Super Game Boy on Android

[BanditTech]

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 mercury 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.
