I suppose there could be a calibration of sorts to find each switch… You’re right, though, the current hardware doesn’t make that feasable.
That’s is right. I did not think of that. More reason to celebrate having the Claw back in.
It is a pseudo-random algorithm. Used for general purposes.
First digits 2-7. Then each digit 1-9. Back to back 5.7M is 1/486 chance (with true random).
Maybe Odd change, being random, should have been sub 1M with the perspective of TZ scoring. But, nevermind. I really like Odd change. Fabulous idea and execution.
Huh, neat! I want to figure out what triggers what.
Oh crap, I might take you up on that if my crew decides to stay for a bit. 
I was met with some confusion over the video mode rules, factory and mod, in Junk Yard. And it is. Confusing. Multiple routes to the heavily over exposured video mode(s), which inspired the mod in the first place. This is the compromise at which it has been toned down.
A factory (v1.2) Junk Yard, this is how the Dog video modes can be started.
-
Magic bus award.
-
Spell DOG -> Make the shot again.
2b) Same as 2) but via the sneak-in on soft left ramp balls. -
Assemble the Toaster gun -> Make the DOG shot.
-
Spot DOG plunge award. Short cut to 2).
-
will also switch the Dog video mode from Run from Spike to Save the girl for rest of game.
Software mod.
- Removed.
- Will switch to bonus-x +1 only (and permanent ball return to the right flipper), if a Dog video mode already played on current ball.
2b) As 2). - Same as factory. And once done, it will apply the same diverter rule as 2).
- Same as factory. Will always lower the diverter and enable video mode.
Playing Outer space wizard mode will reset 2) and allow for a video mode to be started.
So, generally one Dog video mode per ball-in-play. Options for additional ones…
- / 2b), after the wizard mode. A fair reach. Not every game though.
- Common. But only once per game.
- Rare to get and to acquire. Let alone after a Ball recycled.
Note, the additional Time machine/Saucer attack video mode is not mixed into all this.

I’m looking to add Taxi and Getaway competition Roms to my games. I have no way to burn these, is there anyone out there who does or know who is able to burn these. Thanks in advance for any assistance. Dan
Are there lists somewhere of all the alternative ROMs that have been coded? A search didn’t reveal anything, just posts like this on Tilt, Pinside & retailers.
Nope, and there are a couple other places as well, like RGP and pinhacks (now closed to new members) - and there are literally hundreds of variations of just homebrew type mods for tournament, or rules changes/tweaks, bugfixes. I used to submit them to IPDB but they aren’t keen on hacked versions (although they have several for lots of games.)
The issue I think is too many hacks with too little documentation - you get someone putting it in a game and it’s marked just u2/u6 - you’ve no idea where that came from, was it official, was it beta test, etc. (especially for older games).
Maybe I’ll start a list of just ones I know about/wrote. Will stick it on a website somewhere if/when it gets done. I guess I’d have to post checksums of the roms so people can compare and see if they have that version as well… I don’t actually have most of the roms though so I’ll have to hunt them down too.
pinmame actually lists a lot of variants as they’ve been ‘bronzed’ into there, although I question where they got some of the info, clearly some of it was truly a beta test version.
Anything no matter how quick and dirty would be greatly appreciated.
Given what you are saying maybe PAPA could add a list of ROMs they approve in their directors’ guide?
https://sites.google.com/site/allentownpinball/tournament-rom-mods
List is a work in progress as new variants are discovered/found/written.
Includes other rom mods as well, like free play, no battery required, etc.
I will iterate here as well as on that page that I DO NOT have most of the roms. It is merely a listing I have found/perused on the web (a lot of the current listings with the checksums were posted here, on tilt forums.)

Absolutely brilliant, greatly appreciated! Thank you. I will be downloading some of these.
I notice this in the list: Bally (classic -17 and -35 boardsets)
Details: No “tilt through” players. (Classic stern style)
I don’t know how many games fall under this category, but I would hope as many as possible. Is this an easy mod?
I forget who was beta testing them… basically any game from 1976-1985, until they went to the 6803 boardset. Those could probably be done as well at some point.
I know you can ‘fool’ the classic stern tilt-through if you have a fast spinner or something registering, it will process that before the tilt. That’s probably why IFPA just does the definitely working skip players 2 and 4 (which also neatly excises the problem on an eight ball deluxe with players 2 and 4 getting extra bonus without a bugfixed rom in there…)
Strictly speaking of non-factory mods. There are also the 7-digit and the (combined with) free play Bally ones. Maybe it is wise to keep those on a seperate list to avoid confusion.
There are also the semi official Williams ones, that are long standard. Cirqus Voltaire, Twilight Zone, …? And the not so definitive White Water one.
I kind of like the one stop shopping list - I think I’ll add a ‘type’ field (i.e., tournament, bugfix, 7 digit, etc)
I’ll have to do some research on the official/semi official williams ones.
You’d think I’d remember the 7 digit ones since I helped beta test some of them (and wrote a few…)
I am actually thinking about Pinburgh which will use 4 player games. How hard is this to install? @PAPA_Doug
It’s just a rom swap, and in most cases, just the OS rom.
This is great. Also serves as a pretty decent quick list of known issues that might affect tournament games. Huge thumbs up. Hope you can maintain this 
Maybe some more details on the actual bugs would help? Like for example on Dr Who it just mentions there is a tilt bug, but not how the bug affects play?
just curious what patch gui you are using for XD3 extension files the one I have doesn’t recognize that extension
I don’t use a GUI, just cmd with xdelta3-3.1.0-x86_64.exe" under cmd. Simple command, xdelta3-3.1.0-x86_64.exe -d -vfs “ROM.ROM” “PATCH.xd3” “Patched Game.rom” then checksum with http://onlinemd5.com/
