Thanks you two for the answers! Good to know that both seem to be acceptable.

Hello, Super Metroid speedrunning community!

So, I'm currently using an iBuffalo Snes controller with emulator to practice this game. I haven't submitted any runs yet. The rules states:

" The input method of systems must also simulate the original hardware. Original SFC/SNES controllers, Wii Classic Controllers, SNES Classic Controllers, and USB controllers are allowed. Keyboard is allowed if and only if the player is using a computer emulator.

Any controller with functions that do not exist on the originally manufactured controller (A, B, X, Y, L, R, Start, Select, Up/Down/Left/Right) - such as macros and turbo - is prohibited. This includes any controller with such functionality built in, regardless of manufacturer. Basically, any external hardware that creates a situation which cannot be replicated with out-of-the-box hardware is prohibited.

Similarly, remapping controls in a typically impossible method - such as assigning Angle Up, Angle Down, Start, or Select to a 'face' button (A/B/X/Y on the original controller) - is prohibited. "

Does this mean that I can't use the iBuffalo Snes controller since it has turbo functions, even though I don't use those functions? And if that's not allowed, is the PS4 controller allowed, assuming I didn't set up more than one "l" button and one "r" button and otherwise mapped the buttons correctly?
