[FAQ] Retrobat [WIP]

[30] How to add SWITCH, Yuzu and RyujinX emulators?

To add the Nintendo Switch emulators, "Yuzu" and "RyujinX", which are not included in Retrobat, you must download these emulators from their respective websites.
Then install them on your computer and move the contents of the installation folders to the \emulators folder of your Retrobat installation.

/!\ This little tutorial is not made to explain how to configure and add the firmware/bios and other keys needed to use these emulators.



For Yuzu:


Where to download it?

here: https://yuzu-emu.org/downloads/

Where is it located?
here: C:\Users\*YOUR USER*\AppData\Local\yuzu\yuzu-windows-msvc


Folder content:




Where to copy it?
In the folder \emulators\yuzu of your Retrobat installation.






To make Yuzu portable, you need to put the necessary files in \emulators\yuzu\user




For RyujinX:

Where to download it?
here: https://ryujinx.org/download (version Windows)

Where is it located?
This is a .zip file, not an installer, so unzip the contents of the "publish" folder from the zip directly into \emulators\ryujinx of your Retrobat installation.





The \emulators\ryujinx\portable folder, as the name suggests, is used to make RyujinX portable.
More informations about that: https://github.com/Ryujinx/Ryujinx/wiki/Ryujinx-Setup-&-Configuration-Guide#portable-mode

[31] Why are some emulator folders empty?

You may have noticed that the folders present in \emulators\ are empty. Some of them, because the consoles concerned are still on the market (it's the case for the Nintendo Switch with the Yuzu and RyujinX emulators). For the MAME standalone emulator and Teknoparrot, simply because it would make the Retrobat setup much heavier (which is already more than a GB). For Pico8, because it's a paid emulator.

So it's up to you to download them on their respective websites, and to put them in the corresponding folders.

[32]Why do I get the message ? "WE CAN'T FIND ANY SYSTEMS!" or "It looks like your systems configuration file has not been set up or is invalid..."


- You have just installed RetroBat, and when you launch Retrobat.exe this message appears:




Obviously your installation did not go well, delete the installation folder, and start the installation of RetroBat again.


- Your Retrobat was working fine until now, but you still get this message.

There is a possibility that one or more Retrobat system files (es_systems.cfg) are corrupted, in which case you will need to redo a Retrobat installation.

But maybe you modify them. This is not recommended, we will not do any support if it does.



- If you see this message:
"It looks like your systems configuration file has not been set up or is invalid. You'll need to do this by hand unfortunately.
Visit emulationstation.org for more information."



The Windows environment variable of your PC is probably "HOME" This Variable is not compatible with Retrobat.

[33] How to create a custom "es_system.cfg"?

Many of you want to annoyed us "tweak" Retrobat, especially when you want to add a RetroArch core or add a standalone emulator.

We strongly recommend that you don't modify the es_system.cfg file located in \emulationstation\.emulationstation\, because when it’s time for a Retrobat update, all your changes would be erased.

But if you are stubborn a real hacker, there is a workaround to prevent your changes from being destroyed after a Retrobat update.


Example:

You want to modify the Gamecube system.

Go to the \emulationstation\.emulationstation\ folder and open the es_system.cfg file within a text editor: Notepad or Notepad ++ (for example.)

And in that file, look for the Gamecube system:



As on the screenshot above, select the Gamecube system from the <system> tag up to </system> and make "copy" (right click "copy", or ctrl + c)



At the root of the \emulationstation\.emulationstation\ folder, create a blank .txt file and do "paste" (right click "paste", or ctrl + v):


/!\ Don't forget to add <systemList> at the beginning and </systemList> at the end.

Close the file and save it.

Then rename to es_systems.cfg but add the name of the system at the end of the file name: New document text.txt becomes es_systems_gamecube.cfg


Now Retrobat will prioritize the es_systems_gamecube.cfg file for the Gamecube system.

You can therefore make modifications to this custom file, without touching the main es_systems.cfg file.

Note that BatGui.exe also allows you to create a personalized configuration in the "System" tab and then click on

Respect the name: es_systems_gamecube.cfg

You can then select your custom file from BatGui.exe on system tab.

[34] How do I add Cave Story to Retrobat?


__________________

MAJ: Since V5 of Retrobat, you can directly download Cave Story, in France or in English (like other games and demos) from the Retrobat store, here :





__________________



This tutorial concerns the version supported by Retroarch, with the core "NX ENGINE"
The NX ENGINE EVO version does not work with Retroarch but like a classic Windows PC game, so to add it to Retrobat see FAQ n°1.

