Last time I used my iPac2, I was still on Recalbox 6.x. Meanwhile, I had my devices stowed away, and now I reassembled my control panel just to verify if they work. I checked again with 7.1.1, and I can confirm the iPac2 does not work anymore. It behaves like a plain simple keyboard. My iPac2 controller is very old, pre-2015, no fancy firmware updates to check, but has always worked fine.
D**n. Time to try another retrogaming distro.
@SmashDde , what you describe seems to be correct.
Check if the device listing shows more than one entry/name. If yes, you must try them all.
I used this method to setup my iPac2, and I remember only one of the strings worked.
@Bkg2k I have 3 MAME subfolders, and these do not show in the Arcade virtual system... Only in the MAME folder.
@Zing I'm using a RPi4 booting from a SD card, ROMs and other system stuff stored in a 32 GB USB stick, fresh install of RB 7.1.1.
When using a MAME folder without any subfolders, the Arcade virtual system shows these ROMs as expected, together with FBNeo (and NEO-GEO, if enabled) so this problem looks like an unforeseen consequence of using subfolders... There is an option to display subfoder contents when in the Arcade menu, but it didn't help.
Nevermind about the Naomi ROMs, the documentation only mentions MAME and FB in the Arcade virtual system, so it probably won't apply to other cores/emulators.
@SmashDde You're welcome. I know what you mean, I have another keyboard encoder and these things are really a pain in the a** to get configured properly. Sometimes it's just a tiny forgotten detail that makes them work, so we keep trying again and again...
But in our particular cases, it looks like nothing can be done without help of the devs. The ArcadeForge encoders are "asking" to be fixed since Recalbox 4.0, I think, but because these are not mass-produced commercial products, widely available and with a lot of users, not much information can be found and they do not attract that much interest 
@SmashDde I've just finished testing the encoder with 7.1.1, paying extra attention to how the inputs behave inside EmulationStation.
When in gamepad mode, the encoder works, but not as smoothly as it should. For each 10 vertical (up/down) stick movements, there are one/two movements which will register two inputs. It's somewhat random, and very annoying. After launching a game, the controls work quite well... it's somewhat difficult to say if the double input is present or not. Maybe it depends on the game.
When in keyboard encoder mode, the vertical movements will always register two inputs, and only one of the eight buttons is working. Configuring the encoder manually as per the tutorial instructions has no effect at all. Therefore, completely useless.
In my RB setup, I have two Libretto MAME cores and AdvanceMAME, with the respective ROMs organised as subfolders. Additionally, I also have FBNeo and some NAOMI and Atomiswave ROMs. Everything working perfectly.
However, if I enable the Arcade virtual system, only the FBNeo ROMs are shown.
What am I doing wrong?
PS: Just updated to 7.1.1
I have an Arcade Forge Dual Strike encoder, and I can confirm this is a real problem in RB. The joystick movements register twice, unless you tap it really quickly. In my case, the encoder is set up as a standard 8 button gamepad (not as a keyboard), and it's possible, but not easy, to configure the directions correctly. The 8 buttons are working fine.
Btw, the encoder works perfectly under Windows or Lakka, so it's not a hardware problem. This looks like some timing issue in the 4 directions.
@neo207 , I've read somewhere that Sega ST-V games (Cotton 2, Cotton Boomerang, Radiant Silvergun and some others) are playable using a RPi4 with AdvanceMAME.
AdvanceMAME was not working correctly with RB 7.01, but it's supposed to be fixed now with RB 7.1. I have not upgraded from 7.0.1yet, so I cannot confirm.
@thomasfou
So there are more gamepads with the same problem...
If I remember correctly, the WiFi SSID and password are stored as plain text in the recalbox.conf file. You can just edit that file directly by inserting the SD card in any PC to get the WiFi working.
Hope this helps...
@Zing
I'm using a fresh 7.0.1 installation, nothing was imported from any 6.0. When the gamepad is plugged, RB 7.0.1 detects it and pops a message in the upper-right corner, saying it's "ready to play".
Well, it is not... Only the buttons are working in ES, but not the D-pad. The gamepad must be configured manually for 7.0.x, and then it will work fine. But for 6.0 and previous releases, it was automatically detected, 100% configured and ready to use right after being plugged. Indeed, this gamepad is listed in the compatibility list as working, which it is not exactly the case anymore.
Not a serious issue, but something is wrong or missing somewhere in the 7.0.x, configuration files, right?
Same gamepad, different problem.
Hi
The iBuffalo SNES Classic USB Gamepad was working out-of-the-box with Recalbox 6.0 and previous releases.
With 7.0x, we plug it and... all six buttons are OK, but the D-pad is not recognised and does not work anymore. I had to plug an USB keyboard and manually configure the gamepad to get its D-pad back.
I guess someone forgot mapping the D-pad? Is there something I can do to fix the problem myself?
My thanks to the RB team for all their efforts in putting together this great piece of software.

