Sorry @Rascas the name of my USB Controller is "USB gamepad " (with 8 spaces)

SOLVED

Making RetroPie identify 2 players instead of one with the Xin-Mo, THT Arcade console 2P USB Player

Add the following to /boot/cmdline.txt (just add a space to the existing entry so its all on one line)
usbhid.quirks=0x16c0:0x05e1:0x040

The first two numbers the vendor/product (16c0 and 05e1).
You can find your vendor/product using lsusb

@jkristof MAME is the trickiest of all the emulators.

I'm not sure where you are finding your rom files, but there's not a single site that I can think of, where after the download, you would need to make it a zip file.

That's probably your first problem.

Second, if you are able to select a game, hold the A button to go into the menu options and change the emulator until the games works for you.

There's a few to choose from and many games only work on one specific emulator.

Also, using WinSCP is probably the easiest way to transfer files if you're using a Windows based computer.

When using WinSCP, the default Username is: Raspberry
Password: Pi

To find your Raspberry's I.P. address, you can do that in the menu system when running Retropie.

@drake999

That it is my friend.

@Concat update

ok so I'm starting to figure out a little bit of all this. I went back and changed it to "OFF" for "sort saves/savestates in folders" and now its saving and loading ROM data inside of that "_ROM saves" folder I made, without making multiple directories. Its just clumping all of NES/SNES together in that one folder, which I guess I am OK with.
Look like I have that problem taken care of.

Hi,

I tried to follow the instructions on the following page:
https://www.raspberrypi.org/documentation/linux/kernel/building.md

The new kernel 4..4.13:

pi@retropie:~ $ uname -r
4.4.13-v7+

Works better and my Logitech Rumblepad started working as expected:

pi@retropie:~ $ dmesg | grep logi
[ 4.454487] logitech 0003:046D:C20A.0001: input,hidraw4: USB HID v1.10 Joystick [Logitech WingMan RumblePad] on usb-3f980000.usb-1.2/input0
[ 4.454617] logitech 0003:046D:C20A.0001: Force feedback for Logitech variant 2 rumble devices by Anssi Hannula anssi.hannula@gmail.com
pi@retropie:~ $ lsmod | grep logi
hid_logitech 20896 0
ff_memless 4750 1 hid_logitech

The module dependencies are now like those on my Intel notebook using Ubuntu.

@kris964 I just got all of mine from the same place and have a full Neo Geo romset. Heaven.

UPDATE: It's not that I don't know which file is the source of the problem, I just don't know how to check. If somebody would tell me how, that would be great. Also, this same problem was present on a Raspberry Pi 3-something, and this is the second time the file has been put on the SD Card. I don't know if that will help fix my problem.

got it (with patched update-rpi.sh) working:

pi@retropie:~ $ curl 'http://pastebin.com/raw/e2ZKSMr1' -o 'patched_rpi-update.sh' -L -B
pi@retropie:~ $ tr -d '\015' < patched_rpi-update.sh > ./patched_rpi-update
pi@retropie:~ $ sudo chmod +x ./patched_rpi-update
pi@retropie:~ $ sudo ./patched_rpi-update 771a503cfc2a1130e2df2a4ddfc45ffa0f592b3f

Looks like adv-mame 1.4 has rudimentary rotary control support. It's playable but not perfect. The Analogue Controls section needs tuning.

Around 10-12 Digital speed and about 100% Sensitivity.
Dunno what auto centre does.

My Trackball was having issues with mouse polling. When I spun it too fast it would register the spin in the opposite way. I had to add "usbhid.mousepoll=1" to "/boot/cmdline.txt". To increase the poll rate.
Most people recommend mousepoll=2 but I was still getting backspin. As yet I haven't noticed a performance reduction at mousepoll=1. The back spin seems to be all gone.
I also had to plug the Trackball directly into the RetroPie USB. It was in a little USB hub but the USB hub speed wasn't enough

@steven I have a Wise USB adaptor which handles Saturn, Dreamcast and N64 - it works perfectly with my original N64 controllers. I've not yet been able to activate rumble on the N64 controller (I don't use the libretro mupn64plus emulator as it's too slow).

That said I can't enable rumble on the Playstation Dualshock either (using any emulator).

There's a list of the hardware I'm using, with links to Amazon, RS Components etc, for most of it here

i think it must still be an issue.. so yeah, go ahead :)

@meleu said in Questions about RetroPie with Multiple Remotes & the Retrode:

I think player 2 can invoke RGUI (usually select+X) and choose "Quit RetroArch".

Ah I didn't know that. Thanks :)

It's in the wiki. Check here.

@JCrew7384

I was asking for exactly the same thing. After some research a while back, I found out that I can do that in Pi!

Prerequisites:

An additional SD card installed with Raspbian. I will refer this card as technical card because this is the card that I keep to do dirty jobs, experiments etc.

A USB card reader, preferable one that can allow you to access 2 cards at the same time, so that you can do the cloning directly. i.e. https://www.amazon.com/Kingston-Digital-MobileLite-Multi-Function-FCR-MLG4/dp/B00KX4TORI

Instructions:

Backup the card that you're going to edit. Important if you do this for the 1st time. I'm very new to Raspbian or Linux, so I took that precaution - safety first :)

Boot your Pi with the technical card. Install "GParted".

sudo apt-get install gparted

It's a GUI based partition editing tool. You can shrink/move a disk partition with this power tool.

Attach the card reader with the card you're going to edit into one of the Pi's USB port.

Fire up GParted.

Make sure you select the correct card in the upper right dropdown list. In my case it's "sdc".

https://www.dropbox.com/s/pnphammkkiase31/2016-06-17-004736_1039x507_scrot.png

Unmount the partition that you're going to edit (in my case /dev/sdc2). You can do this right in the GUI. Highlight the partition and right click, choose "Unmount". Note that after this operation, the key right after the partition name will disappear.

After that partition goes offline, you can edit it by choosing "Resize/Move" from the same right click menu. Adjust the size to your liking.

https://www.dropbox.com/s/9xye6da7eva80sc/2016-06-17-005026_552x298_scrot.png

Apply the change: Edit->Apply All Operations and wait for the writing to finish.

https://www.dropbox.com/s/vjap5k5gxqntzww/2016-06-17-005125_1039x507_scrot.png

That's it.

EDIT:

I forget the last final step.

I am using this card reader:
https://www.amazon.com/Kingston-Digital-MobileLite-Multi-Function-FCR-MLG4/dp/B00KX4TORI

It can access 2 SD cards at the same time.

So I can clone sd card to sd card directly:

sudo dd bs=4M count=1280 if=/dev/sdc of=/dev/sdd

sdc is the larger card, sdd is the smaller card (8GB).

Total cloning size is about 5GB (4M x 1280).

this was the missing piece

#Pretends all audio formats are supported by display, allowing passthrough of DTS/AC even when not reported as supported.

thanks lots floob!!

@alfredox123 that's good to know
