Raphnet NES2USB Struggles

@mitu said in Raphnet NES2USB Struggles:

@hansolo77 Just a quick observation - from watching the previous topic and this new one - you didn't have to patch and install a new linux kernel.
The current Raspbian Jessie image - which RetroPie uses - already has a recent enough kernel (4.9.35) which should include the patches mentioned on the Raphnet support page (applied in kernel version 4.2.0).

See, I thought that was the case. But lastnight after performing the long kernel upgrade, the dreaded NORTHWEST DRIFT issue came back. So I rebuilt the kernel again with the included patches. The drift is gone, but the 2-device issue is still present. I don't know what I could be doing wrong. The process I'm using to update the kernel is documented here. Raphnet does have an additional patch, with a link to a forum post about it. I suspect I need to install that too, but when I tried to do that this morning (copy/paste into a .diff file) it gave me errors asking if I wanted to resume. Either way, it still doesn't work. Default (using the retropie-setup scripts) or Manually (using the other link from @obsidianspider).

@hansolo77 Have you heard of retrousb?

They have a few USB kits they sell to modify your original controller to USB.
Just a taught.

I have, and consdidered them at one point. But my thought was, why go with an inline USB adapater if I can use the existing plugs? If I wanted to go directly USB, I would have been ahead to just buy some USB NES controllers. In hindsight, the Raphnet adapter was probably not the best course of action. There are certainly other adapters I could have used out there. I was quick to buy that one when I first started my project because I didn't know any better, and had read reviews that said they worked. And honestly, they DO work. I have no problem with the adapter. I can control Player 1 and Player 2 out of the box right now. ES and RetroArch works with them. It's only in my specific special use case that I'm having the problem. It's because I want to be able to use them only as needed. For some odd reason, if I have them mapped in ES, RetroArch stops working the Xbox controller. If I switch it over to use that, then the NES controllers stop working. The only way to have BOTH is with XBOXDRV. Now I just need to figure out how to get the system to give me 2 devices instead of 1.

@hansolo77 I highly recommend people not to buy cheap Replica Nes/Snes/MS etcetera controllers. But then again I can see why you didn't want to open up your original controllers.

POTENTIAL UPDATE
I posted a request on a Facebook Group asking for assistance. Through a hopeful suggestion, somebody linked to a thread about a similar issue. In fact, the reply was the most hopeful. @JoargTheBard suggested that the solution is to add this to the /boot/cmdline.txt:

usbhid.quirks=0x289b:0x0002:0x040

The interesting thing here, is that it is "almost" what Raphnet's script is supposed to have, which I already added. However, their script adds this:

usbhid.quirks=0x289b:0x0002:0x40,0x289b:0x0003:0x40,0x1781:0x0a9d:0x40

There a couple of things I noticed here. First of all, the obvious thing is that the Raphnet addition is a LOT longer. The 2nd thing is the last bit of the "suggestion", where he has it as 0x040, Raphnet has it as 0x40. This got me thinking. @JoargTheBard also suggested looking up information on the "Xin-Mo Controller". I've never heard of that, but Googled it anyway. What I found was a page in the RetroPi Github that also says to use 0x040. The page also says what the various numbers are (Score!) such as Vendor ID and Product ID, as well as a command to locate them on MY device. Well I did it, and sure enough the codes match from the suggestion, Raphnet, and My device. The only difference is the 0x40 vs 0x040 bit (and the other stuff added to the rest of the Raphnet "patch"). I suspect those other codes, after the comma, are there to fix other Raphnet devices that might have the same problem.

THE FIX?
I'm going to try erasing all the stuff after the comma on my current /boot/cmdline.txt first to see if that solves the problem. If not, I will try changing to the 0x040. I have high hopes. I'm just to tired to mess with it tonight.

