@seanr8 I'm having the exact same issue. I'm using the Huijia N64 adapter and the Project Venom N64 controller (from Amazon). Did you get anywhere with configuring this correctly and preventing the extra button presses?

Thanks

I apologize for reviving an old post but this post was perfectly on topic for what I am looking for. I have been scouring the internet for the past three days, and editing config files over and over with no luck. I also have the Mayflash with original n64 controller. With your config files, I was finally able to get actual input in roms with the controller. I can't tell you how excited I was and I can't thank you enough. However, I am having some additional in rom issues. For example in Mario, he walks instead of runs even with the joystick at full tilt. Any ideas on how to fix these issues? Did you run into these type of issues?
