how to make a choice of different versions of the emulator?

I have two different versions of ryujinx emulators, I tried to add the second emulator, but when I try to launch it, an error occurs that the emulator is not found.

It seems that adding new emulators is impossible, but I just want to launch another version. Is it possible to somehow make it so that you can choose which version of the emulator to launch in the menu?

Hello

And the question : why having 2 versions of Ryujinx ?

because I added an additional line for the new emulator to the config, I also made a new folder, and wrote all the paths in the additional files. but nothing worked, and the program crashes on an error

Code:

there are many version of ryujinx but the latest one is unstable in some games so i would like to have two versions of this emulator one latest for some games one previously created with lower version for others

Hello,

This is not possible as RetroBat links an emulator to a generator in its core program.
So ryujinx-latest ==> does not exist in our code.

I would be very grateful if you added the ability to create emulators of different versions by referring to the main emulator generator (for example, by specifying an optional parameter for generation).

Code:

<command>"%HOME%\emulatorLauncher.exe" -gameinfo %GAMEINFOXML% %CONTROLLERSCONFIG% -system %SYSTEM% -emulator %EMULATOR% -core %CORE% -rom %ROM%</command>
   <emulators>
     <emulator name="ryujinx"/>
     <emulator parent="ryujinx" name="ryujinx-latest"/>
     <emulator name="sudachi"/>
     <emulator name="suyu"/>
     <emulator name="yuzu"/>
     <emulator name="yuzu-early-access"/>
   </emulators>

or some special parameters for the core

Code:

<command>"%HOME%\emulatorLauncher.exe" -gameinfo %GAMEINFOXML% %CONTROLLERSCONFIG% -system %SYSTEM% -emulator %EMULATOR% -core %CORE% -rom %ROM%</command>
   <emulators>
     <emulator name="ryujinx"/>
            <cores>
                <core>ryujinx</core>
                <core>ryujinx-latest</core>
           </cores>
     <emulator name="sudachi"/>
     <emulator name="suyu"/>
     <emulator name="yuzu"/>
     <emulator name="yuzu-early-access"/>
   </emulators>

In general, I dug into the code and realized that I only need to correct two lines of code to use the desired generator

Program.cs

Code:


            string emulatorName = SystemConfig["emulator"].Split('_')[0];
            Generator generator = generators.Where(g => g.Key == emulatorName).Select(g => g.Value()).FirstOrDefault();


I just made a small check to filter up to the "_" symbol, thereby simply ignoring the remaining symbols

I also corrected the code in the Ryujinx.Generator.cs so that it generates a new path (similar to Yuzu)
Ryujinx.Generator.cs

Code:

           string path = AppConfig.GetFullPath(emulator.Replace("_", " "));
            if (string.IsNullOrEmpty(path) && emulator.Contains("-"))
                path = AppConfig.GetFullPath(emulator);

            // string path = AppConfig.GetFullPath("ryujinx");
            // if (!Directory.Exists(path))
            //    return null;

I posted the compiled file on GitHub
