partially resolved. i had a setting enabled that was preventing new games from coming in via the scrape options.

I see the problem.

The problem is you have enabled ParseGamelistOnly - which will mean it doesn't scan for roms and only shows items from scraped gamelists. Hence your roms are not showing up.

https://github.com/retropie/retropie-setup/wiki/FAQ

Parse Gamelists Only: If on, it will only read the roms you have scraped, so if you add any new roms it will not look for them unless you turn this back off. it is off by default.
also - are you aware any es_systems.cfg in /home/pi/.emulationstation will override the retropie-setup generated /etc/emulationstation/es_systems.cfg - you probably dont want that unless you are happy to maintain it manually.

Resolved the roms not appear.

I'm still dealing with being unable to set hotkeys on the controller.

Thank you for your help.

Thanks. The problem then is bad wiring or a fault as they normally map to different keys.

@markyh444

yep cool thanks

@daeks Interesting. I missed that line in your config (must've skim read past it) but it kinda makes sense. No idea why it was forcing the hotkeys to js1 though when you only had the 8bitdo connected as js0. I don't remember my config being picky like that when I setup my n64 to USB adapter for glupen

@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

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

@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?

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?
