@arvis1 NEVERMIND, i found the issue. In this thread: https://retropie.org.uk/forum/topic/34661/solved-remove-pulseaudio-and-revert-back-to-alsa/3
The issue was that using purge on pulseaudio did not fully uninstall, so you have to go into the retropie setup as detailed in this guide.

@sheazer13 got it to start emulator and game but it is still doing the same things where it says missing rom files.

It still loads fine on emulation station though

I ended up fixing the problem on my own.

The issue was that Drastic and Retroarch were trying to render the resolution at 640W x 480H, which would cause squishing issues.

By adding in:

hdmi_cvt 480 640 60

Into the config.txt, I was able to give drastic another resolution to render at, solving the issue. For retroarch, I made the auto fullscreens resolution the 480W x 640H that the display was native to, which also solved the squishing.

Is the controller configuration saved in /opt/retropie/configs/all/retroarch-joypads ? Do you see a .cfg flie there for the controller ? If yes, can you post the contents of the file surrounded by code tags here, in the topic ?

@abj Thank you SO MUCH, I was super lost when it came to this but it worked <3

@umxp02 Hello thread from long ago :)

I ended up moving to Batocera with my Pi 4 and had no issues with screens at all. I eventually got a Pi 5 for Batocera.

My Pi 4... I repurposed it to run Plex, and don't need a screen since I can control it from my Mac.

Yeah this issue was a brain buster, so I'm happy I moved on.

@wtstreetglow1 Just letting anyone in the future know that after my research. Final Burn Neo games still go in the fba rom folder and mame 078 go in the mame-libreto rom folder

@13ooty

I'm also new to posting on forums so I'm sorry If my writing and information is sloppy xD

@sleve_mcdichael said in Oricutron key mapping - is it possible?:

It can be a lot to process. How far in before you got lost?

Look for an entry that represents your device. Scan for the line marked H: Handlers=, and make note of the event number. Example:

pi@retropie:~ $ cat /proc/bus/input/devices I: Bus=0003 Vendor=046d Product=c21f Version=0305 N: Name="Logitech Gamepad F710" P: Phys=usb-0000:01:00.0-1.2.2/input0 S: Sysfs=/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.2/1-1.2.2/1-1.2.2:1.0/input/input73 U: Uniq= H: Handlers=event0 js0 B: PROP=0 B: EV=20000b B: KEY=7cdb0000 0 0 0 0 0 0 0 0 0 B: ABS=3003f B: FF=1 7030000 0 0 I: Bus=0003 Vendor=046d Product=c315 Version=0110 N: Name="Logitech Logitech USB Keyboard" P: Phys=usb-0000:01:00.0-1.2.4/input0 S: Sysfs=/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.2/1-1.2.4/1-1.2.4:1.0/0003:046D:C315.0030/input/input74 U: Uniq= H: Handlers=sysrq kbd leds event1 B: PROP=0 B: EV=120013 B: KEY=10000 7 ff800000 7ff febeffdf ffefffff ffffffff fffffffe B: MSC=10 B: LED=1f

Truthfully? Here.

(But thank you very much for trying :))

Delete this, I just view the answer in one of my other questions.

@mitu yes, each controller works if it's individually pluged

@mitu Alright, that sucks to hear but guess i'll get to fixing it the physical way then. Thank you for the responses!

@dookieshooter You should delete/rename es_input.cfg and then re-install the emulationstation package, this would generate the correct es_input.cfg file. You'll have to re-configure your controls next time ES boots.

@bluecoffee said in Two MAME games, one works 2 player one doesn't:

Forgive my ignorance but how would I tell a single rom to use FBNeo?

You can use the runcommand launch menu to choose which emulator runs a rom.

Looks like the configuration is not properly saved, though it's not clear for what reason. Can you add more info about your setup, as asked in https://retropie.org.uk/forum/topic/3/read-this-first ?
Make sure your storage/sd card is not full.

@duglor

Just use hypseus, save yourself the headache.

Thanks you I'll give that a try.

@mitu Well, as always thanks for the help. I don't think it's underpowered given my new 3.5a CanaKit PSU made specifically for the Pi4 and it's a powered USB hub. But I can't rule out an unseated cable or something because now it's back to working correctly. I'm going to keep the USB HDD connected directly to the Pi, since if that isn't seen on boot, then it won't have access to the romsets which explains why they wouldn't show up, and if the USB cable to the hub got jostled then that would also explain why the gamepad wasn't detected.

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

Post your /boot/config.txt and /boot/cmdline.txt.
