Ah, I almost forgot to give an example of how you would handle this ROM-specifically from the runcommand-onstart. There are quite a few ways actually, but this is probably the easiest to illustrate and it uses the xboxdrv launch command I posted above. You'll notice I only used three games, but you can add as many as you want accordingly.

ROMNAME="${3##*/}"
if [ "$ROMNAME" = "pacman.zip" ] || [ "$ROMNAME" = "mspacman.zip" ] || [ "$ROMNAME" = "jrpacman.zip" ] && [ "$2" = "advmame" ]; then
  sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
    --evdev /dev/input/by-path/platform-3f980000.usb-usb-0:1.2.1:1.0-event-joystick \
    --detach-kernel-driver \
    --force-feedback \
    --trigger-as-button \
    --deadzone-trigger 15% \
    --deadzone 4000 \
    --device-name "Logitech Rumblepad 2 (xboxdrv)" \
    --silent \

@mediamogul - Thank you for the help and information. I am going to give it a shot and will let you know how it turns out. I have a few more questions but you've given me plenty here to get started, thank you good sir and have a great weekend.

On a side note, are from the Carolina's? I have no idea why I keep thinking you are from that area and I was thinking of you during the weekend of that devastating hurricane. If I remember you were doing yard work in like April with some nice weather and we got hammered here for one of the biggest snows on record that month. I almost posted a pic for you to check it out. ;)

[Riverstorm]

@mediamogul - Just to clarify one thing below. I've been following your guide and in the example you'll see tl and tr in the keymap line shown below from the guide examples but on the controller mapping diagram it shows as lt and rt is that a typo in the line?

--evdev-absmap ABS_[X]=x1,ABS_[Y]=y1,ABS_[RX]=x2,ABS_[RY]=y2,ABS_[•]=lt,ABS_[•]=rt,ABS_[HAT0Y]=dpad_x,ABS_[HAT0X]=dpad_y \
--evdev-keymap BTN_[SOUTH]=a,BTN_[EAST]=b,BTN_[NORTH]=x,BTN_[WEST]=y,BTN_[TL]=lb,BTN_[TR]=rb,BTN_[TL2]=tl,BTN_[TR2]=tr,BTN_[MODE]=guide,BTN_[SELECT]=back,BTN_[START]=start \

Also since my triggers register as buttons do I just delete these two entries from absmap line and only use the keymap entries ?

ABS_[•]=lt,ABS_[•]=rt

I am indeed sir. Born and bred in the briar patch of beautiful South Carolina. We got really lucky in my area. Of course, I'll still be spending most of the weekend and probably next on cleanup. However, no trees came down, which is always a good thing.

Hey, never hesitate. I love seeing that stuff. Nature, with all of its crazy ups and downs, is the main reason I enjoy living here so much.

Actually, they're a separate entry. The 'tl/tr' listings are the xboxdrv equivalent to what's more commonly referred to as 'l3/r3', which are the buttons activated by pressing down the two thumbsticks.

Also since my triggers register as buttons do I just delete these two entries from absmap line and only use the keymap entries ?

I believe you would, yes.

In the briar patch eh, love it! ;) That's great to hear! Mother nature can be a nasty girl for sure. I'll be spending about half my weekend outdoors too just "winterizing". It's getting pretty cold at night. I think the 30s this evening (frost advisories) and 50s during the days.

I replaced the soffit and fascia on the shed that needs painting, replace an outdoor water faucet, seal my garage floor (the chemicals on the streets they use to melt snow eats concrete pretty good), drain hoses, pack-up summer deck chairs, tables, umbrella, bikes, etc.

You can delete this pic as not to to go off topic with pics of snow and controllers but here's a pic of what's happening on the west side of the state, here, today. Way to early for this stuff but the good is we won't see it here on the east side of the state, today at least but it's coming soon. ;)

I'll get you a pic of that storm this past spring. It was pretty neat to see it that deep so late in the season, my youngest daughter had a ball in it!

Wow, that was yesterday? With enough distance you can't help but see it as a work of art, but I'm sure you guys feel a fair amount dread along with it. Exactly where do you hail from again?