QUESTION TO THE MASSES
Is anybody familiar with what that 0x040 is? Is it documented somewhere? So if the first part of that "code" is to explicitly indicate the vendor id and the product id, what does that 3rd part actually do? Seems kinda strange you would need to put some 5-digit code in a boot file to split a device into 2. Also.. what do you guys think? Does my "Sherlocking" sound right, that the 0x040 is the key? I'd like to get some feedback before I try it. But if not, I'll update tomorrow the results.

hansolo77

I definitely think the problem is with the 0x040 bit being 0x40. Everywhere I look, I find solutions from people using 0x040. In fact, here is a list I found on a "Recalbox" build:
https://github.com/recalbox/recalbox-buildroot/blob/master/board/recalbox/fsoverlay/etc/modprobe.d/usbhid.conf
They don't list the Raphnet device there, but I'm sure it would be there if that was still being updated. I tried to research the usbhid.quirks bit, and actually see a LOT of information. So I don't think I'll delve too much into it. Strangely, I didn't see any mentions though as to what 0x040 does, unless it's a special part of the device's chip programming that the designer of the circuit can utilize. That's getting too technical for me. I'll just be happy if this is my solution.

DIDN'T WORK
I was tossing in bed, this whole thing running around in my mind. I couldn't sleep, so I decided to do it now, and see if it fixes the problems. Long story short, it didn't work. The first thing I tried to do was to just change all the 0x40 bits into 0x040. Rebooted, and then did a ls /dev/input/by-id. Same results as before; only one joystick entry for the Raphnet. The next thing I did was to replace the original 0x40 but then erase all the other "devices" from the line. Rebooted, retested, same results. The last thing I tried was to replace the 0x040 to the line, but with the other "devices" removed. Reboot, Retest, Same Results. So at this point, I'm back in the "waiting to hear from Raphnet" mode. I could have sworn this was the solution I needed. Oh well. While sleeping tonight, I've decided to try and give the kernel another rebuild attempt, this time WITHOUT the Raphnet patches. I've had a couple of people mention now that the Raphnet fixes should be all included into the kernel. So maybe I'll get lucky, and the problem will be solved in the morning. For all I know, it could be a result of BOTH fixes. I need the latest kernel (without the patches because they're already included) AND a change to the /boot/cmdline.txt to have the 0x040 instead of 0x40. Here's hoping anyway.

Since I was tagged in this thread I'll comment a bit about my setup. I'm not sure that it will help.

I'm using genuine Nintendo controllers. Even the NES controller that I converted to use a SNES plug is a "real" controller from Nintendo.

I'm only using the two Super Famicom controller ports. I've not tried to use Bluetooth controllers, or any additional controllers. I thought about it, but since the Raphnet controller adapter shows up as four controllers I frankly didn't want to mess with the complexity of doing other controller options and instead got some cheap SNES extension cables and things work fine for me.

Every time there is a kernel update I do have to patch manually or I get the "northwest" problem, but I'm not sure if the issue has been fixed in Stretch. Since I'm still using the RetroPie images and updating through there I've not tried updating manually from Jessie as I understand that there are still somethings not supported in Stretch.

hansolo77

@obsidianspider Thanks for your comment. It's nice to know that I wasn't imagining it, and that the drift problem is still and issue. I'll get this all figured out eventually. :)

hansolo77

@mediamogul Do you know if I need the --detach-kernel-driver flag in my settings? I had a thought that maybe that's why the RunCommand stops working, because I've turned off the driver for the controller. I will test.

UPDATE
I've re-wired the USB plugs again, and have successfully managed to get the Raphnet to now always come up with the same event# regardless if my Xbox controller is on or off. All I had to do was connected it to port 0 (top left) of the Raspberry Pi. Now it always comes up as event0 and event1. Doing that caused my Xbox controller settings to get jacked up though. Because now RetroArch is looking for the Raphnet controller as the default Player 1 regardless of the emulator. I hope I fixed it though. I cleared out the retroarch.cfg settings again and re-created the controller mapping to the Xbox. I then set it so it would always use the Xbox controller as the default.

hansolo77

UPDATE 2
I have now configured a working XBOXDRV config to load via the runcommand-onstart.sh file. I've tested it with the Xbox controller both on and Off, and it works exactly like it should now. So YAY there. However, there is still an issue with RunCommand. I tried to # comment out the lines in the XBOXDRV config to see if I needed that --detach-kernel-driver flag. Apparently, I absolutely do need it. Without it, all I get is a black screen. The option to trigger RunCommand never displays, nor does the game. So I put them back into the config.

