Hi guys – pretty new to RetroArch/Pie. Struggling with a few things and this is one of them! Latest version of RetroPie from the site.

My /opt/retropie/configs/all/retroarch-joypads/

input_device = "raphnet.net (S)NES/Atari_USB"
input_driver = "udev"
input_l2_btn = "6"
input_start_btn = "3"
input_exit_emulator_btn = "3"
input_up_axis = "-1"
input_a_btn = "4"
input_b_btn = "0"
input_reset_btn = "0"
input_down_axis = "+1"
input_r2_btn = "7"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_x_btn = "5"
input_menu_toggle_btn = "5"
input_select_btn = "2"
input_enable_hotkey_btn = "2"
input_y_btn = "1"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

# ======================================================================
# Config : raphnet.net (S)NES/Atari_USB : Hotkeys
# [Select] + [Start]      : Leave the game
# [Select] + [R]          : Save state
# [Select] + [L]          : Load state
# [Select] +           : Reset
# [Select] + [DPad-DOWN]  : Previous shader
# [Select] + [DPad-UP] : Next shader
# [Select] + [DPad-LEFT]  : Decrease state slot
# [Select] + [DPad-RIGHT]    : Increase state slot
# ======================================================================

input_save_state_btn = "7"
input_load_state_btn = "6"
input_reset_btn = "1"
input_shader_prev_axis = "-1"
input_shader_next_axis = "+1"

I have applied a single shader and it works…. but i cannot get the shader switching to work.

Also the STATE Hotkeys work – but not the Shaders

Any ideas?

PS I have updated the binary as well.

yes when i do the mapping and it ask type on the 360 crontroller nothing happens.
so it is like when i am in the green part the xbox controller can not be recognized the clicks.

In the main menu where i choose gameboy, snes etc it works fine.

in the green menu my other usb cable controller works fine

I installed mine directly with a USB keyboard rather than over ssh, I don’t know if that makes a difference. Really it’s more a novelty than a practicality and I’d definitely recommend hardware over it if you have it.

Very nice! I’m planning to build something similar. I noticed in another post of yours referencing this one that you use XBox controllers in combination with the arcade sticks. I posted a question in another thread about something similar. I would like to be able to use the sticks with nothing else plugged in, but then also be able to plug in retro USB gamepads. How does the controller hierarchy work with this? I would like the sticks to be player 1/2 unless I plug something else in, then that becomes player 1 or 2. Will this work with the iPac2 interface? I’m trying to figure out what parts to buy to interface my joysticks/buttons with the Pi.

How did you format the usb storage device? Is it a flash drive? or HDD?

Actually, let me back up. You say all of the roms were copied from usb to the rom folder on the sd card? Have you restarted the pi, and the the emulators still don’t show up?

[quote=115345]this isn’t libretro/retroarch issue. pcsx-rearmed (the playstation emulator) does not support 3/4 player controllers: https://github.com/notaz/pcsx_rearmed/issues/43

your controllers should work fine in libretro mame cores. consoles like the snes need a special configuration to support 3/4 players (it’s in the wiki/forums)[/quote]

Ahhh, okay that makes sense. I spent so much time trying to configure it to get it to work, and it wasn’t even possible, haha. Thank you very much for spending the time to reply and let me know.

@gamesfan

When you try to run:
sudo apt-get install --no-install-recommends joystick checkinstall bluez-utils bluez-compat bluez-hcidump libusb-dev libbluetooth-dev

Does it give you an error with bluez-utils? (Removing it from the command will cause it to tell you bluez-compat doesn’t work either)
Try this instead, and then follow the guide like normal:

sudo apt-get install --no-install-recommends joystick checkinstall bluez bluez-hcidump libusb-dev libbluetooth-dev

3.4 has been out a wee while now.

Changes since 3.3

Now using Raspbian Jessie for the RetroPie image.

Fixes for controller input issues with RetroArch including improved config generation to work around problems with 8bitdo controllers.

Fixed up Bluetooth pairing module on Jessie.

Improvements to the Xbox userspace driver (xboxdrv) including partial support of Xbox One controller.

Can now choose to exit or restart Emulation Station. Metadata will no longer be lost if choosing to shutdown or reboot.

Preliminary support for using the RetroPie-Setup script on x86 + X11 on Debian/Ubuntu and Ubuntu on the Odroid-C1 (building from source only).

$HOME/.emulationstation has relocated to /opt/retropie/configs/all/emulationstation – but is symlinked from the original location. The USB Rom Service script will backup all of /opt/retropie/configs to USB. Previously it only backed up /$HOME/.emulationstation.

Support for choosing RetroArch shaders and overlays from the RetroPie-Setup configuration editor.

