two versions RPCS3 PS3

Hello friends!
I'm trying to use two different versions of the PS3 RPCS3 emulator. I do this because I have an old version with several games already configured.

My question is which argument to use to create a new emulator in es_system.cfg?

Below is the code I used and how I did it to distinguish the emulator versions:

es_system.cfg:

<system>
   <name>ps3</name>
   <fullname>Playstation 3</fullname>
   <manufacturer>Sony</manufacturer>
   <release>2006</release>
   <hardware>console</hardware>
   <path>~\..\roms\ps3</path>
   <extension>.m3u .M3U</extension>
   <command>"%HOME%\emulatorLauncher.exe" %CONTROLLERSCONFIG% -system %SYSTEM% -emulator %EMULATOR% -core %CORE% -rom %ROM%</command>
   <emulators>
     <emulator name="rpcs3"/>
 <emulator name="rpcs3_bd" command="\RetroBat\emulators\Rpcs3_BD\rpcs3.exe %ROM%"/>
   </emulators>
   <platform>ps3</platform>
   <theme>ps3</theme>
 </system>


extension m3u:

\RetroBat\rpcs3_bd\dev_hdd0\disc\BLUS31203\PS3_GAME\USRDIR\EBOOT.BIN

Hello,

We do not support custom versions of Retrobat.

But why don't you update your version?

Hello.

BTW, it make nonsense to create another install, when you can move your folders in the Retrobat installation (or point m3u elsewhere)
