@mitu yes

I have pretty much the same issue. :(

@masinad said in 8bitdo bluetooth controller and ROMs slowly loading:

Or where to look for information?

Seems like this issue. Try pairing the controller in Switch/Android mode instead of Xinput mode.

@mitu
I'm not sure. Wouldn't I have done that when I got the first Playstation controller working?
I ask because I don't really know. I followed a YouTube video directions to get the first dog-chewed controller working (not really knowing in detail what I was doing). One dog-chewed Playstation controller does work with RetroPie now.
I can see the other controller in the "Registered Devices" (both controllers, at the same time actually). I just can't switch between them, or better yet - get them both working at the same time.

-- But -- I did get it working just now.

I think the controller itself was locked up. I pressed the reset button on the bottom of the controller and it now works. In fact, they both now work at the same time. This is awesome!!

Please can you try out https://github.com/RetroPie/RetroPie-Setup/pull/3273

@darkwriter shoot! I just saw this. I had the exact same problem with my sn30pro controllers. Start+B for USB. I wish I had been here yeasterday to post. The manual gives zero clues about this. Glad they work now.

@messy in which screen/menu are you seeing the "you can unplug the controller now"? Is it on the "pair register bluetooth device" after going from EmulationStation > Bluetooth menu?

I've managed to plug 5 controllers via Bluetooth but never gone beyond that. Honestly donno if we noticed any lag or whatever, but this was on an older pi3b, which I think has weaker Bluetooth.

Depends how fussy people are, if they just want to play bomberman and have a laugh, I doubt they'd notice the lag. If they're hardcore online gamer types, maybe go for usb controllers and a hub.

In terms of games, the pc engine has capability for 5 player, but it's just bomberman which you've already got covered.

Look for a micro machines j-cart ROM on megadrive, that's 4 player I think. Also arcade beat em ups are fantastic 4 player, Simpsons, turtles, X men (6 player!), There's tons of them but I can't remember them all.

Edit:- just use this list for games btw, it's pretty exhaustive:- https://retropie.org.uk/forum/topic/4336/list-of-retro-games-for-4-players

Experiencing the same issue since updating to 4.7 (pi 4)

Previously I had working bluetooth but it seems to be messed up since the update.

I also tried removing bluez and reinstalling but now cannot see any bluetooth devices when scanning .

What's the fix guys? Would prefer to not re-image my SD card!

@rotopropjet

Thank you so much for sharing this solution! This was an easy fix and works for me too.

@redmarsbluemoon Yes, stock Raspbian. No need for userland ds4drv :) Imperceptible latency atlhough I've never measured it, I can easily play even games like Street Fighter II.

Try updating your packages/kernel? apt dist-upgrade and rpi-update.

Also be careful about interference from other wireless sources (Wi-Fi, other 2.4 GHz devices)... Maybe try moving things around and seeing if that helps. Best of luck.

I GOT IT WORKING!!!

Good Grief.....in the end I used the PS3 driver and what made ti work was, just after registering the device a window pops up saying you can now unplug your cable.

At this point, I unplugged and paired the controller and THEN with the keyboard moved back to the main menu to configure it.

Trying to pair the device at ANY other point during the process and it doesnt like it.

Have rebooted and the device still conect and works so it seems stable :D

Cheers for the help.

@lostless Got it, didn't realize I had to do this from Retroarch while playing the game. Thanks!!!

Just wanted to say Thanks for this question and answer. I had been struggling to get my 8bitdo Ultimate Wireless controller working in the games also and it turned out to be the same issue.
Adding /opt/retropie/configs/all/retroarch-joypads/8BitDo_Ultimate_wireless_Controller.cfg from https://github.com/libretro/retroarch-joypad-autoconfig/blob/master/udev/8BitDo_SN30_Pro%2B_BT_B.cfg worked.

As a total RetroPie/EmulationStation/RetroArch newbie, how is anyone supposed to know that they needed to manually add these controller configs? Is it supposed to be an automated system that's just not working correctly because I never saw any documentation anywhere that pointed users to the libretro GitHub.

Please post some details about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
