Great thanks for good feedback, and I really liked the video there @Shakz.

I actually got out and bought a better power supply and got rid of the yellow lightning bolt after I read your answers, however I couldn't find one that hosted a USB port rather than a fixed cable with a Micro USB-interface. I have now done a quick-and-dirty attachment of it to the PiNES but I'll try to find a better solution to be able to connect the power via a USB B cable since that will be better for transportation and general look overall.

However thanks again, I feel the subject is closed and I'll just have to find the proper gadget to handle it. :)

All the best,

:O) !!!!!!!!!!!!!
Many thanks for the info, I thought it might be that. Getting the system roms proved to be a bit of a sod. First ones kept giving me 'drive errors', but I came across a fuse package on Aminet and got the correct system roms from there. Watching 'Weed' right now... looks brilliant running on the big screen.

Thanks very much.

I am on pi zero and updated from 4.0.3 to the latest 4.1.5

at least I tried to. (with "update all packages").

I believe even the 1b can run RetroPie and emulate older systems. The 3b can emulate the Dreamcast, the N64, the PS1, the PSP, etc. to an extent. But you wouldn't be able to emulate those systems on the 1b.

Nobody? :(

Ok, I guess the folder structure must have been altered or something.
I cant even get the right settings when i start from scratch, and saves the configuration. As soon as i start a new game, its back to what I think is retroarch.cfg.
Dosent matter how many override/core specific options I tinker with.

f*ck it, I´m gonna go back to my old 4.1 backup image.

I'm having similar problems with Retropie. I'm using a Picade from Pimoroni that has its arcade controls mapped as keyboard buttons through their PCB, running on a Pi3. I'm trying to configure my setup with P1 using the arcade buttons, and P2 using a wired Xbox 360 controller. I have the keyboard configured properly, as well as xboxdrv installed and enabled. I'm crossposting from the below link in an effort to get some kind of assistance, so I apologize if something sounds out-of-context

I entered manual config lines into my retroarch.cfg file to correspond to player 2 (http://forums.pimoroni.com/t/multi-player-picade/1507, my cfg is almost identical to the one themattsearle pasted). If I do a simple restart, the P2 controller will navigate all retropie menus exactly as expected, but once I load any game the controller ceases to function (P1 functionality never seems affected, which is good) until I back out to the menu with P1, not even the ingame Retroarch menu functions. Also, every game that I start has a little popup yellow text message in the bottom left corner at the start: "Xbox controller userspace blah blah is not configured"

If I open the retropie menu and "Configure Input" for the Xbox 360 controller, Player 2 inputs in games work perfectly as expected, but it has the problem with controlling P1 and P2 simulataneously. If I delete the .cfg file named after the 360 pad in the /configs/all/retroarch-joypads (the only file in there) and restart emulationstation, I revert back to the ES menus working but ingame controls not for P2. I even tried copying the input_player2_ lines from retroarch.cfg into that xbox cfg, but nothing changed.

As a last-ditch effort I restored my Retroarch.cfg back to the original unaltered backup I made (just in case I tweaked more options that could be complicating things). That had no different effects so something just isn't working as it should. How is it possible that the P2 controls can be configured manually but the emulators just don't recognize it? I think when I get home today I'm going to do a full system update to the newest version and see if that makes a difference. I spent so many hours configuring my romlists, scraping for artwork and manually configuring things that I really don't want to start from scratch on a fresh disk image.

I feel like I can't win and it's driving me mad. There has to be something simple that I'm missing and I can't figure out what. I'm fairly new to Retropie and just built this cabinet a few weeks ago. I was hoping to bring it to a christmas party this Saturday to show off to everybody, but I really just want 2-player support to work with a minimum of fuss.

@Sturgy86 we need more info to help you. But first you should read this wiki page and see if you can solve it yourself:

Cheers!

@dankcushions

The devices report more than just a VID and PID number then, correct? Because you'll see different text show up for different controllers (like Mayflash, or RetroUSB, iBuffalo, etc), and the config files get named differently as well.

And I will run that command when I get home, thanks. I only have I think 2 different quasi-generic brands of SNES controllers at home now (maybe a third this weekend if it comes in) - gave the others away. I'll see what my Hyperkin Genesis says too as that one is also generic for some reason (think I have a Tomee? NES one as well). My iBuffalo we know is fine and unique.

nevermind, magically working now..

Just to clarify yes I have 2 USB ports on my Rasp Pi.

I reinstalled 4.1 on it yesterday and am currently copying a rom collection back over to it. I'll try to check tonight to see if they run smoothly or not.

@ljustino did you read the link above regarding romset versions ?

@KairosZenith

Nice! I'm glad it worked.

Actually I think the default is Mame4All. It does a better job at emulation but again...the controller issues.

Ok, managed to get all my controls on the correct sides, only issue I have now is I cannot have start and select working on both player 1 and 2. This also causes me not to be able to exit a game back to the main menu by pressing start and select. Any ideas ?

Same here. Checke the USB-ID with lsusb and added the line at the end of my config.txt. Still only one controller is found.

Is there a way to check if the USBHID is actually loaded? Something to verify/probe what is going on why js1 isn't available?

Using Retropie 4 on a Raspi 3.

AND THERE IT IS that elusive fix I have been searching for all this time!

@BuZz said in Retropie not showing two emulators I just installed (RESOLVED):

@Shizzmoney you have a /home/pi/.emulationstation/es_systems.cfg file - this is not created by default so I assume you copied the system one from /etc/emulationstation to customise it ? You will need to keep it up to date if overriding the system one in `/etc/emulationstation

@DorkVonWaterfall said in Pi3 won't connect to wifi:

i had a simmilar problem because i took another powersupply then i used to...

PS: some usb keyboards also dont work properly, so if the password is hidden with dots/stars you cant be sure you wrote the correct password

Is there a way to show the password to verify it is being entered correctly?

@Shizzmoney you don't need to copy it to add extensions. Just create a file /opt/retropie/configs/all/platforms.cfg with a line fds_exts=".nes .fds .zip" (with your extensions and update the emulator in question.

If we have a missing extension though it should be reported back to me :-)

@saikyo78

Ah, nice.
