Thanks for the tip. I'm aware of the 4-way restrictor possibility, but of course the drawback is that I'd have to take apart my cabinet each time I wanted to play an old 4-way game.... I need 8-way mode for most of the others. So I'm looking for a decent SW solution as opposed to a brute-force HW solution... hopefully one that's easier to implement than xboxdrv. Your work on lr-mame2003-plus seems like the closest thing for my purposes so far.

[grant2258]

you should try it at least once to see how a 4 way plays on you joystick its not that fantastic to begin with try kung fu master it 4 way does take a bit of getting used to when you are familiar with 8 way. I dont think any software solution will get it 100% analog position tracking can get closer but again no use in an arcade joystick or dpad where you just have a button on or off there is no way to track how far they are in between.

so if you go right then press right/up you will keep on going right )or last direction pressed until you commit to another direction.

This seems like a perfectly reasonable solution, but for whatever reason, the xboxdrv 4-way restriction doesn't seem to behave this way. With it, control is very precise on quick turns without any necessary forethought on how to to adapt to a new control behavior. The result feels very close to an actual restriction plate. All that said, I have no idea what is used in xboxdrv to accomplish this.

@PMac10000 Hi. I'm just wondering whether you followed @mediamogul's xboxdrv guide from scratch. My code will definitely help you, but may not be 100% for your purposes (eg your buttons might be wired up differently from mine and therefore be "named" differently from mine). From a troubleshooting point of view, where did it fall down for you? I might be able to help.

Your probably using it on an analog stick. try it on a none analog device analog is easier to track. digital only has 8 positions so this analog logic won't work on a sanwa or dpad tgat is what mame addresses

I am indeed and you're completely right. I don't remember if it's come up in conversation before, but MAME actually had it's own implementation of software 4-way restriction at one time. I believe the reason for its removal was that no one could agree on the best way to implement it effectively. While it might not be perfect, you're solution may very well be the best solution for most situations.

[grant2258]

@mediamogul the biggest problem is people using a square 8 way restriction plate that why i use circular one now less throw for shoot em ups as well. so you use the joystick rather than ride the restrictor. I would recommend a hexagonal you need help with finding you up/right ect. It is personal preference at the end of the day.

@spud11
Hard to say exactly where it went wrong, but I had modified so many scripts, cfg files, and parameters (xboxdrv, retroarch, mame) that I had to surrender and start over. I'll have a go again with a clean slate, and lean on your troubleshooting skills. Would it help to know how my particular buttons are wired as xboxdrv sees them? for example I can correlate THUMB2 with jstest value with X/Y/A/B, and so on...

Since your setup is so similar to mine, I'm wondering if you've had a chance to try out the built-in 4-way emulation in lrmame2003, and compare and contrast the gameplay experience with the xboxdrv approach. Thanks

@mediamogul Hi mediamogul. I've come across a problem I haven't been able to solve. I've manually compiled/installed the GSplus emulator (Apple IIGS) for my Jessie-based Rpi3B. GSPlus's internal joystick configuration doesn't work well, but most games have keyboard commands. I'm using xboxdrv to "tie" my DragonRise arcade joysticks to the keyboard. However, Gauntlet, for example, uses 8 keys for 8 directions (including diagonals). I'm not sure how to replicate that with xboxdrv. At present, I can only move left/right/up/down, not diagonally. I wonder whether you could help please.

Is there a way to get --ui-axismap X1=KEY_LEFT:KEY_RIGHT,Y1=KEY_UP:KEY_DOWN \ to reflect diagonal directions too?

Thanks.

@spud11

I'm pretty sure axis input can't be mapped in that way. To my understanding, you could really only map eight arbitrary keys to a DPad, making use of the --dpad-as-button argument and then combo mappings such as du+dl=KEY_W.

[spud11]

@mediamogul Thanks for that. That puts me on the right track. This zero delay arcade encoder has a "mode" button which apparently switches the joystick from analog to digital. I hadn't bothered to hook up a button to "mode" so far, so I'll investigate that and see whether I can get the joystick into digital mode and then have a crack with those xboxdrv settings you have suggested.

[mediamogul]

@spud11
One other thing worth mentioning is that you might want to map the two possible combinations for all four diagonals to avoid any dead input. So if you mapped du+dl=KEY_W, you would also map dl+du=KEY_W. That way, no matter which direction you happened to hit first in the combo, the intended action would still take place.

