How to make a choice of different versions of the emulator?!

[Goodfeat]

This small fix allows you to add multiple versions of the same emulator (this was tested by ryujinx)

you need to create a folder with the same name as the original emulator (for example, for ryujinx you need to create a folder, for example ryujinx_latest)
add es_systems.cfg a new emulator with the same name and make a new config for the new emulator in es_features.cfg

Program.cs

            string emulatorName = SystemConfig["emulator"].Split('_')[0]; // <--- fix
            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

 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;
