====Goldberg Steam Emulator====
|
|
---
|
|
|
|
An emulator that supports LAN multiplayer without steam.
|
|
https://gitlab.com/Mr_Goldberg/goldberg_emulator
|
|
|
|
---
|
|
|
|
## How to use:
|
|
1. Replace the `steam_api(64).dll` (Windows) or `libsteam_api.so` (Linux) from the game with the emu.
|
|
2. Use the command line tool `generate_emu_config` to generate the `steam_settings` folder
|
|
3. Use the command line tool `generate_interfaces` to generate the file `steam_interfaces.txt`,
|
|
then move it inside the folder `steam_settings`
|
|
4. Move the entire folder `steam_settings` beside the emu .dll/.so.
|
|
|
|
|
|
Mr.Goldberg's note:
|
|
> If the game has DRM (other than steamworks) you need to remove/crack it first.
|

|
|
## Saves location:
|
|
* On Windows:
|
|
`C:\Users\<Your windows user name>\AppData\Roaming\Goldberg SteamEmu Saves\`
|
|
* On Linux:
|
|
* if `XDG_DATA_HOME` is defined:
|
|
`$XDG_DATA_HOME/Goldberg SteamEmu Saves/`
|
|
* Otherwise:
|
|
`$HOME/.local/share/Goldberg SteamEmu Saves/`
|
|
|
|
---
|
|
|
|
In the settings folder in that save location you will find 3 files (if you have used the emulator at least once):
|
|
account_name.txt (Edit this file to change your name)
|
|
listen_port.txt (Edit this file if you want to change the UDP/TCP port the emulator listens on (You should probably not change this because everyone needs to use the same port or you won't find yourselves on the network))
|
|
user_steam_id.txt (this is where your steam id is saved, you can change it (if your saves for a game are locked to a specific steam id see below for a way to change it on a per game basis) but it has to be valid)
|
|
language.txt (Edit this to change the language the emulator will report to the game, default is english, it must be a valid steam language name or the game might have weird behaviour (list provided at the end of this readme))
|
|
|
|
Note that these are global so you won't have to change them for each game. For game unique stuff (stats and remote storage) a folder is created with the appid of the game.
|
|
If you want to change your steam_id on a per game basis, simply create a settings folder in the game unique directory (Full path: C:\Users\<Your windows user name>\AppData\Roaming\Goldberg SteamEmu Saves\<appid>\settings)
|
|
In that settings folder create a user_steam_id.txt file that contains the valid steam id that you want to use for that game only.
|
|
|
|
You can also make the emu ignore certain global settings by using a force_account_name.txt, force_language.txt, force_listen_port.txt or force_steamid.txt that you put in the <path where my emu lib is>\steam_settings\ folder.
|
|
See the steam_settings.EXAMPLE folder for an example.
|
|
|
|
If for some reason you want it to save in the game directory you can create a file named local_save.txt right beside steam_api(64).dll (libsteam_api.so on linux)
|
|
The only thing that file should contain is the name of the save directory. This can be useful if you want to use different global settings like a different account name or steam id for a particular game.
|
|
Note that this save directory will be beside where the emu dll (or .so) is which may not be the same as the game path.
|
|
|
|

|
|
|
|
## DLC:
|
|
By default the emulator will try to unlock all DLCs (by returning true when the game calls the `BIsDlcInstalled()` function).
|
|
If the game uses the other function you will need to provide a list of DLCs to my emulator.
|
|
|
|
To do this first create a `steam_settings` folder right beside where you put my emulator.
|
|
In this folder, put a `DLC.txt` file. (path will be `<path where my emu lib is>\steam_settings\DLC.txt`)
|
|
|
|
If the DLC file is present, the emulator will only unlock the DLCs in that file. If the file is empty all DLCs will be locked.
|
|
|
|
The contents of this file are:
|
|
`appid=DLC name`
|
|
|
|
See the steam_settings.EXAMPLE folder for an example.
|
|
|
|
---
|
|
|
|
## Languages:
|
|
You can include a `steam_settings\supported_languages.txt` file with a list of languages that the game supports.
