How do u get a snes input veiwer like Project64 spy?

It does not work.What about Emulators?

Well of course it won’t work, NintendoSpy is for real hardware and doesn’t have a way to hook into emulators that I know of (maybe it does and I never knew about it).

I know some NES emulators have a setting you can enable to show the inputs on a built in viewer, but I’m not sure about SNES. What emulator are you using?

Snes9x and zsnes

NintendoSpy supports both generic PC controllers, and SNES (Assuming you tap into the cable, and have a microcontroller to run the software), as well as some others.

So you can use an emulator, and NintendoSpy to capture your PC Controller inputs. I do it with a USB SNES controller while running on emu.
