@Ecks00 said in Help on how many controllers:

Hi i am wondering how many controllers can the RetroPie handle up to because i have a lot of 3-4 player games that i would like to play with my friends but every video and posting online i have seen only shows "how to configure second controller" and would just like to know if i can add in 3+ more controllers into this.

I've had 4 running with no problem. All different types. Sometimes all hard wired, sometimes hardwired with some wireless thrown in. Only problem is finding out (and fighting over) who's player 1, player 2, etc. (especially in Teenage Mutant Ninja Turtles -or "Hero Turtles" for you lame brits ;) where each player is stuck with their assigned ninja turtle.

@plwiatt The Pi detects player 1 as joystick 0 and player 2 as joystick 1. Have you tried just plugging into the other port of the adapter? From what you're saying, it looks like you've got the ports mixed up and are plugged into the player 2 port.

RetroPie has some systems flagged as main or core systems, and as you've now discovered, the Atari 800 and 5200 are not part of that group. Going through the menu you will find it, and many others, in the optional systems menu. That process will add the emulator and create the necessary ROM folders.

The Binary option is always the safest and easiest way to install an emulator. Installing from Source is more advanced and only needed if you're after a recent code change to that emulator, but you run a higher risk of encountering bugs.

I learnt loads! Thanks again :)

@aweiand unfortunately a lot of people have problems with using the wiimotes including myself. A couple people have stated they have it working without any real explanation of how. I just use a usb adaptor for the classic controllers

@Rion said in FBA and NEOGEO *.nv and *.fs files question:

bur for normal Fba

What's "normal Fba" ? You mean fba with non-neogeo games ?

Yes sorry i should have clarified that.

I'm using
https://github.com/libretro/fbalpha

I just moved out all the NeoGeo games from the Fba folder and put them in neogeo. Then using fba to run them.
So when doing that the *.fs and *.nv files wind up in the correct folder specified in the Retroarch.cfg file for neogeo.

Any insight @barbudreadmon on what could be the problem?

After a bit of playing around I managed to get the Pi Zero working - By updating all the packages and emulation station, it all boots up fine now. Problem solved.

Thanks

@dips52
EDIT: I'm assuming you're using lr-fbalpha (aka lr-fba-next).

my suggestion: undo the changes you've made on that file and then configure the mappings the way you like using the core input remapping method.

Thanks mates for your help!

Hardware specifications

RetroPie version: if i "git log" inside my repo I obtain:

* commit 88829054bf0cc54d5779704ac3e3c41a2d1eb1a0 (grafted, HEAD -> master, origin/master, origin/HEAD) Author: Jools Wills <buzz@exotica.org.uk> Date: Sat Nov 26 18:21:55 2016 +0000

I downloaded it via git clone https://github.com/RetroPie/RetroPie-Setup.git
Should I download https://github.com/RetroPie/RetroPie-Setup/archive/4.1.zip and install from that source?

One more thing! If I ssh to the pc I installed RetroPie to... Emulationstation START !!! :) But it isn't what I would obtain.. :) :) :)

Hello all my buttons are mapped by the GPIO pins. I followed a video on youtube to do it. But not sure how to map two functions together onto 1 gpio pin?

@eweek reinstall emulationstation using retropie_setup and you'll get the file again.

like, totally awesome build dude! :)

Seriously, that's one wicked arcade cabinet. Would love to see the components list as I'm tempted to do a similar idea !

@JHamz
Hmmm...check to see if your using "udev" & if not set to "udev"

RetroPie -> Configuration Editor -> Advanced Configuration -> Configure Libretro options -> all/retroarch.cfg -> input_joypad_driver (udev)

Here is what my EmulationStation mapping for my wireless X360 controller looks like:

nano /opt/retropie/configs/all/emulationstation/es_input.cfg

<inputConfig type="joystick" deviceName="Xbox 360 Wireless Receiver (XBOX)"> <input name="pageup" type="button" id="4" value="1"/> <input name="start" type="button" id="9" value="1"/> <input name="up" type="button" id="15" value="1"/> <input name="a" type="button" id="0" value="1"/> <input name="b" type="button" id="1" value="1"/> <input name="down" type="button" id="16" value="1"/> <input name="pagedown" type="button" id="5" value="1"/> <input name="right" type="button" id="14" value="1"/> <input name="x" type="button" id="2" value="1"/> <input name="select" type="button" id="8" value="1"/> <input name="y" type="button" id="3" value="1"/> <input name="left" type="button" id="13" value="1"/> </inputConfig>

Something else I read is to add a "sleep" command in the EmulationStation start script in /usr/bin/emulationstation
https://github.com/RetroPie/RetroPie-Setup/wiki/EmulationStation#es-doesnt-detect-my-controller-when-started-at-boot

Another thing I read was it can be an issue/bug in the SDL and here was the "hotfix":
http://blog.petrockblock.com/forums/topic/problems-getting-ps3-controller-to-work-properly/#post-119984

@cyperghost 900mhz is for sure minimum. 1000 is the best setting for over clocking my rpi1 b to alleviate lag. Also setting the sound latency to 48 in retroarch settings gets rid of the distortion. I cannot speak to how damaging over clocking is to this device, 1000mhz is an aggressive setting.