|
|
|
|
If the global emu language setting is not in this list of languages, the emu will default to the first language in the list.
|
|
|
|
See the `steam_settings.EXAMPLE` folder for an example.
|
|
|
|
---
|
|
|
|
## Depots:
|
|
This is pretty rare but some games might use depot ids to see if dlcs are installed.
|
|
You can provide a list of installed depots to the game with a `steam_settings\depots.txt` file.
|
|
|
|
See the `steam_settings.EXAMPLE` folder for an example.
|
|
|
|
---
|
|
|
|
## Subscribed Groups:
|
|
Some games like payday 2 check which groups you are subscribed in and unlock things based on that.
|
|
You can provide a list of subscribed groups to the game with a `steam_settings\subscribed_groups.txt` file.
|
|
|
|
See `steam_settings.EXAMPLE\subscribed_groups.EXAMPLE.txt` for an example for payday 2.
|
|
|
|
---
|
|
|
|
## Subscribed Groups (Clans):
|
|
Some games like counter-strike check which groups you are subscribed in and allow you to choose a group clan.
|
|
You can provide a list of subscribed group ids, names, and tags to the game with a `steam_settings\subscribed_groups_clans.txt` file.
|
|
|
|
Group ids must be valid and can be obtained by pasting '`/memberslistxml/?xml=1`' at the end of a Steam group page.
|
|
|
|
See `steam_settings.EXAMPLE\subscribed_groups_clans.EXAMPLE.txt` for an example.
|
|
|
|
---
|
|
|
|
## App paths:
|
|
Some rare games might need to be provided one or more paths to app ids.
|
|
For example the path to where a dlc is installed.
|
|
This sets the paths returned by the `Steam_Apps::GetAppInstallDir` function.
|
|
|
|
See `steam_settings.EXAMPLE\app_paths.EXAMPLE.txt` for an example.
|
|
|
|
This file should be put here: `<path where my emu lib is>\steam_settings\app_paths.txt`
|
|
|
|
Note that paths are treated as relative paths from where the steam_api dll is located.
|
|
---
|
|
|
|
---
|
|
|
|
## Mods:
|
|
Put your mods in the `steam_settings\mods\` folder.
|
|
|
|
Mod data folder must be a number corresponding to the file id of the mod.
|
|
|
|
See the `steam_settings.EXAMPLE` folder for an example.
|
|
|
|
---
|
|
|
|
## Steam appid:
|
|
Put your `steam_appid.txt` in the `steam_settings` folder because this is where the emulator checks first.
|
|
|
|
If there is no `steam_appid.txt` in the `steam_settings` folder it will try opening it from the run path of the game.
|
|
If one isn't there it will try to load it from beside my steam api dll.
|
|
|
|
The steam appid can also be set using the `SteamAppId` or `SteamGameId` env variables (this is how real steam tells games what their appid is).
|
|
|
|
But it is highly recommended to always create this file inside `steam_settings` folder
|
|
---
|
|
|
|
---
|
|
|
|
## Offline mode:
|
|
Some games that connect to online servers might only work if the steam emu behaves like steam is in offline mode.
|
|
If you need this, create `offline.txt` file in the `steam_settings` folder.
|
|
|
|
---
|
|
|
|
## Disable networking:
|
|
If you want to disable all the networking functionality of the emu, you can create a `disable_networking.txt` file in the `steam_settings` folder.
|
|
**This will of course break all the networking functionality** so games that use networking related functionality like lobbies or those that launch a server in the background will not work.
|
|
|
|
---
|
|
|
|
## Custom Broadcast IPOs:
|
|
If you want to set custom ips (or domains) which the emulator will send broadcast packets to, make a list of them, one on each line in: `Goldberg SteamEmu Saves\settings\custom_broadcasts.txt`
|
|
|
|
If the custom IPs/domains are specific for one game only you can put the `custom_broadcasts.txt` in the `steam_settings` folder.
|
|
|
|
An example is provided in `steam_settings.EXAMPLE\custom_broadcasts.EXAMPLE.txt`
|
|
|
|
---
|
|
|
|
## Achievements, Items or Inventory:
|
|
Create a file named `items.json` and/or `achievements.json` inside the `steam_settings` folder which will contain every item/achievement you want to have in your game.
