I'd like to suggest using the official BSNES emulator from Byuu which is just the SNES component of Higan broken out into its own thing, it's just as accurate as Higan but simplified in its use: https://byuu.org/emulation/bsnes/
Just dump all the special chips in the firmware folder of the BSNES install folder, it loads games straight up instead of doing the whole icarus stuff.
Or you can use the Higan core in Retroarch if you like.