[Riverstorm]

@mediamogul said in Guide: Advanced Controller Mappings:

Yeah that was this past weekend even though it's a bit early for snow. To be honest I actually love the snow and cold. It's the cold and wind combined that I don't care for so much.

I am in South Dakota. So we here can appreciate that north/south distinction like you but some just don't care and lump as one in their mind. ;)

The Missouri river divides the state almost down the middle and that's where the time zone changes from Mountain to Central. People in Mountain time are referred to as West River and those in Central are East River. West has the scenic Black Hills, Badlands, Mt. Rushmore, Sylvan Lake (it was in the movie National Treasure but it's not behind Mt. Rushmore). The area is surprisingly great for really decompressing and taking all that scenic nature in if you can break yourself away from the tech you remember how nice it can really be outdoors. The East is much flatter more about agriculture and livestock. It's more metropolitan but still good hunting, camping, fishing, etc.

I love camping and fishing but not so much hunting but we will drive out in the country to shoot guns at whatever. Hunting is huge here and brings in a lot of tourists in the fall. Our population density is real low so if you like wide open spaces or a quiet acreage you got it within 10 minutes in any direction. We did make the top 5 places to live this year but the one demographic that is highly held as negative is the weather, people just don't like snow and cold. They just need to get in touch with their inner child and build a snowman again! ;)

[Riverstorm]

@mediamogul - An actual post related question. ;) Yeah I was confused when I saw rt/tr. I thought it was a typo as they are just inverse but both are different mappings. I see now what you were saying.

Also you're correct it does list all 4 joysticks in by-id. I use two different Microsoft wireless dongles and the 'by-id' name seems to change based on which Microsoft wireless dongle is in use. The E0C number part of the name listed below is what's changing but the rest of the name is consistent. Is this possible to include?

usb-©Microsoft_Xbox_360_Wireless_Receiver_for_Windows_E0C26450-event-joystick

usb-©Microsoft_Xbox_360_Wireless_Receiver_for_Windows_E0CA52D0-if06-event-joystick

The other thing is the D-Pad. I see it's has both an ABS and BTN value such as BTN_TRIGGER_HAPPY1 and ABS_HAT0X should I add them both, one each to the absmap and keymap lines? Does it distinguish between the two somehow?

[mediamogul]

@riverstorm said in Guide: Advanced Controller Mappings:

Sylvan Lake (it was in the movie National Treasure but it's not behind Mt. Rushmore)

Ha! I like those movies well enough myself, but I've talked with so many history and geography buffs that go off on them for those inaccuracies. It's a bit understandable too. I mean, each outing they spend half the movie trying to wow the audience with little known facts about America and then proceed to misrepresent just as many for the sake of convenience. Nonetheless, SD sounds like my kind of country for sure. Rumor has it, you guys are hiding a West Dakota from the tourists and keeping it's ultimate splendor to yourselves. If I ever happen to make it out that way maybe you could get me past the bouncer.

The E0C number part of the name listed below is what's changing but the rest of the name is consistent. Is this possible to include?

If you use the by-id location for the --evdev argument, it'll assure that the controllers are delineated properly.

The other thing is the D-Pad. I see it's has both an ABS and BTN value such as BTN_TRIGGER_HAPPY1 and ABS_HAT0X

Each controller should either have one or the other. You said that you have two controller types, so is it that the DPad differs between the two? Keep in mind that the controllers are not mapped all together. Each instance of xboxdrv maps a separate controller, so if it is that the inputs differ between types, they can be mapped accordingly in their own instance.

To true! I think that's how rumors get started by mixing fiction/non-fiction. "Duh, haven't you seen National Treasure? Everyone knows there's a lake behind Mt. Rushmore!"

The wife cleared me so if you're ever in this area ping me in a post and we'll take you out for dinner. Her only condition was she wants to tag along on the trip to West Dakota, it'll be her first trip there too! :) After West Dakota I am thinking East Dakota could be fun too!

Ok well to be honest here I am swimming in information and kind of getting lost. The first part of the guide I followed like a champ and have all the information documented in a file but I am lost on putting it altogether. It's a bit overwhelming to understand what all needs to be done.

