Multiworld

From OoT Randomizer Wiki

Jump to:navigation, search

The aim of this page is to help the reader fix Bizhawk for Multiworld. Multiworld is a co-op modern for the OoT Randomizer. Players accept their own inventory and their ain world. Also, player-specific items are mixed between the worlds. For example, if yous obtain an item in your world, it could either stay with you or get sent to another player. Everyone participating volition be playing different intermingled seeds.

As an example, there could be a scenario where Actor 1 can only accelerate in their own earth based on something Player 2 does. One time Player two finds the Megaton Hammer belonging to Player 1, Role player 1 will automatically receive it. Every world is linked together.

In order to link anybody'due south worlds together, players demand to make apply of "lua scripts". These are simply compatible with Bizhawk, yet the ModLoader64 devs have fabricated a copy which is compatible with their emulator and the OoT Online pak, allowing players to play without a "host" and to meet each other'due south character in the game. (For help with ModLoader64, please join their Discord.) Support for other emulators, besides as panel back up, is planned for futurity releases.

Generating the Seeds

Using the Webpatcher

Kickoff off by going to the Webpatcher and set up the settings you desire for the seed. On the Rom Options tab change the Role player Count to however many people will be playing. Once you're done, generate the seed.

Afterward yous accept generated the seed, share the URL with your partners and have everyone choose a dissimilar Player ID. And then continue patching the rom as you would normally (don't forget cosmetics and sfx). Each role player should accept their own Randomizer ROM, with the formula OoT_SeedID_SettingsHash_W0P0 with the W0 and P0 being world count and role player ID respectively.

Using the Offline Version

Generating a ROM using an offline build works a little differently. After choosing the settings you wish to play with, become to the ROM Options tab and set Generate New Seed (Generate From Seed in previous versions). Choose Patch File as your Output Type and change the Histrion Count to however many people will be playing. Then hitting Generate!.

Send the patch file (.zpfz) to your partners and accept them set Generate From File. The Output Blazon should be Compressed [Stable] now, and everyone should choose a different Player ID. Select the patch file and hitting Generate! (don't forget to set up cosmetics and sfx). Each player should have their own Randomizer ROM, with the formula OoT_SeedID_SettingsHash_W0P0 with the W0 and P0 being world count and actor ID respectively.

Notation: if your partners don't have the offline build they tin also patch the rom using the website. Brand sure to ready Generate From File and select your patch file (.zpfz).

At that place are several reasons why someone might want to generate a ROM using an offline build. For example, some builds might accept features that are not bachelor on the website build (still), like additional Entrance Randomizer settings. Generating from an offline build also lets you lot play with your ain custom patches.

Installing Multiworld and Bizhawk

The Recommended Method

Press Windows+R to open the Run dialog box, so type "powershell" in the text box. In one case you have your PowerShell window open up, copy-paste this in:

cd $env:userprofile\downloads; Set-ExecutionPolicy Bypass -Telescopic Process -Strength; [Organization.Cyberspace.ServicePointManager]::SecurityProtocol = [Organization.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object Organization.Net.WebClient).DownloadString('https://raw.githubusercontent.com/TestRunnerSRL/bizhawk-co-op/principal/bizhawk-co-op.ps1'))

From here, the PowerShell is getting y'all 99% of the way done: it volition create a new Bizhawk 2.seven install in your downloads binder and place everything for you. Say yes when PowerShell prompts you to install the bizhawk_prereqs.exe file. Once PowerShell is done, you tin can move the Bizhawk 2.7 binder somewhere else if you wish. Afterwards, open up the Bizhawk ii.seven folder it created and launch EmuHawk.exe.

The Alternate Method

Download the Custom Bizhawk Installer

First, yous must download the Multiworld script from TestRunner's GitHub page. When you download this, extract its contents to its own folder - it will be creating a new Bizhawk install for you to use, then you must keep information technology dissever. Note: Whenever there is an update to the Multiworld script, everybody playing must update to the latest version.

Running the Custom Bizhawk Installer

Once you lot have the contents extracted to its ain folder, locate the bizhawk-co-op.ps1 file. Right Click and select Run with PowerShell.

If Powershell prompts you for permissions, say yep to all. From here, the Powershell is getting y'all 99% of the way washed: it volition create a new Bizhawk 2.7 install and place everything for y'all. In one case Powershell is done, open up the Bizhawk 2.7 folder it created and launch EmuHawk.exe. Note: It is recommended you delete everything exterior of the Bizhawk 2.7 folder that was created. These files are no longer needed and only add confusion.

