The core input remapping option doesn’t work for me either, so its likely an upstream issue that will need to be addressed. Taalas and I have been trying to sort out the whole configs things as well- you can see our progress here: https://github.com/taalas/RetroPie-Artwork/issues/2 it has diagrams that show the default retropad configurations (they are also on all of the retropie wiki pages)

As far as I understand it without the ability to modify the core inputs you have potentially two options that I can think of (both of which aren’t super effective)

– Autoconfigs: you can set up your autoconfigs for each controller to be mapped as you like for the genesis and then either swap out the files (which will be in /opt/retropie/configs/all/retroarch-joypads) or reconfigure them each time you switch emulators (which is also an inconvenience)

– Retroarch.cfg you can modify this file to be hardcoded specific to when you open the megadrive emulator /opt/retropie/configs/megadrive/retroarch.cfgand I’ve found out something in regards to player order (at least with autoconfigs, it may also apply to retroarch.cfg)- its based off of where you plug in your usb:

But there may also be a more effective way than what I can think of, if you’ve got any better ideas I’d be happy to hear them as I’m interested in finding a solution myself :)

They should all be set in your auto controller.

What do you get if you type this
grep -rnw '/opt/retropie/emulators/retroarch/configs/' -e "USB,2-axis 8-button gamepad"

That should show you where your auto controller is (as you have an iBuffalo)
Although you may get multiple results.

This is an older video, but it shows how the auto files work

Hi,
I’ve got the same issue with same controller.

I seen a post of someone said that this controller as issue with linux, and he has wired it on raspberry GPio instead

Another one (on Windows 7) said that it is an issue with USB 1.1 controler
He bought an old usb 1.1 controller to make it work on Windows.

I have tested with an ordinary hub, I was lucky that the 1st time I plug it was working but after same issue, I had to plug and unplug 10 times to make it work.
I guess with testing with some others hub more expensive (and more flexible with usb1.1) it can work better but I haven’t got any other hub to test with.

Let me know if you find somethig out
Thanks

[quote=100121]Ok are a few things here that makes the difference.
If you are on Windows I suggest you edit your file in your raspberry pi as you cannot see your file properly.
To edit your file under Rpi (linux) environment you can use this command:

sudo nano /etc/emulationstation/es_systems.cfg

Please note you must exit Retropie first in order to get your command prompt.

If you use linux in your desktop (Ubuntu ou other operating system) you can edit your file with other application like gedit but I’m affraid it’s not your case.

Because NANO has a very simple interface this link will help you in your find and replace journey:

http://artinpetrossian.com/?p=53

You will find lines as it follows

<path>~/Retropie/roms/EMULATORNAME</path> (something like this, I don’t have it in my mind right now as I’m outside my house)

And what you need to do is to replace this address to Your USB PEN Roms Directory.

Cheers!

ok thanks thats it sorted . and the info was spot on .

[quote=100120]Have you heard of Google? https://www.petrockblock.com/forums/topic/how-to-run-from-usb-the-best-method/#post-100012 indicates you wanted someone else to tell you everything (it was the first Google result if you had bothered).

re your latest “please tell me every single thing i should do” post..

/etc is a directory. Are you at a command line? have you tried “cd /etc” ?

Editors? There are many you can use.. you could try nano or vi…. but please find out how to use them yourself. There are many sites that can tell you the commands to load/save files and add/delete text.

I am not normally so unhelpful but you really do seem to be seeking a 100% spoon feeding without doing much yourself!!

I applied Feederchain’s 2nd updated custom kernel patch and it totally fixed all the problems I was having with my Xin-Mo (actually THT THT) usb 2 player set up.

I used it for about 2 weeks, then turned off my Retropie arcade for a week while I was on vacation. When I got home, the custom kernel had reverted to the original and the 2 player controls behaved like one giant player one controller again.

I reapplied the patched kernel and everything is fine again. Does this make any sense at all? Is there anyway that powering down the RasPi for a week could undo this kernel patch? Did I not use significant enough privileges when I applied it? Any help would be appreciated.

The easy way is to edit your es_systems.cfg file and changing the path line.

Here’s an example:

<path>/media/usb/Retropen/retropie/amstradcpc</path>

/Retropen/retropie/ are my USB pen drive folders

USB SNES Controller – D-Pad not working in games

So I did as Floob said and removed all config files in /opt/retropie/emulators/retroarch/configs/*.cfg

then ran
sudo /home/pi/RetroPie-Setup/retropie_setup.sh

and did the configuration for my controller.
Now it works as it should be :)

can anyone post the right way to run games from the usb ? and how is it set up ?

Create a folder called retropie on the usb drive first and it will place the ROM folder in there.

https://github.com/retropie/RetroPie-Setup/wiki/How-to-get-ROMs-on-the-SD-card

Since my opinion is like patrickm’s post I ask if anyone had issues running Retropie by SDCard and Roms by USB drive?
I have a 4GB SDcard (got it free) where I have Retropie image and all my roms are in a 64GB USB Drive.
So far I got no problems at all but somehow I figured out some time ago that if I have my USB Drive as ext4 and I don’t have saving problems (I got them when it was Fat32) nor loading problems.
Everything runs fast enough for me and the only thing I think it will improve running OS by USB is the Retropie startup because it takes some time to load all my roms for the first time.
In my opinion to run a “real” OS (like raspian or ubuntu mate) this guide will be the best choice but to run Retropie I don’t see any advantage since it takes less time using another sdcard and if something go wrong it can be a huge frustration to lose a lot of roms.
For the other hand I have another RPi for multiple purposes and I got a “generic” USB drive (64GB as well) with a folder in it with some roms and I can run them like a charm just by plugging it to my RPi. This is why I like USB Drive option most.
Correct me if I’m wrong.
Cheers!

my guess is all your buttons work but your dpad? it’s a controller issue that I had, this thread seems to have solved it: https://www.petrockblock.com/forums/topic/usb-snes-controller-d-pad-not-working-in-games/#post-97091