|
|
|
|
An example can be found in `steam_settings.EXAMPLE` that works with Killing Floor 2.
|
|
|
|
The `items.json` syntax is simple, you **SHOULD** validate your `.json` file before trying to run your game or you won't have any item in your inventory.
|
|
Just look for "online json validator" on your web brower to valide your file.
|
|
|
|
You can use https://steamdb.info/ to list items and attributes they have and put them into your .json, you can also use the command line tool `generate_emu_config`.
|
|
|
|
Keep in mind that some item are not valid to have in your inventory.
|
|
---
|
|
For example, in PayDay2 all items below `item_id` `50000` will make your game crash.
|
|
* `items.json` should contain all the item definitions for the game,
|
|
* `default_items.json` is the quantity of each item that you want a user to have initially in their inventory. By default the user will have no items.
|
|
|
|
It is recommended to use the command line tool `generate_emu_config` for that matter
|
|
|
|
---
|
|
|
|
## Leaderboards:
|
|
By default the emulator assumes all leaderboards queried by the game `FindLeaderboard()` exist and creates them with the most common options (sort method descending, display type numeric).
|
|
In some games this default behavior doesn't work and so you may need to tweak which leaderboards the game sees.
|
|
|
|
To do that, you can put a `leaderboards.txt` file in the `steam_settings` folder.
|
|
An empty `leaderboards.txt` makes the emu behave as if any leaderboard queried by the game using `FindLeaderboard()` does not exist.
|
|
|
|
The format is:
|
|
`LEADERBOARD_NAME=sort method=display type`
|
|
|
|
For the sort methods:
|
|
* 0 = none
|
|
* 1 = ascending
|
|
* 2 = descending
|
|
|
|
For the display type
|
|
* 0 = none
|
|
* 1 = numeric
|
|
* 2 = time seconds
|
|
* 3 = milliseconds
|
|
|
|
An example can be found in `steam_settings.EXAMPLE`
|
|
|
|
---
|
|
|
|
## Stats:
|
|
By default this emulators assumes all stats do not exist unless they have been written once by the game.
|
|
This works for the majority of games but some games might read a stat for the first time
|
|
and expect a default value to be read when doing so.
|
|
|
|
To set the type for each stat along with the default value, put a `stats.txt` file in the `steam_settings` folder.
|
|
The format is:
|
|
`STAT_NAME=type=default value`
|
|
|
|
The type can be
|
|
* int
|
|
* float
|
|
* avgrate
|
|
|
|
The default value is simply a number that represents the default value for the stat.
|
|
|
|
You can use the command line tool `generate_emu_config` to generate a stats config
|
|
|
|
---
|
|
|
|
## Build id:
|
|
Add a `steam_settings\build_id.txt` with the build id if the game doesn't show the correct build id and you want the emu to give it the correct one.
|
|
|
|
An example can be found in `steam_settings.EXAMPLE`
|
|
|
|
---
|
|
|
|
## SteamHTTP:
|
|
Add a `steam_settings\http` folder.
|
|
The folder should contain the domain name and path to the files that will be returned by steamHTTP like so \(For example this url: `https://en.wikipedia.org/wiki/Main_Page`\):
|
|
|
|
* Create a folder `steam_settings\http\en.wikipedia.org\wiki\Main_Page`
|
|
* The `Main_Page` **file** would contain the data returned by the steamHTTP api when it tries to access: `https://en.wikipedia.org/wiki/Main_Page`
|
|
|
|
An example that was made for payday 2 can be found in `steam_settings.EXAMPLE`
|
|
|
|
To allow external downloads which will be stored in this `steam_settings\http` folder copy the `disable_lan_only.txt` file to the `steam_settings` folder.
|
|
|

|
|
|
|
## Avatar:
|
|
Copy a `PNG` or `JPG` image to your `Goldberg SteamEmu Settings\settings` folder and name it `account_avatar`
|
|
|
|
You can also set a default profile picture for users who are missing one by copying a similar file called `account_avatar_default`
|
|
|
|
You can find example in `steam_settings.EXAMPLE`
|
|
|

|
|
|
|
## Support for CPY steam_api(64).dll cracks:
|
|
See the build in the experimental folder.