Breaking it down the first step is to get the right number of instances loaded in the rc.local, second create the runcommand-start and also I think I'll need a runcommand-exit?

Just to verify if I wanted to cover both wireless dongles I would need to load 8 instances in the rc.local file since each dongle shows a different by-id for the 4 controllers?

Also would I add all 8 controllers to the code runcommand-start? In the example below it loads one? Would I need to repeat the --evdev command and controller parameter lines below 8 times between the if/fi? Or would I need to get into something like section 3B - Expanding Launch Capabilities? I am not sure if that makes sense.

Lastly is there a list someplace already to match all 4-way games in mame2003?

ROMNAME="${3##*/}"
if [ "$ROMNAME" = "pacman.zip" ] || [ "$ROMNAME" = "mspacman.zip" ] || [ "$ROMNAME" = "jrpacman.zip" ] && [ "$2" = "advmame" ]; then

fi &

I did shut off all controllers except one for testing and it does look like the XBOX 360 d-pad has both a BTN_ and ABS_ value. Both models output the same exact values for all buttons and axis'. In the output below I pressed left and then right once. You'll see the values defined on the top portion when the command loads and also the properties right below it when pressing the d-pad. It seems to output two values for each press.

If you just want to 4-way restrict in certain software, with certain ROMs, you can ignore doing anything to rc.local. For example, I use my plain vanilla controller to play most games, but I use the onstart/onend scripts to launch mappings only for the games I wish.

if I wanted to cover both wireless dongles I would need to load 8 instances in the rc.local file since each dongle shows a different by-id for the 4 controllers?

I'm a little uncertain as to why your controllers are producing two events each. Are you using a driver such as xpad? It could be that there's the original event and then another created by xpad. That's actually how xboxdrv does things, so it would make sense.

Also would I add all 8 controllers to the code runcommand-start? In the example below it loads one? Would I need to repeat the --evdev command and controller parameter lines below 8 times between the if/fi? Or would I need to get into something like section 3B - Expanding Launch Capabilities? I am not sure if that makes sense.

You can use either. I just use if/fi. There, the basic logic is that if the criteria is met, then commands are performed. In this case, one instance of xboxdrv is a command. For four controllers, you would say that if the criteria is met, four xboxdrv commands are performed. Those commands begin with sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv and end with the final -- argument, at which point you would either list another xboxdrv command below it, or end the if/fi with fi &.

Lastly is there a list someplace already to match all 4-way games in mame2003?

The list I posted above is as close as you're likely to find. From what I remember when looking myself, the available lists tend to only note parent ROMs. Mine is based off those findings, but I've added the clones that I find important, like pacman.zip for example.

[Riverstorm]

@mediamogul - Let me do some more "studying" here. Ok I wasn't sure if that was a comprehensive list or most of the 4 way games in mame2003 only or all emulators supported in RetroPie or just what you've come across? I sorted them alphabetically below if you have any use for it.

My goal is pretty simply and that's to improve 4-way games for a better play experience on the vanilla XBOX 360 controller. Sometimes I have 1 plugged in, maybe 2 and occasionally all 4. Rarely 3 for maybe say Xenophobe.

How simple may I go?

1. Load the driver
2. Configure my controller through ES
3. Create the runcommand-start checking ROMNAME but add only --four-way-restrictor

Would this work in the Arcade folder with no emulator specified in the 'if' statement?

I don't need to do any type of cleanup on game exit?

It might be a bad habit but I spend all my time in planning before doing anything and usually (hopefully) very little in actual implementation.

I see the value in having complete and granular autonomy on each mapping for precision configuration. Plus I love the ScummVM example but just getting something simple in place to start would be great and maybe someday it will be a standard. I almost feel 4-way restriction on the correct games is a must long term, especially if the implementation is easy and straight forward.

I know the day I started this and I posted a question at you because I had this guide up for weeks in a TAB waiting to get around to it. I saw Robert created a new issue with Plus and I thought perfect timing! I wasn't sure if it was coincidence or he was watching the forums and the post prompted some idea or motivation.

