I hold the Start button, which I set somewhere doing the initial setup, but now I'll be darned if I can find where that was. Now that I'm thinking of it, it could be that I set that in RetroArch without really paying attention, which would explain why this is happening. heheh

I recall seeing something in EmulationStation, but not being happy with the options. I'll take a look again.

Adapter seems to be working great, tried out some more games over the weekend and I'm loving it so far. I was also able to map the table of hotkey combos (updated above), except the "Input State Slot Increase/Decrease" triggers at the same time that I go to Save or Load which is mapped to D-Pad right/left.

All retroarch.cfg:

input_state_slot_increase = "right" input_state_slot_decrease = "left"

N64 retroarch.cfg:

input_state_slot_decrease = "nul" input_state_slot_decrease_axis = "-3" input_state_slot_decrease_btn = "nul" input_state_slot_decrease_mbtn = "nul" input_state_slot_increase = "nul" input_state_slot_increase_axis = "+3" input_state_slot_increase_btn = "nul" input_state_slot_increase_mbtn = "nul"

-3 and +3 are C-Button left and right. If I set the All config to "nul", they won't work in any other emulator, correct? Should -3 and +3 be mapped to input_state_slot_increase/decrease instead of the ones with "_axis"?

That being said, you should try one of the other MAME emulators - Mame2003 has mouse support and RetroArch seems to detect your mouse. As a plus, it supports absolute pointing devices.

@Efriim

Thank you! This fixed it. Player 2 is not set up yet as I am waiting for the second dolphinbar to arrive from Amazon which is tomorrow :)

@traptedmind - Thank you for posting this! The googledrive link appears to require access. Can you post the contents of the .cfg file to the thread?

Thank you!

I also wrote this once:

If you wanted to compare. :)

Thanks for the update, it's interesting to follow your way to a working solution.

Yeah, it seems that it is a kind of game of chance to get the right BT controllers for the Pi, may it be that I was lucky or you and @gpmcty were unlucky.

And yes, it seems to be either direct connection without the home key, or using an adapter. Ironically, I'm fine with my adapter although I don't use the home key anyway. :)

I figured it out (Wii U), thank you so much!

@sony_simon my compatibility is far better in lr-mupen than the standalone. I get so much lag and many games just black screen in the standalone.

I got mine working as well, the trick, I think was to copy in the ini file (changing the name) and let the config file generate it's own information based on the ini file (device id etc). I did set the number to 0 (full manual) for the controller, but it doesn't seem to matter as it changes back automatically once you launch a mupen64* emulator.

The controller will only work in mupen64 emulators though, so I may still return the adapter for something better. N64 is SOOOO much better with a real N64 controller though.

Not sure why this failed for me the first time, I think by taking in the cfg file I corrupted something.

@NoOddJob as @polish-potato said. On any mayflash adapters i have used, player 1 and 2 are backward. If that
isnt it then re set up your controller. Write down what numbers all the buttons are. Now open up the

/opt/retropie/configs/all/retroarch/autoconfig/

folder. Now find the configs for your controllers. Verify if if the numbers match. If they do then run

sudo jstest /dev/input/js0

Now push the buttons and verify if the buttons match there. If they dont, then change your config file to match the jstest.

Yeah I got mine as well and besides no random button presses, the controllers are also much more responsive, which made me forget about really needing wired controllers for certain games!

@mitu Thanks! It worked. I didn't have to re-install the lr-beetle-Saturn emulator, but rather run an update after deleting the config file. thanks!
