Firmware usb2pce-2023-06-14 and greater break compatibility with 8bitdo PCE controllers #8

Firmware usb2pce-2023-06-14 and usb2pce-2023-06-21 break compatibility with 8bitdo PCE controllers. Specifically, dpad Up and dpad Left no longer work. There may be other issues too but this is as much as I could test having no dpad left or up. Verified using two different 8bitdo PCE controllers. Reverted back to the June 8 firmware and it's working again.

Thanks so much for bringing this to my attention. This is the last controller I wanted to break support for. LOL

Good news is that I traced the issue down and fixed it. Appears to be related to the introduction of Switch controller support. Some how the receiver goes into Switch mode now that I support it and the third-party switch mode had a bug related to the conversion from analog values to dpad directions.

The update with the fix will be live shortly. But a work-around in the meantime is making sure your controller itself is set to default dpad mode rather than simulated left analog.

PCE Default Dpad Mode:

Hold SELECT + UP on the controller for about five seconds. You should see the LED flash and then the dpad will now send normal dpad buttons.

OMG! So my controller is in some weird mode? Sheesh I had no idea. Don’t even know how it got that way. Thanks very much for the fix 😊

This issue should be resolved in the latest release.
