Super Game Boy android launching from command

I saw other threads open regarding the SGB but they are related to the PC. I have been able to get the SGB cartridge running inside BSNES performance on my shield tv. I am attempting to set up some way of launching the games directly through my frontend Hyperspin.

It says on the core wiki that it is only a PC thing but I have gotten it to launch a game and it is showing it load GB cartridge with the proper border. SO to be clear, the process I am using to get it to load is: I load content--> load SGB sfc file, and select mercury core --> go into quick menu and select super game boy --> load the gameboy game and then load the sfc file again --> game will launch but it doesnt run at full speed. I remember seeing in the core information that it will run better if launched from the command line.

I was hoping to get help with the syntax to launch from the command line.

cores/bsnes_performance_libretro_android.so "/storage/emulated/0/Hyperspin/Roms/Nintendo Super Game Boy/roms/SGB2.sfc" --subsystem sgb

Start with the Android core entry point named in the report: cores/bsnes_performance_libretro_android.so. Reproduce the SGB2.sfc launch flow on Shield TV and compare it with the documented command-line invocation and --subsystem sgb option. Done means confirming the supported syntax or identifying why this launch path does not run at full speed.
