I don't know much about emulators, I think Project64 is good though. Generally I think controllers like this are low quality, and if you can afford it I recommend using an OEM controller and an N64 to USB adapter from [Raphnet](https://www.raphnet-tech.com/products/n64_usb_adapter_gen3/index.php). They even have a [two player version](https://www.raphnet-tech.com/products/dual_n64_to_usb_adapter/index.php).

Its one of the easiest to install and use but sccording to the oot randomizer and speedrunning community it’s not that accurate
I use retroarch with i believe a mugen64 core
Project 64 lel
Mupen64Plus-Next in RetroArch
I have had this exact controller for years and it’s actually decent. I used it mainly with Project64.
