Scenario, the 15ms latency from point 1 adds to the 10ms, totalling 25ms. Depending on the timing, if the adapter learnsĪbout the button press right after the USB poll took place, the computer won't know about it for another 10ms.

The USB poll interval: For an USB low speed device, the minimum interval is 10ms.

But it also means that if you push fire 1ms after the poll, the adapter will only This makes sense as it mimics what most gamesĭo in polling the controller once per video frame.

The controller poll interval: Adapters commonly poll controllers at 16ms intervals.

There are two main contributors to latency: This means that to send the event, the adapter actually has to wait until the next USB poll.

But USB devices are also polled by the PC at a fixed interval.

When a change is detected, the adapter sends an event to the PC.

At a fixed interval, the adapter polls the controller to detect state changes (buttons, axis, etc).

If expressed with words, an adapter works like this: Let's look at why and how it happens and what Please let me know of any additional controllers you had the chance to test.įor responsive controls and high performance gaming, high adapter latency is extremely undesirable. Note that even if a controller is not listed above, it is most likely supported. Standard (Japan import, extra long cable) Here is a list of tested controllers/adapters:

Stability improvements (prevent a potential buffer overflows when receiving).

Automatically perform center calibration when connecting a gamecube controller.

Adjust Gamecube/N64 wire protocol timing (Fixes Mad Catz controller).

Add a test rumble command (for GUI tool, or for simple rumble control).

Now it works fine in openEMU.īugfix: Fix vibration code for x360ce (Vibration would turn on and never stop)

Change gamecube trigger HID usage (Slider became Z).

Implement N64-only and GC-only personalities (Different USB product ID and device name).

Do not install older versions on dual-controller adapters. Version 3.3.x series: Dual controller support. Fix the connected-controller display feature in dual controller mode.New IO request for even lower latency when using the raphnetraw plugins.

Implement a feature to let the adapter manager query the feature set of the current firmware.Internal changes to workaround a presumed Windows bug (Joystick ID confusion where the second controller stops working or gives an error in the Game controller test dialog).Add a disable analog triggers mode for Gamecube controllers.Add a triggers as buttons mode for Gamecube controllers.Fix never-stopping vibration issues (Dolphin).Shrink and soldering the AVR programmer wires to the right places.

Of course, it will always be possible to upgrade an adapter by cutting open the heat Ok, ok, when I say impossible, I mean for the average user who bought a ready madeĪdapter from me. Native USB support simply removes the restrictions imposed by the software-only USB implementation that wasįormally used, to the benefit of higher performance and opening up of new possibilities. 6ms worst case)Ī complete redesign of the electronics is what enables all those improvements.

Firmware updates not possible (or very difficult).

Why a new version you ask? Because it was possible to do even better. Complete adapter This is the third generation of my N64/Gamecube controller to USB.