Anyway I think @grant2258 has nailed something good in Mame2003-Plus. With a few lines of code he added 2 new options in the RA settings (Quick Menu/Options/last option in the list) for 4-way games 'XOR' and 'Last Pressed' that seem to be working pretty well. I think they plan to make it standard for a good 4-way game experience out of the box but want to do more testing with it first. If you or anyone have it loaded you probably have a good feel for certain games you play often or any feedback for improvement can be posted here.

@mediamogul - Thanks for all the help and advice working on this, I really appreciate it. I'll let you know how things go.

@riverstorm said in Guide: Advanced Controller Mappings:

Sorry, I somehow missed your last reply

Load the driver
Configure my controller through ES
Create the runcommand-start checking ROMNAME but add only --four-way-restrictor

All that is correct. You'll still need to make a basic map from your controller to the virtual xboxdrv controller, but the only fancy thing you'd add is the 4-way restriction.

Would this work in the Arcade folder with no emulator specified in the 'if' statement?

If you specify that the xboxdrv command be launched with the arcade system criteria it would. For example:

if [ "$ROMNAME" = "pacman.zip" ] && [ "$1" = "arcade" ]; then

An example of using the emulator as the criteria would look like:

if [ "$ROMNAME" = "pacman.zip" ] && [ "$2" = "advmame" ]; then

I don't need to do any type of cleanup on game exit?

Yes, it's actually covered in the guide at some point that you'd need to add something to the tune of:

Plus I love the ScummVM example but just getting something simple in place to start would be great and maybe someday it will be a standard.

Originally, I used ScummVM as the main example because of the stuttery joystick support it had not too long ago. However, it's native support is very smooth now. Still, it's nice to add other things like matching the same button combinations to quit that you use in RetroArch for example. I run 32 different systems and many different ports and it really is great to have the same button combinations for all of them to quit, pause, take a screenshot and bring up the options menu.

Anyway I think @grant2258 has nailed something good in Mame2003-Plus.

I've been following that. It's a great addition. I've been meaning to test it, but I just can't seem to fit enough hours in the day lately.

Thanks for all the help and advice working on this, I really appreciate it.

It's never a probelm. If you decide to put any of this to practice, I think you'll find that it can come together fairly well once you start going through the steps. Something like this in theory leads to an endless amount of what ifs.

@mediamogul - You're great, your documentation and advice are the only thing that's making it possible for me to add this amazing feature and I appreciate the help tremendously. I just figured you were busy and it's a good spot for me to pause for a moment too.

I know what you mean about not enough hours in the day. I took a vacation day yesterday to go home and work. How's that for the American dream. ;) I hope to continue working on things this weekend. I also need to replace two electrical outlets and two light switches as the wife is hard on that stuff. I don't what she does but it looks like she has WWE Smackdown's with this stuff or something when I am gone.

Here in the fall stores like Lowes, Home Depot and Menards are packed as everyone is scrambling with fall projects before winter. Once winter hits it's way to cold for paint, caulk, water, anything will freeze, crack, peel, etc. as it's well below freezing most days and things can't set and seal. Last night we hit 34F...burrr...I had to pull the plants into the garage due to frost advisories. I will still work outside in a light jacket in November doing little things but all big projects are off the table until next spring that late in the season. I am just a cold weather person vs. heat.

If you do get a chance to test the changes Grant made to the code for 4-way games I would love to hear your thoughts on how it feels vs. managing it through the xboxdrv driver. It's pretty straight forward as the ROM sets are mostly the same and you can dump them in either arcade or mame-libretro (whichever one you don't use or both) for a quick test. No configuration just a quick setting change under Quick Menu/Options near the bottom. I've tested some of the classics and it feels pretty good to me.

Even if it's perfect there's still going to be a big need for the xboxdrv way because it's only one core vs. a whole lot. You run 32, I think I am around 10 cores, mainly MAME, Nintendo and Atari. How many cores total does RetroPie support. I see the list in the docs but never counted all of them.

You're right, I just need to get in there and some of these questions will be answered as I work through it. I will let you know how things go once I get few straight hours of leisure time to sit down and dig in as 5 minutes here and there is probably not going to cut it the first time through.