Powershell Permissions

Yous may demand to enable executing Powershell scripts without requiring the script to be digitally signed. Open Powershell from the Showtime Menu by right clicking information technology and selecting "Run as Admin". Click the "Yes" button to allow Powershell to run as Administrator. Blazon Set up-ExecutionPolicy Unrestricted and press Enter once, type Y then press Enter again. The Powershell script should now run.

Configuring Bizhawk for Multiworld

Bizhawk Settings

There are a few things you demand to do in one case you lot've got the emulator running. The very first affair is go to Config -> Customize and navigate to the Advanced tab. At the bottom, in that location is an choice for Lua Cadre; select Lua+LuaInterface and hit OK. While on the Advanced tab, you should also check the box for AutoSaveRAM and set it to a reasonable time, such equally sixty-180 seconds (proceed in mind that setting this too low could increase lag and decrease overall emulator operation). This will allow Bizhawk to write your in-game save to your bulldoze. This is Not a form of relieve state - information technology simply periodically creates/updates a file on your hard bulldoze with your in-game save data, and is wonderful for mitigating the effects of crashes. In the event of a crash (or if yous open TAStudio by blow) Do NOT RELOAD THE ROM! DO Non RELOAD THE ROM! Doing so will overwrite your backups, meaning that your relieve files volition be gone. To recover your relieve file follow the instructions over hither.

In the Full general tab of the Customize menu, tick the boxes for "Accept groundwork input" and "Run in background" – this volition permit Bizhawk to keep accepting controller inputs when you tab over to your tracker or notes and prevent the emulation from pausing (which will disconnect you). Clear your hotkeys by going to Config -> Hotkeys, and at the bottom click Misc and Clear All.

Controller Settings

The next step is to set your controller up. Your controller configuration will vary based on what controller you are using; for Bizhawk to enable the Controller menu, yous must take a ROM loaded. For a polish controller feel, y'all must unbind the first 4 binds in Config -> Controller such that it looks like this:

You'll then accept to bind your analog stick in the Analog tab of your controller config and adjust your sensitivity and deadzones to your preference. Additional info on controller setup can be found in Step 6 of the Bizhawk Guide.

Video Settings

Yous can set how your game looks by going to Config -> Cores -> N64 Video Plugin Settings. In hither, change your resolution so that it runs smooth. Multiworld will drop your performance, so keep that in mind. The recommended video plugin is GLideN64. (This is non the same plugin as Glide64!)

Starting the Multiworld Session

Opening the Lua Console

Once you lot have your emulator set up to run how you are comfortable with, its time to move to the Lua console. Go to Tools -> Lua Console, and a separate window will open up upwardly. This window must remain open up at all times during a Multiworld. In the Lua Console, become to Settings and checkmark the Disable Scripts on loads.

This is the concluding of the settings changes y'all have to do. If yous desire Bizhawk to retain these settings changes for the next fourth dimension, go to Config -> Save Config. Once yous have these steps washed, you lot MUST close your emulator and reopen it for this change to take effect. Close out of Bizhawk, and so reopen it and the Lua Console. Sometimes this will non be enough and you will nonetheless get an error trying to load the Lua file. In that example reboot your unabridged computer.

If for some reason you do non have your Multiworld ROM open, you must practice so at present.

From here in the Lua Console, Open Script and locate the bizhawk co-op.lua file in the Bizhawk two.7 folder. One time you have that washed, a ruby square will announced in the console; double click it and a new window volition open up.

This window must also stay open up at all times.

Rooms

The Lua Console Script is where you prepare a room and join rooms.

If you lot are the Host: You must port forward. How you lot do this varies on what brand your router is. Instructions on how to exercise this can be found by Googling your make/model of router. You'll desire to utilize a port between 49152 and 65535. We highly recommend using the default port, 50000. You'll also want to ensure y'all're forwarding the TCP protocol as that is the protocol Multiworld uses. Near other games you take port forwarded in the by likely were using the UDP protocol.

Once that is done, in the Bizhawk Co-op window the Host must set their name, password, and the port that was forwarded, along with setting the game script to Ocarina of Time. Don't set the IP address. Hit Create Room and tell the people joining the Room Name (= your name), countersign, and port. (It is not recommended to use your own personal password hither, as information technology is shared with the grouping. Utilize something that will prevent random people from joining your room, but not something that will compromise your own security.)

If y'all are Joining and the Host has fix the room: hitting Refresh in the Bizhawk Co-op window and select the Host's Room from the dropdown bar. When you input your username, go on in mind the game will employ this to brandish who got what detail for everyone playing. Information technology will max out at 8 characters, fifty-fifty if you input more. Fill in the countersign and port number the Host gave y'all and select the Ocarina of Time Game Script and hit Join Room.

