@acris I will create a support file tomorrow and give you the link. The N64 controllers work perfectly in ES and in-game. Only the NES and SNES have issues (They use a different adapter than the N64 controllers. Maybe this can be a problem.
Do you mean the material of the box itself?
So far I haven't changed anything in recalbox.conf. Should I?
do you use mayflash adapter or other ? link ?
may be you need usbhid quirk
@acris This one for NES/SNES:

And this one for N64:

I need your archive (recalbox-support.sh)
In theory I think you need usb quirks or others things udev rules.
in recalbox.conf you can tested to switch auto driver in sdl2 or udev.
## If you don't have issues with your controllers, let auto global.inputdriver=auto
reboot you raspberry if you modifed
sorry for my english.
@acris Thank you for your help. I will do the modifications and the support file tomorrow amd let you know
Your english is quite good, mine is not really better, haha 
@acris
I have changed global.inputdriver=auto to sdl2 and udev. Same behaviour, SNES and NES controller still only work in ES.
Here are my support.sh files:
Only adapterbox connected to recalbox (no controllers connected to box):

SNES controller connected to adapterbox (Works fine in ES):

@lackyluuk
try this idea :
mount -o remount,rw /
edit this file : /etc/modprobe.d./usbhid.conf
add theses lines at the end :
#raphnet.net 4nes4snes v1.5 options usbhid quirks=0x289b:0x0003:0x040
save and reboot your raspberry.
Try SNES gamepad.
but I think theses adapters need patch kernel.
@acris
Thanks for your help. Unfortunately it does not work. I saw that the 4NES4SNES adapter is already in the /usbhid.conf file.
Could it be possible that the new version v1.5 is the problem?
Is there anything else I could try to figure out?
@lackyluuk
not it s another
your id vendor and id product are differents, you need to add my informations and try if you didn t do it.
oh not raphnet need a kernel patch too
@acris yes I have tried your info, but no luck 
i think kernel patch is missing in recalbox 4.1
Ni idea if it requires a patch to the kernel, i don't think so as it works fine in es, right ?
@Substring yes, in ES it does what it should. But no response at all in a game. This only occurs with the 4NES4SNES adapter. The one for N64 works fine.
I have connected these two adapters with a small usb hub.
@lackyluuk ok, this is what you should do :
Give a try to https://github.com/recalbox/recalbox-os/issues/1244#issuecomment-2981808465 because it has an updated retroarch version, i know i had to rewrite 1 patch regarding inputs, so maybe that would do.
Still, if it works in ES, it means it works with SDL and linux kernel, so that is a retroarch problem. You could eventually try some non retroarch emulators with these pads (mupen scummvm, advancemame, reicast)
@Substring thanks a lot! I will try these points and give a feedback then.
@Substring I have found some patches for this problem I think. They are from raphnet itself. Do you think this could work?
http://www.raphnet-tech.com/support/retropie/
(And we should let him know about recalbox, haha ;))
@lackyluuk 4.4 kernel doesn't seem to require these patches. Anyway please test what I suggested. The quriks are not necessary (or were they already applied when you submitted your support archive ?).
So, still, i believe it's a RA problem.
@Substring Yes of course, I will test it tonight when I am home.
The quirks from @acris were not implemented when I created the support archives.
Yes, the quirks from the second point are only for pre-4.2 kernel. But do you think that the first point "Issue with initial values" (the 3 patches) is also covered through the updated kernel?

@lackyluuk your controller does work with ES, so i'd say yes. I'll have a look at the kernel code though
Results:
evtest works super fine
sdl2-jstest works fine as well
Config in retroarch not successful
TADAA: I have tested Mupen and the SNES pad worked even in-game... so definitely a retroarch problem
Installed the unofficial new version with retroarch 1.5 --> no success
Maybe let them know about this 4NES4SNES v1.5 adapter?
..pheww..
