It works perfectly on a real Everdrive N8 and N8 Pro. I've tested it on 3 N8 Pros and 1 N8. Tested on both NES and Famicom versions. I tested all Everdrives in an Analogue Nt Mini Noir. I have had no issues at all. It even runs from the flash card of the Analogue Mini Noir running the jailbrake firmware. Is your flash cart a genuine Everdrive or a clone copy of the Everdrive? It's possible the clones of the N8 won't work.