You lot tin can likewise select a role player number when both hosting and joining a room. This is not-mandatory, and player numbers will be automatically selected if non are entered. This besides does not demand to friction match the globe number chosen when patching your ROM file. If y'all do select a role player number, and that number is already filled in that room, you will exist unable to join.

Play Some Multiworld!

Go and have fun with new or erstwhile friends! If you are part of the Ocarina of Time Randomizer Discord, y'all tin assign the Multiworld role to yourself by going to the #role-assignment aqueduct and clicking the iii emote - this volition allow y'all to receive pings in the server where there are announcements from the Devs or folks are looking for players. You can also visit #multiworld-planning to wait for additional players. It is highly recommended that y'all use one of the Trackers so that you don't accidentally exit those new friends out to dry if you miss a cheque. Map Trackers such as 2deep4real's Web Tracker or Hamsda's Map and Item Tracker package for EmoTracker are highly recommended.

Troubleshooting

Installation Bug (Applies to both the Recommended and Alternate Methods)

Windows seven

If y'all are running Windows vii you will need to enable remote Powershell script execution, and make certain Powershell is updated.

First, go to the Installing Powershell folio and navigate to the download page for the the latest Windows 7 SP1 Powershell version. At the time of writing information technology is WMF 5.ane. The file on the download page you want to download is named similar to Win7AndW2K8R2-KB3191566-x64.zip. Run the .msu file inside of the zero file and information technology should update Powershell.

Anti-Virus

Another issue that can occur while running the Powershell script is your anti-virus deleting the files it downloads. The BizHawk Prerequisites often gets marked every bit suspicious due to information technology existence an installer that runs more installers. We tin can't give a detailed guide on how to exclude a binder in every anti-virus software, but search Google with a query like Exclude Folder <your_anti-virus_name> and you should find a guide on their official site explaining how to do so. Exclude the binder that has the Powershell script in it and now you should be able to run it without the downloaded files getting deleted.

Common Error Messages

These are the nearly common errors that pop up that accept known solutions. If none of these solve the problem, effort rebooting your computer again afterwards to ensure whatever new configurations are fully loaded.

NullHawk Does Not Implement Retentiveness Domains

You lot must load the ROM before activating the Lua scripts.

If doing so does not prepare the result, open the Lua Console and look at Settings -> Autoload. This setting should exist disabled. Save the settings and completely close out of Bizhawk. Reopen, load the rom, and only later on the rom is loaded open the Lua Console.

Error 401

This mostly ways that either the password entered was wrong, or that the room name already exists. Also, avoid special characters like spaces in the room name. We recommend using letters (no accents) and numbers only.

This ROM is not uniform with this version of the co-op script.

Update your scripts.

Unable To Find Domain: CARTROM

You lot are using the A Link to the By LUA script. Choose Ocarina of Time in the dropdown instead.

Dynamic Libraries Non Enabled

You lot did not set the Lua Core setting properly. Remember to restart Bizhawk later irresolute it.

Unprotected Error in Call to LUA API

This is a general fault that pops up randomly. You lot need to ensure all copies of Bizhawk are closed properly. The easiest way to ensure this is by rebooting your computer.

If y'all consistently get information technology when trying to start upward the script, make sure the script is located in the Bizhawk root folder. This error volition come up up if you run the script from any other binder.

Connection Failed: Timeout

There are several reasons this tin happen, all of them being various methods of misconfiguration.

First, the host must have the port being used forwarded if non using Hamachi. Your private IP address that y'all frontwards the port to tin can change for diverse reasons. Always ensure that the router is pointing to the right reckoner with the port forwarding options. The host must also not have pings blocked in their router settings. This setting can be found under many names depending on the router.

Anybody playing must accept the Bizhawk emulator immune through their firewall.

The above Bizhawk configuration options are not optional. If you practise not configure the emulator properly you will exist unable to stay connected to each other.

Invalid Arguments to Method Call

You'll go this error if files are in the wrong place. This can happen if you motility any of the files manually, or if the Powershell script exits early on.

The easiest way to set up this is to remove the Bizhawk binder and re-run the Powershell script. If your bizhawk-co-op.lua file is in the Lua folder, yous can endeavor moving it to the root binder where EmuHawk.exe is instead and see if that works also.

Endeavour to concatenate local 'err'

This error occurs when some part that was downloaded was corrupt. The easiest fashion to fix this is to delete the Bizhawk folder the Powershell script downloaded and run it again.