|
|
|
|
**Notes:**
|
|
You must all be on the same LAN for it to work.
|
|
|
|
**IMPORTANT:**
|
|
Do not run more than one steam game with the **same appid** at the same time on the same computer with my emu or there might be network issues (dedicated servers should be fine though).
|
|
|
|
---
|
|
|
|
## Overlay:
|
|
**Note: at the moment this feature is only enabled in the windows experimental builds**
|
|
---
|
|
|
|
The overlay can be disabled by putting a file named `disable_overlay.txt` in the `steam_settings` folder.
|
|
|
|
This is for games that depend on the steam overlay to let people join multiplayer games.
|
|
Use `SHIFT-TAB` to open the overlay.
|
|
|
|
---
|
|
|
|
## Controller:
|
|
**Note: at the moment this feature is only enabled in the windows experimental builds and the linux builds**
|
|
---
|
|
|
|
SteamController/SteamInput support is limited to **XInput** controllers.
|
|
If your controller is not XInput, there are many tools (at least for windows) that you can use to make it emulate an XInput one.
|
|
|
|
Steam uses things called action sets for controller configuration. An action set is a group of action names.
|
|
Action names are bound to buttons, triggers or joysticks.
|
|
The emulator needs to know for each action set, which button is linked to which action name.
|
|
|
|
Create a `ACTION_SET_NAME.txt` file in the `steam_settings\controller` folder for every action set the game uses.
|
|
|
|
To see an example for the game Crystar see: `steam_settings.EXAMPLE\controller.EXAMPLE`
|
|
|
|
In the action set txt files the format is:
|
|
* For digital actions (buttons, on or off):
|
|
`ACTION_NAME=BUTTON_NAME`
|
|
* For analog actions (joysticks, triggers):
|
|
`ACTION_NAME=ANALOG_NAME=input source mode`
|
|
|
|
Actions can be bound to more than one button by separating the buttons with, like this:
|
|
`ACTION_NAME=A,B`
|
|
|
|
You can use the command line tool `generate_emu_config` to generate a config file.
|
|
Or if you want to configure a game yourself, find the xbox360 or xbox one `vdf` file for the game and you should be able to figure things out.
|
|
|
|
For example to get the vdf file for the game Crystar: https://steamdb.info/app/981750/config/
|
|
If you look at: `steamcontrollerconfigdetails`, you will see something like: `1779660455/controller_type: controller_xbox360`
|
|
`1779660455` refers to a file id that you can dl using your favorite steam workshop downloader site.
|
|
The url would be: https://steamcommunity.com/sharedfiles/filedetails/?id=1779660455
|
|
|
|
The glyphs directory contains some glyphs for the controller buttons for the games that use the `GetGlyphForActionOrigin()` function.
|
|
If you want to use the real steam glyphs instead of the free ones in the example directory copy them from: `<Steam Directory>\tenfoot\resource\images\library\controller\api` folder.
|
|
|
|

|
|
|
|
## Auth token (app ticket):
|
|
|
|
By default the emu will send the old token format for various APIs, like:
|
|
* `Steam_GameServer::GetAuthSessionTicket()`
|
|
* `Steam_User::GetAuthSessionTicket()`
|
|
* `Steam_User::GetAuthTicketForWebApi()`
|
|
|
|
You can make the emu generate new ticket data, and additionally the GC token.
|
|
Check the relevant files `new_app_ticket.txt` and `gc_token.txt` in the `steam_settings` folder
|
|
|
|
---
|
|
|
|
## Branch name and type:
|
|
|
|
By default the emu will report a `non-beta` branch with the name `public` when the game calls `Steam_Apps::GetCurrentBetaName()`
|
|
|
|
Check the relevant files `is_beta_branch.txt` and `force_branch_name.txt` in the `steam_settings` folder
|
|
|

## More configurations:
|
|
Due to the various changes and additions, it became tedious to document everything,
|
|
so it is recommended to check each example file in the `steam_settings` folder.
|
