Is there a link that can be provided to the lab door mod? I feel like this game will never gain any new runners due to the obscurity of this Mod.

Hate to bump my own thread, but can anyone please provide a link to this mod? I would really like to try some runs on this game but only 3 people seem to be able too. If made available more people could run this great game.

Seems like the sole moderator/series moderator El-Nino has been inactive on this website for about a month. His website/Twitch/Youtube also seems like he's heavily inactive on. So no reliable way to contact him. Would suggest following this thread and asking to become moderator of this game/series. Sorry you haven't gotten the information you wanted and hopefully it helps.

This thread is specifically for moderation requests and changes for already existing leaderboards. Please link to the game to help facilitate requests.

Requesting games/series not yet on the site: Use the form here. (https://www.speedrun.com/requestgame)

Please keep in mind that using this thread is a last resort, in case the current moderators are not responding or refusing your help without justification. You should always start by asking the Super mods of a game/series as they are also able to add mods. Best way to contact game mods is probably through Twitter for now. Also try the game forums, many users get notifications when threads are created for games they follow.

Moderator inactivity doesn't apply until around 3 weeks, depending on other circumstances, and it is expected that you try to contact them (exceptions may be made if they have been offline ~3+ months.)

An admin or full mod will respond to your post when they review it; if there is no response, it hasn't been reviewed yet.

Hey there! Sorry, it has been a long time since I've been able to login, so I didn't see your message sitting here. I am sorry for the frustration of having to wait for a response.

Quickly: you likely are playing the "lab door mod" already 🙂 :) 🙂

This simply means that the game has had the copy protection scheme removed.

For the DosBox version, this is the version you will likely have in your collection. For the ScummVM version, no matter what files you give ScummVM (protected or "deprotected") the ScummVM engine will apply this "Lab Door Mod"

How to tell if you have it? Head up to the 2nd floor and interact with the Steel Security Door at the top of the steps. Open it up. If you can enter any code into the code entry screen and it works, you have the "Lab Door Mod." In the ScummVM version the door will be already open.

Now, why is this the "Lab Door Mod"? -- Well, in the PC version, a copy-protected game will require you to enter in a specific code to open the Inner Lab Door. This code is controlled by the high score on Meteor Mess. In the NES version, you can enter 0000. But in the PC version ,if you try 0000. it won't work. However, when the game has the copy protection removed, any code will work for the inner lab door. "0000", "0001" ... any code!

If you want the specifics, feel free to ask, but in a nutshell...just play and get that World Record 🙂

As for the specifics....

In the PC version, the game chooses a few random codes for Edna's phone number, the Meteor Police number, and Edna's safe combination. It's not truly random -- the game just chooses one 4 digit code from a set of a few preset codes. That's why you can just try out a few codes for each of these and eventually hit the right number.

However, for the inner lab, it doesn't actually set the lab code in memory until Fred plays Meteor Mess. When the game starts out, the lab code in memory is set to 4 values that you will never be able to enter with the code entry screen. It would be nice if they set it to "0000", but no 🙂

After Fred plays Meteor Mess, the lab code in memory is set to the 4 digits that are in his high score.

But, when the copy protection scheme is removed, not only does it allow you to enter in the code for the copy protection door (Steel Security Door at the top of the steps on the 2nd floor), it also allows you to enter in any numbers into the Inner Lab Door!

If you have more questions, feel free to ask here, and if you stream your attempts live please let me know, I'd love to check it out.

Take care,
Matt

And what if lab door mod doesn't work on ScummVM? Because my run ended when I got to lab door but nothing worked (except I assume whatever the Meteor Mess HS was, which Fred never got to playing)
is there a way to install it?

Thanks,
Wade
EDIT: I have A VOD of it not working

Wade, there are different versions of the DOS version of Maniac floating around. The most common version is the one, that when given to ScummVM, will have the lab door able to accept any and all codes.

If you can be more specific of where you acquired this version of Maniac, I might be able to help you out here. I can't provide links to download one of the many versions that are already deprotected (i.e., if run under DOS or DOSBOX, will have a closed-but-any-code-will-work Steel Security Door as well as a any-code-will-work Lab Door) and I would assume it is against the forum rules to ask where you can find them. Sorry.

And please post the VOD, I am very curious.

To clear this up, though, my understanding has been this:

If you give ScummVM a vanilla, unchanged, uncracked version of PC Maniac Mansion v2 (1989), this will happen:
1. Steel Security Door at the top of the steps will always been opened
2. The Lab Door will be set to a code that you cannot enter until you fix the arcade machine

If you give ScummVM a cracked version of PCManiac Mansion v2 (1989), which is pretty much what everyone has:
1. Steel Security Door will always be opened
2. The Lab Door will accept any code -- 0000, 0001, 1234, etc

So Wade I am assuming that you are using an uncracked version of the USA PC version of Maniac Mansion v2? That can be the only ay I could see this happening...

 
  mattmcgrath

Please try running this under DOSBox and tell me if the Steel Security Door (the one that you see at 2:50 of your submitted VOD here) will accept any codes or if it blows up after 3 incorrect entries.

If it accepts any codes, then it is cracked, and it seems the crack is different than the V2 "lab door mod" crack. If it doesn't accept any random codes after a few tries, then we can go from there.

Thanks so much for bringing this up -- it would be good for me or someone else to write a comprehensive comparison chart for the vast number of different versions of this game, ha!

Ok, as we expected, there are multiple versions of the first version of Maniac Mansion (V1, 1988) for PC.

There's the completely uncracked version, which under ScummVM will have the Steel Security Door Open, but not the Lab Door Mod. Under DOSBox, the Steel Security Door will be closed and will require a correct code to pass.

There's a cracked version that is similar to the V2 Lab Door Mod where the door Steel Security Door is closed under DosBox but will be opened with any code, as well as the Lab Door.

However, as Wade showed here (and to me), there's a crack for V1 that does not allow any code to be entered in for the Lab Door (i.e. you must fix the wires for the Meteor Mess game in order for a code to appear as well as having the lab door accept the code), but even under DosBox will have the Steel Security Door permanently open.

If you wish to run the V1 (1988) PC version of the game using the current route, you must not have the version that Wade has here.