@smashdde, good to know!
From my experience, the troubles with the encoders have always been due to tiny, f***ing, missed details, from taking wrong shortcuts, and so on... 8-P

Hi @SmashDde
I read through your posts in the other thread, but I have no idea how to help you. In my case, getting the ipac2 to work with 6.0 was just a matter of creating the correct dummy file and remapping the P1 controller in RecalBox, using the standard procedure inside EmulationStation (pressing a button to detect, then filling the remap table). Not much to describe here.
For the record, I also own a DualStrike v3 single player encoder, from ArcadeForge, and it also works fine with Recalbox, using the same X-Arcade "driver".
I remember having some problems with "disappearing" buttons, but these were due to bad wiring/soldering/terminal contacts near the iPac2. After checking my wires, I retested the encoder in Windows, using a proper keyboard tester utility, and made myself sure the encoder, wiring, P1/P2 buttons and sticks really worked as intended.
Once hardware problems are totally sorted out, if you still have your encoder detected as keyboard, then the dummy file may be incorrect. In my case, I had two options for the filename, but only one worked - see the mini HowTo for details.
If this still does not work, the only conclusion is that we have a encoder incompatibility with Recalbox... that would be really bad luck

Confirmed, it works exactly as in 18.xx.xx and 4.x .
I got confused because my standard gamepad was detected "as is" and EmulationStation immediately shows it in the list of available controllers. But for the IPAC2, after going through the creation of the fake files, we still need to invoke and conclude the remapping in order for the two IPAC2 built-in controllers to be displayed in that same list!...

I went through the mini-howto again, and tested with evtest . It detected the two sets of sticks+buttons provided by Ipac2, each one registering separately.
It's just EmulationStation which does not detect two X-Arcade controls out of the box, as it did before 6.0. It looks like now we have to manually remap the two Ipac2 sticks+buttons inside EmulationStation, in order for these to get registered properly.
Has anyone managed to get an Ipac2 working with v6.0 ?
After some struggle configuring version 4.x, some two years ago (see this topic), I got my Ipac2 working perfectly.
It also worked fine with versions 18xxxx.
But once moved to v6.0 and after going again through the same tutorial, it looks like the new version of Recalbox broke something, as now my Ipac2 is not detected anymore. Nothing is visible/detected inside EmulationStation.
Any ideas?

@voljega , I have a similar problem... I need to bring my RPi2 console near my home router to be able to SSH inside. I've been trying to avoid all the pain of going back and forth loaded with a wooden crate every time something breaks inside.
My idea was to use a Windows laptop with WiFi + ICS + small cross-over ethernet cable and connect to the RPi. Unfortunately, for some reason Recalbox is unable to get an IP address via DHCP when using Windows+ICS. That only works with a proper hardware router. However, this is matter for a separate troubleshooting thread...
@Substring , YOU'RE MY HERO! 
Now, maybe someone should touch up the text in the tutorial. People may be using the wrong filename, because they see the -if01- in the provided example.
@luke, check these last posts by Substring and then try to change the file yourself, it should fix your IPAC.