Added pixel theme from Rookervik to theme installer.

Wonderswan and NeoGeo Pocket separated into Wonderswan/Wonderswan Colour, NeoGeo Pocket/NeoGeo Pocket Colour.

Various other bugfixes and improvements.

the es_system.cfg change is one way of doing it, and the symlink way is another. you appear to have done both and that will just make both not work :)

the symlink instructions posted by @smartroad are exactly how i did it and a perfect tutorial for that method IMO. you can’t get it any simpler because it needs all those steps. it’s not particularly easy because you’re trying to get around the fact that linux assumes USB is temporary storage, and make it treat it like a static drive.

the es_system way is just to edit the es_system.cfg to point to the relevent directories on the USB drive. there’s videos on this:

note you also need to turn off the USB rom service in the retropie setup menu, for both methods.

Just agreeing with the umount bit. As a safety measure, a button to trigger a shutdown or reboot command is an absolute must with your roms on a usb drive.

I mounted my USB stick as ~/RetroPie/roms/

I formatted the disk to ext4 as it provided a good read/write speed compared to FAT (and I don’t plan on removing the drive anyway as I backup ROMs over the network).

Then I found the drives unique ID (UUID) with this command

ls /dev/disk/by-uuid

once before I plugged in the drive and once after to see which uuid appeared. Once I knew the uuid I opened the fstab file:

sudo nano /etc/fstab

which opened as

proc            /proc           proc    defaults          0       0
/dev/mmcblk0p1  /boot           vfat    defaults          0       2
/dev/mmcblk0p2  /               ext4    defaults,noatime  0       1
# a swapfile is not a swap partition, no line here
#   use  dphys-swapfile swap[on|off]  for that

after /dev/mmcblk0p2 I added the line

UUID=44916713-0138-40f9-a7de-68266894bd20 /home/pi/RetroPie/roms auto defaults 0 2

this line is the UUID found in above, then the directory I want it to mount at, auto means automatically decide the filesystem, defaults is the default rw access (and some other stuff), 0 means don’t backup and 2 is the order for error checking. (See https://help.ubuntu.com/community/Fstab for more details).

Next you need to delete the current contents on the /rom/ directory (make sure you have backups!!) so that it is empty – mounting devices needs to have empty mount points. I used WinSCP as it was easier than using the command line.

Once the /rom/ directory is empty you just need to tell the system to remount the drives with

sudo mount -a

if you then type df -h you should see something like

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        15G  2.7G   12G  20% /
devtmpfs        364M     0  364M   0% /dev
tmpfs           368M     0  368M   0% /dev/shm
tmpfs           368M  5.3M  363M   2% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           368M     0  368M   0% /sys/fs/cgroup
/dev/mmcblk0p1   57M   20M   38M  35% /boot
/dev/sda1        59G  3.8G   52G   7% /home/pi/RetroPie/roms

Maybe not the best way but works for me. One word of warning you have to unmount the drive manually if you want to take it out! Without doing it you will most likely end up with errors or data corruption. If the Pi is off then there is no issue taking it out.

Although I formatted the drive to ext4 there is no reason why you couldn’t format it as FAT and then you could still access it with a Windows PC to.

Not sure if this helps but was my solution :D

[quote=115399]all I’ve done is point the es_systems.cfg to the USB drive, seems to work well enough for me, and it’s less hassle than creating symlinks. imho

also I did manually create all my gamelists so I have all artwork in the rom folder

I’ll probably go back to just doing it that way. I was attempting to standardize the way it works on my pi and one I’ve worked on for a friend. The symlinks are what I came up with so that I wouldn’t have to tweak anything once I copy my image for my friend.

You should be able to connect up to 4 wireless xbox360 controllers to one usb receiver. If you have already enabled the xbox driver, then by default two controllers will already be enabled. Simply sync your second controller to the receiver then map the buttons in emulation station just like you did for the first controller. The lights around the xbox guide button should even light up to correctly show which controller is 1st player and which is 2nd player.

[quote=115347]i go one step further and symlink the entire roms directory, so i just have to do it once if i reinstall. i copy all the ‘default’ roms to my USB stick beforehand, and use the same filestructure[/quote]

i am gonna upgrade to the new retropie version , editing the cfg took for ever this is so much faster and will avoid issues with gamelist.xml also , so ill be doing this , dont see how some thing this is not fast …….u write that one line into your terminal as apposed to editing each system in the cfg

all I’ve done is point the es_systems.cfg to the USB drive, seems to work well enough for me, and it’s less hassle than creating symlinks. imho

also I did manually create all my gamelists so I have all artwork in the rom folder
