@dash-dot I bought the adapter because for the life of me, I couldn't get my controllers paired with the bluetooth on my pi. I tried everything. Some people have had luck pairing them, but unfortunately I was one person who couldn't get the generic ones to connect. I leave my pi in one place all the time, so I don't mind having the adapter at all as long as my controllers work ! :-)

EDIT: I didn't have to calibrate anything. Plugged the adapter in and synced my first controller and the other ones followed suit just by turning the controllers themselves on. No other messing around with them ! I bought this adapter as I was new to the scene at that time and didn't know what other dongles existed for the controllers to function.

I wasn't sure about that line as it looked to do the same thing, however when I pulled the lines from the main retroarch.cfg file, both lines were there so I put them both in "just in case."
Could be that the core looks at one line and retroarch looks at another, or that some lines found else-ware look for the other string.

@mitu I'm building a 2p arcade stick, with external 2 pads snes, I wanted to have the person choose what to use as a controller pad or stick, but I can not find a solution

Ok it looks like I have figured it out. Apparently I needed to edit the retroarch.cfg file that was in the arcade folder instead of the mame-libretro. Once I properly set the hotkey and the menu toggle buttons, I was able to bring up the RGUI menu and then consequently configure the rest of my controls. Thank you everyone and hopefully this will help someone else down the road. Mark as solved!

@sano This sounds very much like what I'm trying to accomplish! :)
is there a separate hid for sony clones? The controller is still being detected as "ShanWan PS3/PC Wired GamePad"

@herb_fargus It is, even the logo. \o/ Thanks!

@Fr3d You need to hold down the button for a couple of seconds. If you still have problems, open a new topic and provide the information asked in https://retropie.org.uk/forum/topic/3/read-this-first.

NES has button B configured as "0", while SNES has button B configured as "2". SNES's "0" is button X. That's why my NES B button does a page-down in a game list instead of exiting the list, as well as why inside a game the B button does the same as the A button (NES games only see one bit for each button, so "2" becomes "0", which is button A). :-)

"0" isn't A, so my logical thinking doesn't feel correct. :-) Anyway, in order to make things more clear, here are the two configurations:

NES controller:

input_device = "usb gamepad "
input_driver = "udev"
input_start_btn = "9"
input_exit_emulator_btn = "9"
input_up_axis = "-1"
input_a_btn = "1"
input_b_btn = "0"
input_reset_btn = "0"
input_enable_hotkey_btn = "8"
input_down_axis = "+1"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_select_btn = "8"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

SNES controller:

input_device = "usb gamepad "
input_driver = "udev"
input_l_btn = "4"
input_load_state_btn = "4"
input_start_btn = "9"
input_exit_emulator_btn = "9"
input_up_axis = "-1"
input_a_btn = "1"
input_b_btn = "2"
input_reset_btn = "2"
input_enable_hotkey_btn = "8"
input_down_axis = "+1"
input_r_btn = "6"
input_save_state_btn = "6"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_x_btn = "0"
input_menu_toggle_btn = "0"
input_select_btn = "8"
input_y_btn = "3"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

Hi,

Could you not read your SD card on a PC running Linux, or with a bit of software on Windows to allow you to read the microSD card, and get your ROM files that way; at least that would save you some work?

Although the horse has bolted, so to speak, if you're going to upgrade anything, always do a backup first. It is so much work to lose if you've built your own image from scratch.

All the best.

Ok solved deleting all configs

@rjotter Generally folks here don't like to help those who are using a pre-made SD image as the best source of help tends to the person who setup that image because who knows what they did with all the configs and setup.

BUT... you may need to look into using the xboxdrv?

I experimented with it at one point but never got it to solve my input issues. Turns out there were simpler issues at hand.

Update

For anyone else trying this, I tried many different combinations of drivers and commands/scenarios. Including cycling through all the pairing modes. The best I seemed to get it was by pairing it into "Android B" mode, and from emulation station I was able to get it to recognize as a keyboard, but it only recognized a single button. Strange.

@lostless Thanks dude for verifying ! Now back to gaming!! ;-)

@bogus Glad you got it solved.

I guess dual bluetooth controllers of differing makes/models are not supported?

I use PS3 controllers with no lag and just this past weekend I played on my cousin's box I built for him with no lag. He uses xbox360 controllers with a K-mart quality 3rd party usb wireless adapter. I think a lot of lag has to do with how the controller is made to work with Bluetooth and if there is luck or good support. I've even tried some discontinued 8bitdo Sn30 controllers that work fairly well but I feel like there is noticeable lag with them although it's not enough to alter gameplay once you get past it.

@icvaalmall84 I can get the controller to connect via bluetooth, but once connected it doesnt map or work. any ideas?

Do they make a Sega Genesis turbo 6 button controller with shoulder/triggers? I thought they did back when my 66mhz PC used to play Street Fighter and Jill Of The Jungle.
