a bit. If anyone wants to take a shot at recoloring him, be my guest.

 

The vertically rising ghost was revised to look more like the computer version (instead of a Charlie Brown "sheet ghost")

 

In the status screen, I narrowed the cable strength graphic. I also redisgned the bomb icon so it didn't look so much like the particle thrower icon.

 

I changed the "pitchfork" (which was supposed to be a long arm reaching out) to a simple profile style ghost.

 

 

Future corrections: I want to change the "courage potion" to look more like a beaker. I really dislike the sawing hand so I may reshape it.

 

The font may be redone to look like the computer version.

 

I need to play King Atari's Easier version to get to the Statue of Liberty sequence.

 

Feel free as always to bend, fold, and mutilate.

Hey this looks great. Its still the hardest game I have ever played! I just cant seem to swing to the pieces. Still working on it? Any chance you can throw a easy difficulty option for me?!?

Hiya Jack- I just started up on this again. I've shortened the outcroppings on the Van Horne a bit to make the Libby phase easier to get to.

 

I managed to change a few ghosts and make Stantz's costume the color I want but am having a terrible time finding the color of the walls (want to get rid of green and change them to brick red) and whatever that little green line over Stantz's head is supposed to be I want to use as his hair. Been looking and can't find 'em. Can anyone help?

Here you go.  I didn't check to see if there are any other references that need changed, but from the 20 seconds I last when I play, the wall color is at offset 0x3510 and the player hair is at 0x3578.

That’s what I’ve always wanted or just another game variation that would allow you to go directly to level 2 “Broadway,” kind of like how Mash lets you skip to the operation level.  
 

the broadway level is actually fun although still way to hard.

Chewy, check out this hack from Atariage hack page.  It makes it much easier to get to Broadway.

I’ve been playing on the Retron 77 and using the save feature I can get pretty far.  That broadway level is pretty difficult but fun.  
 

I’m thinking Broadway would work better as a side scrolling space invaders game.  It sure is pretty with that Activision sunset.

OK finally some time for a few more tweaks...

 

Re-did the cable meter so it looks like a cable. Also changed all the ghosts again. Not much to work with there.

 

It is looking a bit better although the game still is pretty meh.

 

I guess the only other changes I would like to make are the ghosts in level 2 (and that's easy) and colors of the torch and Libby's hand. The flame is fine but I want the hand and torch to be authentic pale green colors and I would love to reshape the hand so it doesn't look like a hamburger bun. I can find the torch and given time the colors for it, but I'm not sure about that hand...