I think it's a work habit. I pre-configure switches, routers, firewalls, etc. and then I create very short maintenance windows to flip over to the new equipment. It also doesn't hurt to pull a Scotty. "I need 30 minutes, captain!" and pull it off in 15 but my boss is incredibly technical for being a director so that doesn't always work. We are replacing about 1/3 of our switches this year and that includes some critical functions like Metro Communications (911). I'll let you know which day to not have an emergency! ;)

Oh man! I know that movie. I had a plumber come in to install a second water heater not too long ago and the guy made a real mess of things. When the fit hit the shan I had to take a day off to fix the situation myself. The whole point of calling someone in the first place was to keep it off my plate. As Charlie Brown said so eloquently time and time again; ugh!

Certainly. At the moment, it's only available in lr-mame2003-plus right? As long as there aren't any dropouts between the restricted directions I'm sure it'll do the job well.

How else does one maintain a reputation as a miracle worker? ;)

Yeah it's only in Plus currently. I don't think it's to many lines of code and maybe it'd be possible to port it to the other cores. After testing it's been whittled down to one option, "Last Pressed".

The basic theory is the character will travel in the same direction until a new direction is established ignoring diagonals. So if you're traveling right you will continue right until say you press up.

Basically like a 4-way acrade joystick is how he coded it. You travel in one direction until a new direction is set.

When I look at my restrictor plate on a real arcade joystick it's a diamond shape so it will naturally "lock" direction into one of the 4 diamond tips. A controller has a bit of play since the "restrictor plate" is a circle so I think there's still room for error compared to a true arcade stick.

It feels real good but I would be curious how it compares to the xboxdrv driver restriction. Regardless I think his code could be a benefit to all the Libretro MAME cores, it requires no configuration and works out of box for a better experience. That's just a win-win.

I hear you on "contractors". I don't mean to sound cynical but I trust very few. My Dad when he was alive was through and through a DIY guy so I came by it honest but there's still a few things I am not comfortable with.

I'll change electrical outlets, switches, 3-way, 4-way, install new outlets and run them back to the fuse box, etc. but I am just not comfortable working inside the actual fuse box. Everything else I'll give it shot and I am pretty comfortable but like you there's some things I'll just pay for to be done with it sometimes.

The last big mess I had from a contractor was a radon system that started falling apart a few years after installation. He didn't use primer with the glue on PVC. I called him and we had a nice discussion on the merits of a $3 can of primer. It took a weekend but I had to build a new run from my basement, through the basement wall, up the garage wall (for legal reasons it can't be in the house), through the garage attic and out through the roof.

Just for fun a few weeks back I ran some LED strip lighting under the length of kitchen cabinets. It turned out really nice and looks great especially in the evenings set on low. I think it'll be fun for social gatherings.

Anyway I am pretty grateful and happy as I believe maintenance costs in a home are still cheaper than letting it completely fall apart and then replace it and it's not the "The Money Pit". I throw out those movie/TV references because none of them are lost on you. ;)

I'm hoping to try it out this evening alongside 'Donkey Kong' for this weeks MAME ROW. Without good 4-way restriction, Mario just loses interest half way up the ladders, when you can get him to climb at all.

Ha! Well done sir. That has to hold the record for the most obscure 80s comedy reference on this site. I used to rent that quite a bit back in the day. I always felt like it was half-way educating me to future home life. Along with 'The Volunteers', I personally believe it's Tom Hanks' most underrated comedic movie. I'd even go so far as to say it's Shelly Long's best, although 'Don't Tell Her it's Me' is so bad it almost doubles around to being good again.

@mediamogul - lol...and there short ladders too! If you ever write a book I imagine it would be a real hoot to read. Mario making it to the top of the ladder with The Money Pit playing in the background. Sounds like a pretty good evening for me. The club scene has pretty much all but played out for me long ago. Now I am just waiting for my nieces and nephews to be "initiated" into the 21 club and my work is done. Oh the horror stories of those early drinking days at a club. ;) My oldest was there a long time ago and my youngest has a ways to go.
