gottlieb haunted house pinball machine no multiball

Ok, just a little fyi, gottlieb haunted house is not a multiball machine. Can you believe that! Wacky!

Any who just for shits and giggles, I am contemplating a few angles for adding multiball.
There is 1 out hole on main playfield.
I think a 2nd on the lower playfield. Well it looks like there is supposed to be, but some one put a target there instead on mine cuz they needed a quick fix? I dunno

Few things, using ball return trough etc off a mars god of war, or black hole etc.

If now one can hack the code, I would probably just use the eprom from another multiball system 80 machine. May have to swap some switch/coil driver baord wires to make sure the right switch trips the correct coils etc, and just use whichever eprom seems to match hanuted house the best in turms of when whic sounds are played... etc.

Hacking the original rom may bebest.

Oh and just a little fyi
The comparison of haunted house and blackhole isn't all its cracked up to be, aside from the lower playfield, they are no more simialr then any other system 80 games, maybe less lol!
Any one heard of anything like this b4?
Think and discuss
 
Sounds a bit like a pipe dream to me, but If you try this, take lots of pics and document the process; I'll be interested to see how it turns out.
 
I think it would be tough to do.....you need to change the ball trough, and would need to fabricate something for the lower level. If two balls go down to lower level, and drain, you would have major issues. You would have to have a gate or similar mechanism to the lower playfield in Black Hole. I'm sure that there are other mechnical issues that would need to be addressed, but the whole other issue is the software. You would need to re-write or modify the original code....big time.

i am unsure what you mean when you say "if 2 balls go down stairs and drain you will have major issues"
in haunted house when a ball drains it just goes back up its not shooing up to actually drain
if i can not get some one to mod the eprom software im just gonna use the software eprom from another system 80 game that has multiball
 
I wouldn't do it unless you have a horrible beater of a machine. Don't hack up a nice HH to add something that the game wasn't designed around.

I'll save you a bunch of pain and just tell you this won't work. It could technically work but it's totally impractical and will be all but impossible to make it play even half decent.

Learn to like it or sell the game. That's my advice.

I agree 100%. If the game's even remotely nice, just leave it as the pinball gods intended. ;)

If the 2 balls are in the basement, and drain together at the same time in basement, the upkicker would have to be mofified to only allow one ball to be attempted to be kicked up at a time.

I promise I won't hack to shit a good games and make it horrible guys. Heh

Im am just trying to document the attempt, in its entirety b4 messing with the machine.

I believe the basement up kicker may actually be a non issue, im not sure how familar you guyd are with the machine though. So I will just say the haunted house upkicker is basically a captive hole on steroids.
It kinda only does 1 ball at a time automatically.
Any ways just some thoughts...
 
Isn't it possible to rewrite the code on the NiWumpf boards? That might be an easy way to go about it (albeit expensive).

The problem is the second ball can hit the first with enough force to either (1) bounce over it, or (2) knock it out of the hole. Depending on the kicker direction, there's also a good chance the a ball resting against it will alter the exit velocity of the ball, potentially causing it to fail to return.

Altering the code from the rom will be pretty much impossible unless you're a programmer with deep understanding of assembler, and the Chips used in that era. Modern x86 assembler is rather different from a lot of processing chips used in early SS pins, so that segments the already incredibly slim population of assembler programmers.

Rewriting the code from scratch is also a mess, since you will need to figure out how the MPU communicates with the various components of the system. While this is PROBABLY documented, rewriting it all by hand would probably take years.

Swapping out the MPU from a MB game such as black hole also presents the major issue of part mismatch, bulb location differences, and the general problem of the whole damn PF being different. You can't just copy and paste sections from one rom to another, it's not that simple.

Swapping the MPU out for a small computer, and writing the code in a higher level language is possible, and would save time on programming, but I doubt anyone's written code to interface with gottlieb lamp drivers, solenoid drivers, etc. so you'd need to write that yourself. Also you'd need to program in all of the rules, and build an interface from the PC to the various system boards.

My FG lacks multiball, so I understand your situation. Trust me, the idea of expanding the kicker to support 3 balls did cross my mind at some point. A quick dirty code hack here and some alterations there... seemed easy enough at first. But once you start to seriously consider it, the amount of work is enormous. The game plays just fine with a single ball, and it's quite fun. So why try to "improve" upon it? The mfg felt it didn't need MB, and the tech was available at the time. Perhaps they left it off intentionally, because it didn't play well.

thank you sir that's another good option to keep in mind as well.

Pascal is also releasing a system 80 board set. If anyone could do multiball on Haunted House it would be him. I have no doubt that he's already been asked about it. Might be worth sending him an email.