Miscellaneous Problems

A Specific Particular Failed to Transfer

Items can be retrieved by having the receiving role player enter a line of code into the Lua console, though information technology is best to avoid this situation entirely if possible. This frequently occurs if a role player continues while 1 or more other players are disconnected from the room. To prevent this, always ensure everyone is connected before collecting any item.

Go to this website (fabricated past pidgezero_one) and select option two. Locate the code for the missing item and follow the instructions in that location to retrieve the item. If the layout looks wrong, printing ctrl+F5 to fix information technology.

Aid! My emulator crashed!/I accidentally opened TAStudio and got a blackness screen!

First of all, DO NOT RELOAD THE ROM! DO NOT RELOAD THE ROM! Doing and so volition overwrite your backups, meaning that your save files will be gone. To recover your save files follow these instructions.

1. In your Bizhawk folder navigate to \N64\SaveRAM.
2. Identify the SaveRAM and AutoSaveRAM files corresponding to your seed. Sorting by date may help. Note that the AutoSaveRAM files will only exist if you've enabled that beforehand.
3. Optional: manually make a fill-in of these files somewhere on your pc.
4. Delete the SaveRAM file and rename AutoSaveRAM to take the place of the SaveRAM file you've simply deleted.
5. At present y'all can safely load your seed again and continue playing.

A Player Forfeits without Finishing

If a player forfeits their world, the game can go along without them by entering code lines into the Lua console to retrieve the lost items for the remaining players. Upload the multiworld spoiler log on this site (made past pidgezero_one) and follow the instructions there. If the layout looks wrong, printing ctrl+F5 to fix it.

LUA Panel Window Likewise Modest

If your window for the LUA connexion console is too modest and the elements are overlapping, you need to change your DPI settings. Right click EmuHawk -> Properties -> Compatability -> Loftier DPI scaling override, alter to "System (Enhanced)".

Multiworld Without Port-Forwarding or Bizhawk

Hamachi

If nobody in your multiworld group can port-forward for whatever reason, and you cannot get someone who can to join, so there is a plan you tin use: Hamachi. Let me preface this past saying that Hamachi basically 'tricks' your computers to believe that you are all connected via LAN.

To start, download Hamchi [here] and install it. Create an account, and become to System > Preferences > Settings to make certain that 'Encryption' is enabled. And so, click on the power button to become online.

Hosting

If yous're hosting, and so click Network > Create a new network. Give it a unique proper noun and countersign, making sure that nobody other than the people y'all're playing with find out this information. After this, you'll see it pop onscreen:

To join an existing network, click Network > Bring together an existing network. Blazon in your friend's network ID and the network's countersign.

Once you're all connected in the network, yous tin get-go the multiworld.

Right click on the address above your nickname, and click 'Copy IPv4 accost' and share it with the people joining yous:

Then, outset upwardly the Bizhawk co-op lua script. Set 'Rooms' to '(Custom IP)', Set up your Username and Password as usual, and the game script to Ocarina of Time.

Joining

And so, start upwardly the Bizhawk co-op lua script. Prepare 'Rooms' to '(Custom IP)' and paste the IPv4 the host gave you into the 'Host IP' bar. Set your Username and Countersign as usual, and the game script to Ocarina of Fourth dimension.

Now you should be ready to first. As usual, if you have any more than bug, seek advice within the Ocarina of Time Randomizer Discord.

Security Sensation

Be conscientious with who yous give permission to bring together your network to. Using Hamachi is like letting anybody using it with you use a estimator on the aforementioned network as yours.

Hamachi Asking Timed Out

Follow these steps to ensure Hamachi is allowed through your firewall. Both the Host and the clients connecting to the host should do this.

Playing over LAN

If y'all're playing over a LAN network, so all you need to practise is ready the 'room' to (Custom IP), blazon the LAN's Ipv4 into the 'host IP' field, and give yourself a username. Leave the password field bare.

Play Without Bizhawk

While Bizhawk is the officially supported emulator for multiworld, it is known to exist a resources-intensive emulator in add-on to being Windows only. If using Bizhawk is impossible for whatsoever reason, try the emulator ModLoader64 (Windows and Linux compatible), equally DemoXin has modified the multiworld script to work with it. This method does non crave a host. Modloader64 is also the merely way to play Ocarina of Time Online, which allows players to run across each other in the world, and as well supports other various features. As nosotros practice not officially back up this emulator or any of their paks, we kindly refer you lot to their Discord for all problems and support.