To add the Cave Story game Retroarch version (in English) you can download it directly from RetroArch, accessible from the system menu "RETROBAT":

MAIN MENU > ONLINE UPDATER > Content Downloader


The downloaded "Cave Story" folder can be found in \emulators\retroarch\downloads\


Place the folder Cave Story (en) in the \roms\cavestory folder


Then run RetroBat and in the System "CAVE STORY" (or "PORTS" if you have not ungrouped the systems in the collection options) you must hide the files DoConfig and OrgView:



and




Then SAVE.

[35] MSVCP140.dll and VCRUNTIME140.dll missing, what to do?

You just have installed retrobat but at launch you get a message telling you *.dll files are missing.

To fix this issue, you should download and install these 2 files :

- visual-c-redistributable-runtimes-all-in-one_Dec_2021.zip (uncompress it into a folder and launch "install_all.bat" )


- dxwebsetup.exe

Then reboot your computer.

[36] What if the Retrobat display appears green?





You just installed Retrobat, start Retrobat.exe, and here comes the drama  :





Hopefully, there is a solution that most of the time avoids this problem.
Go to Windows display settings (right click on your desktop) :





And change the scale to 100%

[37] How to add your STEAM games simply in RETROBAT with Batgui?




It is possible to add games from your Steam library to Retrobat, in order to centralize all launchers in the same place.

To do this, you must make your Steam profile public first.

Open your Steam application, and click on your nickname
In the window that opens, click on "edit profile"




Then, go to the "Privacy Settings" menu on the left,
and change your profile to "Public"





Then move to the "General" menu, and check or fill-in the custom url
A relatively long time may be necessary for Steam to activate the public profile






The others steps have to be done from BatGui.exe, available at the root of your Retrobat installation.
Start BatGui.exe,(update it if it asks for it)  then go to the "Steam" tab
fill-in your Steam username, then click on the "Load Steam Game" button
(if Steam has not yet activated your public profile, games will not display. You may need to wait up to 30 minutes the 1st time)






Then select from the list of your Steam games the games you want to appear
Check the box if you want to close Steam when closing the game
Finally press the "generate .bat in /roms/windows" button to start the necessary files creation.





NB :
BatGui succeed to find 90% of the executables names used to launch games. But it's not always the case.
If the "exe" column is empty, you must manually enter the name of the executable.

[38]Why I get the message "Retrobat is free software[...]" every time Retrobat is started?


When Retrobat starts for the first time, you can observe the following message :




Ce message n'apparaît qu'une seule fois, mais chez certains utilisateurs, ce message apparait à chaque lancement de Retrobat.

This is not normal behavior.


To fix this bug, you have to delete a file.

On your Windows file explorer, type this line:

Code:

%AppData%\RetroBat

and validate with "Enter":




The folder C:\Users\**username**\AppData\Roaming\RetroBat should open, containing the file user.key , delete this file, and relaunch Retrobat.
The message should appear again for the last time, and should not appear on subsequent launches.

[39][V5] How-to make run games based on Hypseus emulator ?

Hypseus is a fork of Daphne which allows, among other things, to run SINGE games (including American Laser Game games).
In order to operate these systems, a specific procedure is required.

[40][V5] How-to use MEGA-BEZELS ?

Retrobat V5 integrate Duimon's Mega-Bezels

They are high quality bezels for Retroarch cores, with shaders simulating screen reflection.
As graphical effects requires some graphical ressources, Mega-Bezels can be activated with Vulkan drivers only.

[41][V5] How-to use the Wiimote Gun function ?

Within the 5th version of Retrobat, a software that allow the use of the Wiimote as a mouse have been added
This should make lightgun playing with a Wiimote a lot easier.

[42][V5] Make the message "DOKAN is required and not installed" disappear on emulators start

Some emulators (like CxBx Reloaded), mount games on a virtual support.
But to do so, Retrobat uses external componants, like Dokan

IF Dokan isn't installed, you will see the following message :




To avoid this message, download Dokan

Install it, then start Retrobat again.

[43] How to leave a game ?

To leave a game started from RetroBat you have to push the HOTKEY button and press START at the same time.

Some pads are already configured in RetroBat, that is why you might not know which button is used as HOTKEY.

As mentionned in the manual included in RetroBat (see FAQ n°8 ), it is HIGHLY RECOMMENDED to map the HOTKEY button to the SELECT button of your pad (BACK on a Xbox360 pad).



The exemple above represent the mapping for a Xbox 360 controller.
The button 6, that correspond to the BACK button of the pad, is mapped to SELECT and also HOTKEY.




Indeed, if you use the button GUIDE/SHARE of your box360/ONE pad, or any similar button on another controllers, there is a risk that it doesn't work as expected to leave a game.

You have the possibility, only for systems managed by Retoarch (Libretro), to activate an option that allows you to quit by doing HOTKEY + (START X2)
This option is mainly used for some games that require Select + Start to do a cheat code.
