Raphnet NES2USB Struggles

obsidianspider

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.

@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. :)

@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.

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?

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.
