up & down (y-axis) not working in 3.8

Fabpie

Just discovered that with another pad with USB pad driver, daphne works.
So it seems it is a hid-dr.ko driver problem or something else.
Hope this could be a clue for you!
thanks

@Fabpie Thanks. It does work with another gamepad. I tested that. I got the up and down to work after making changes to the driver. Now left and right does not work. Very odd!!!!

Fabpie

it does not recognize the 0 axis, 30 in HEX. The strange thing is that works with "Y" axis and actually look at the driver, this make sense. I mean once you switch from 33 ("Rx" based to the Joystick scheme) to 31 ("Y" based to the Joystick scheme) to fix "Y" as above, solvethe issue as should be. So for "X" it looks like the "0" value is not really appreciated.
I hope there is a solution to fix this. So frustrating ;)

Based on my internet readings The issues cuold be:

Debian Bug report logs - #785606
HID support broken for some devices (incl. DragonRise USB joystick)
Driver problem (hid-dr.ko)
Other Kernel issues
I've also found articles talking about ways to PATCH this problem but, onestly, I can't manage to figure it out.

Can we just tell the joystick to use another driver and emuate an USB GAMEPAD?
Can we fix the firmware?

This is all I basically have in my mind / dreams ;) . Really hope to find out a solution. As Daphne would say... Save Me! ;)

Thanks. Also, I edited the file in Windows. I was able to copy and past the changed file into the proper directories (after a backup of the file just in case) by manually editing /etc/ssh/sshd_config. I changed the PermitRootLogin to yes and rebooted. I was able to ssh and FTP in as root, giving me the permissions to overwrite the files. So do you think there is a fix for this issue? Dragon's Lair is not playable with the Dragonrise with it!

Fabpie

I'm wondering if anyone here can explain if there is a solution, at least how to patch this issue.
Very sad about it.

So doing what I did got the Y axis to work in Daphne, but took out a bunch of other joystick functions. And it still didn't fix the X axis in Daphne. I had to re-image my entire system! This is a bad issue for sure.

Fabpie

Even stranger. I will try by patching it. But it's quite tricky ;)

Fabpie

I've found this recent patch that looks like it would be helpful for this issue.
Only one little / big problem for me.
No idea in how to patch it ;)
I've tried few things but i couldn't been able to patch it.

Does anybody have suggestions?

@Fabpie thanks for sending. I have no idea what it means however. If u ask me, our best bet is to find another encoder. Bummer!

Fabpie

I will fight for Daphne. I love that game since '83. It has to work ;)

retropiepghguy

@Fabpie I want it to work. But that "fix" blew up my test machine. The Dragonrise is amazing except for this issue.

Fabpie

Solved this issue by using an hardware way! It is a bit "analogic" but nice and functional.
I'm basically building an arcade cabinet so just adding a button I fix it.

That's how:

I'm using a zero delay USB encoder that uses his partner in crime "Dragonrise" (driver hid-dr.ko).
On this encoder there is a "MODE" input that switches X,Y,Z,Rx,Ry, to Hat0x and Hat0y.
I quicly connected a button to this "MODE" input.
When I play daphne i just need to press it and that will pass to daphne new types of axis (Hat0x, Hat0y).
At this point due to my personal experiences what happens is that daphne recognize the joystick in both cases but it hasn't able to understand the X axis due to the driver hid-dr.ko (This needs a fix anyway), instead it is able to auto map the stick with this new axis that maybe are far from conflict with something else.

I'm very very happy even if is a bit a DIY solution and it will cost a special button only for daphne and specially for my arcade cab.

For now I'm fine with this solutio but as i said it would be great to add a "not analogic" fix ;)

if you have a backup of the hid-dr.ko should solve your problem. I'm sorry for your buttons, I hope hasn't been my fault. For this thanks again for your research about this issue.

Tonight I save Daphne !!!

@Fabpie My god!!! Nice work!!!!!!

retropiepghguy

And let me get this straight. Amazing work BTW!!!! I mean really!!! Wow. The "mode" button is right next to the pin-out for the "left" button. You wire a button to that. Just before firing up Dragon's Lair, you hit that button? That's it? And did you still have to make that goofy change to the hid-dr.ko driver? Being able to use that butotn without the HEX fix to the drivers would be even more amazing!!! Please advise!!!!!

retropiepghguy

It's brilliant. I just tested it. No driver change needed. Wow. And the button can be pressed at anytime. Wow. Amazing work!!!!!

Fabpie

Very
happy it works for you as well !
Is a nice fix... I think verybody who loves Daphne / lasergames should consider this way.
When digital meets analog ;)

Hi all, thanks for all suggestions here, my issue only happens so far with mame4all, I also have the Dragonrise USB controller, I did setup properly, it was working on retropie 3.4 on the UI and all emulators. Since I updated the code I started having the issue, where up & down won't work but to me only happens on mame4all, the other nes, snes and n64 all work ok to me (I didn't try on other emulators). It also works ok on the UI. I also installed a clean retropie 4.1 and still having the same issue.

I tried all your suggestions, the mode button does change the joystick mode yes but doesn't help me, and changing the binary files made my controller unusable :'(

I'm lost really not sure what else to do, apart from try and install the old retropie 3.4, will do and post here if that fix temporary my issue.

Ok I can confirm that all works fine on retropie 3.4, I can enjoy my Dragonrise controller (I reused an old iCade cabinet), with mame4all, nes, snes and n64! I will stay on this version until this gets sorted, hope this can help anyone else.

jretropie

Does anyone updated 4.1? Does it need to hex edit again after the update?
