Does game genie work with muilti game cartridges for snes?

I contacted the maker of one and he said it possibly could work. But he isn't sure cause he doesn't have game genie. Anyone with a multi game cartridge can see if it works for the snes?

I wonder if it would work with a sd2snes also if it's allowed here.

I have a super nt now and I can confirm with the newest firmware with cheat option it works with my flash cart and fx muilticart with cheats since the cheat menu is in real time and can be turned on and off wile playing a game.
