7zip open as Directory RetroArch 1.2 cmd

I noticed that 1.2 has the ability to open 7zip files as a “directory” to select the appropriate file extension for the core, My question is: Anyway to do this via command line? Possibly something like this?

.\Emulators\RetroArch\retroarch.exe -L .\Emulators\RetroArch\cores\bsnes_balanced_libretro.dll “ROM.7z\ROM.SFC”

I don’t think that’s exposed via the command line in any fashion, no.

Try rom.7z#rom.ext

Try this one…7-Zip 9.20
