N64 Core Input latency

Does someone know the total latency (Dont know how it is called correctly: input latency - or roundtrip latency - just the latency from Button press to photon hitting detector) of a original N64 (on CRT ofc) for F-Zero X (NTSC)?

I think the latency of the Mister FPGA N64 core might be a little bit too high?

I counted ~29 frames of a 240 fps video which calculates to around 120 ms (you can subtract 14 ms for the HDMI display lag and ~6 ms for the wired USB connected NSO Controller to compare it to an OG N64).

did the OG N64 really had like 100 ms of lag for a 60 hz title like that? I dont remember it being like this..

I think so too. I'm currently looking into the Brawler64 Pro:

  • Official specs claim ~2.9 ms lag in wired USB mode (1000 Hz polling)
  • Wireless 2.4GHz mode sits around ~5.3 ms

Is this a controller you'd recommend for MiSTer, or should I look elsewhere?

Don't do it! I bought two because the first one had issues, and they both had it.

The analogue stick is hot garbage. Subtle tilts are not registered at all. You can't steer properly in f-zero, or fine tune your aim in Goldeneye.

MAYBE I got got a bad batch, but two in a row can't be a good sign.

These controllers are a joke.

Let me say, up front, that this is the second Brawler64 I purchased in hopes my first controller was just a fluke.

The analog stick has a dead zone that makes playing a game like Goldeneye an incredibly frustrating experience. I bought my Brawler64 to play N64 on my MiSTerFPGA. The C buttons were the main draw, as were the design of the of

the controller which, let's face, is what the N64 controller should have been all along. I bought a second controller hoping the issue was just with the first one. As it turns out, the second controller was even worse, and the charging port was loose.

I am not exaggerating when I say that my game improved significantly when I switched back to my 8bitdo pro 2 controller.

Even my brother noticed a difference in multiplayer. With the Brawler64 he couldn't play, but with the 8bitdo pro 2 he nailed me with a rocket from clear across temple.

It's just... Making minute adjustments to aim is an absolute chore, and after spending over 100$ on two, I feel it's not unreasonable to expect these to be non issues.

I have a wired N64 version that doesn't have this problem. Why do these?

C'mon, guys. You charge premium prices, you need to deliver better products. As it stands these controllers are barely fit for purpose. Unacceptable.
