I gave up trying to find a good N64 emulator, and just got a flash cart.
I was using RMG for a while, but it eventually stopped working right for no reason. P64 used to be my go to back in the day, but somehow it seems to work worse than it did a decade ago, at least for me.
Oddly enough, and I don't want to sound like a shill here, but the only stable N64 emulation I've used was the one on switch online, which obviously means little to anyone without the hardware and a premium subscription.