[spud11]

@mediamogul Thanks for that. That really helped. I attached a button to the "mode" port and, using xboxdrv, I can now switch between analog and digital on the fly with the code being:

@spud11

Very nice.

[spud11]

@mediamogul Hi. I was wondering please whether you could help. I've got what I thought would be a fairly simple problem, but can't find a solution. For my various MAME setups, I press the lt button on my arcade and it will effectively press the 5and 1 keys and start a single player game. If I press the rt button, it presses the 6 and 2 keys and starts a 2 player game. It's a nice and simple setup.

I'm trying to do the same with the libretro FBA cores using the back button, but for some reason, it will not work. Pressing the back button should insert Coin 1 (right shift) and start Player 1 (enter) automatically. However, I find that I have to press the back button twice to achieve this instead of only once.

I've also tried using a macro instead using

--ui-buttonmap back=macro:/opt/retropie/configs/all/fba_start_player1.macro \

and the macro:

send KEY_RIGHTSHIFT 1
wait 500
send KEY_ENTER 1

Strangely, the macro produces no result at all when I press the back button.

Would you have any idea please what might be the problem or other things I could try?

[mediamogul]

@spud11

I'm not sure if I've ever run into that exact specific issue myself, but I seem to remember that assigning a hotkey combo shared with the 'insert coin' function could get a bit squirrely with some of my various arcade setups in the past. I don't think I ever overcame the issue, as none of my current setups include 'insert coin' in a key combo.

One other possibility I was thinking...

I'm almost certain xboxdrv can't bind keyboard keys with other keys/key combinations, but if you could find an outside solution to handle that part, it should work well.

I thought I'd let you know that I finally figured out how to exit Moonlight at both ends using xboxdrv - server and client side. (It may be that Moonlight has been updated since I last posted on this so this is now a non-issue, but my version of Moonlight and Retropie are quite old).

I've got a macro set up in my xboxdrv configuration:

--ui-buttonmap back+rt=macro:/home/pi/RetroPie/roms/steam/MS_exit.macro \

The macro has the following content:

wait 100
send KEY_ESC 1
wait 100
send KEY_ESC 0


send KEY_LEFTSHIFT 1
send KEY_LEFTALT 1
send KEY_LEFTCTRL 1
send KEY_Q 1
wait 100
send KEY_LEFTSHIFT 0
send KEY_LEFTALT 0
send KEY_LEFTCTRL 0
send KEY_Q 0

This first sends the ESC key and then sends Shift+CTRL+ALT+Q to fully exit Moonlight, on both client and server sides, effectively using one button press instead of the 2 we were using when using the "cycling" technique.

[spud11]

@mediamogul I've also solved my problem with the libretro FBA cores by using a similar technique. I can press 1 button and it will both insert a coin and start the game without having to press a second time. The macro looks like this:

wait 100
send KEY_RIGHTSHIFT 1
wait 100
send KEY_RIGHTSHIFT 0
wait 100
send KEY_ENTER 1
wait 100
send KEY_ENTER 0

I have an arcade cabinet with 2 zero-delay encoders, containing a total of 16 buttons and 2 joysticks, and I am trying to use dosbox without needing a keyboard nor a mouse. With the default dosbox-mapper, multiple buttons have been set up as standard keyboard buttons and there is a dedicated exit button. Also 1 joystick functions as the arrow keys. By using xboxdrv I am trying to let the second joystick function as a mouse and to let 2 buttons function as mouse presses. I did evtest to write down all the button events. I made a file in /opt/retropie/configs/all/ called runcommand-onstart.sh and started with

if [ "$1" = "dosbox" ]
then
sudo killall >> /dev/shm/runcommand.log 2>&1 xboxdrv
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv >> /dev/shm/runcommand.log 2>&1 \
   --evdev /dev/input/event[1] \

However I am stuck after this part. Can anyone help me with setting up the mapping file further? If possible only mouse-movement and a left- and rightclick must be added, as the rest of the buttons is already mapped with the default dosbox mapper. Thank you in advance!

if you add this to what you have posted (of course change to match your system)

and make sure you have a runcommand-onend.sh as the guide says. you should be good