NEW ISSUE Back to RunCommand
Now that I've got the runcommand-onstart.sh configured and running like it should be, I'm back to the issue of not being able to trigger the RunCommand menu with anything other than the controller I programmed via XBOXDRV. Apparently, the RunCommand menu only excepts input from event0, js0, or a keyboard. By using XBOXDRV to remap the Raphnet controllers to a keyboard, I'm able to trigger RunCommand, and navigate, but I can't select any options. I feel like this a symptom of RunCommand limitations. In that it won't receive input from ALL controllers, and the only option to enter a menu is via the ENTER key. I would really appreciate it if somebody more in the know (dev's, etc) could look at this and consider updating it to allow condition. For instance, why does triggering require a specific controller (make it work with ALL controllers and ALL buttons). And then while navigating, allow input from all HATS, D-PADS, STICKS, etc. And then for selecting, allow input from "A" as well as "ENTER".

~~It probably doesn't matter in your case, but it's a good thought. I'd try it with and without to see it it makes a difference.~~

Progress, nice! What kind of controller are you using again?

Take a look at https://github.com/RetroPie/RetroPie-Setup/blob/3928a0570727f850ec8895cc18f77cad04d0d86d/scriptmodules/supplementary/runcommand/runcommand.sh#L106, on how the joy2key.py script is started by runcommand. I think you might want to fall on the else part of the test, which - from what I can tell from the joy2key sources - adds all input devices as possible sources.

Ah, that's insightful. Now if I only know how to cause the else statement. By using jsX, than means "ALL" right? I wonder if I can just add an extra mapping in the XBOXDRV to have it send ENTER and TAB along with what I have mapped to A and B. That would at least get me working INSIDE RunCommand. But I still don't have a way to trigger it with my Xbox controller if I don't have the NES controllers hooked up.

Well, for testing purposes you can copy the else branch code over the if branch. If that works, then you can see you get on that branch.

hansolo77

@mitu I don't really follow. Are you saying I should edit the script locally and change the programming to not include anything BUT what's in the else bit? IF that works, what's to keep it from going back in the future?

mitu

@hansolo77

for testing purposes

hansolo77

The problem with RunCommand is directly associated having the XBOXDRV becoming active via the onstart script. I was able to remap the A and B buttons on my NES controller to be ENTER and TAB, as per the notations in the runcommand.sh script. I'm not able to map the buttons simultaneously though. If I try to do both, it only takes whatever is last entry. So it's either A=A and B=B or A=START and B=TAB. So changing the maps in XBOXDRV isn't the solution.

I wonder if a script can be made to launch with the emulator, that would allow the Xbox controller to still remain as js0? The more I think about it though, that's probably just nonsense. It's so weird how it all works. RetroArch will use the Xbox controller as the default no matter what. But also uses the XBOXDRV overtop of that config because it's using a keyboard. I remember at one point trying to map the Xbox controller as a 3rd device, but that pretty much broke RetroArch. I'm probably just going to end up stuck with what I have unless the devs are willing to look at and update RunCommand to not require js0 if it exists.

hansolo77

So as a test, I changed the runcommand.sh script to # comment out the if/then statement and make it only load the jsX device. It now read as:

function start_joy2key() {
    [[ "$DISABLE_JOYSTICK" -eq 1 ]] && return
    # get the first joystick device (if not already set)
#    if [[ -c "$__joy2key_dev" ]]; then
#       JOY2KEY_DEV="$__joy2key_dev"
#    else
        JOY2KEY_DEV="/dev/input/jsX"
#    fi
    # if joy2key.py is installed run it with cursor keys for axis, and enter + tab for buttons 0 and 1
    if [[ -f "$ROOTDIR/supplementary/runcommand/joy2key.py" && -n "$JOY2KEY_DEV" ]] && ! pgrep -f joy2key.py >/dev/null; then

        # call joy2key.py: arguments are curses capability names or hex values starting with '0x'
        # see: http://pubs.opengroup.org/onlinepubs/7908799/xcurses/terminfo.html
        "$ROOTDIR/supplementary/runcommand/joy2key.py" "$JOY2KEY_DEV" kcub1 kcuf1 kcuu1 kcud1 0x0a 0x09 &
        JOY2KEY_PID=$!
    fi
}

This test didn't work. I still have the same results of not being able to trigger RunCommand.
