Dragonrise USB (Zero Delay Encoder)

[PanosPl]

That's a general bug that affects RetroPie too.

The ZeroDealy encoder based joysticks do not go up&down due to an error that can be fixed only by replacing strings using a hexadecimal editor.

See here: raspberrypi/linux#1527
and here: https://retropie.org.uk/forum/topic/1686/up-down-y-axis-not-working-in-3-8/53 (proposes the fix)

Since DietPi and Amiberry are more flexible, is there a chance that this fix be incorporated in the build?

Thank you

We could fix this, if it doesn't affect other joysticks. But won't it get overwritten with the next firmware update?

[PanosPl]

I would appreciated if you could give it a try. It is the wider used joystick encoder (due to its price)

Have you verified this is still a problem with the latest kernel version? It's moved up since 4.4.11 which is referenced in the links.

Too technical for me Dimitris. I can see that the RetroPie thread is still going strong so I guess no solution yet.
