Hello, check that the name of the bios is correct and respects upper and lower case letters. Also check that the bios are validated in the recalbox bios tab.
I closed the same topic opened here :
https://forum.recalbox.com/topic/34388/help-with-amiga-1200-and-bios-issue

Welp, I don't know how I did it, but I managed to fix the issue. it really was the recalbox-user-config.txt. I made sure to delete all my userscripts, pasted in this code in the user config: dtoverlay=gpio-fan,gpiopin=14,temp=60000 and connected my resistor wire to the corresponding GPIO pin and now it works exactly how I want.

I started noticing the fan was actually starting and stopping while the box was on after moving everything to a new SD card. I don't think it was the card that fixed it as I copied everything in both the recalbox and share drives to the new image, overwriting everything with my configs. The only difference is I removed the bash and python scripts I was experimenting with in the userscripts folder. The user-config still had the previous line of code and actually started working.

I still had one problem as I was still using GPIO 3 instead of 14, and the fan would stay on if I quit recalbox through the menu instead of a hard power down by holding down the button. Switching to GPIO 14 like I originally wanted and updating the code to match the pin fixed this, thankfully. Now I have a properly functioning mini fan that came with the case.

Tl;Dr;

If you buy a Geekpi case for Raspberry Pi 5, buy a EZ fan2 for it with some extra wires. Install the 5v and ground wires into pins 4 and 6 like the Geekpi instructions say, and add your new resistor wire to pin 8 (GPIO 14).

Set up your recalbox as recommended, doing the first time boot and setup so it creates the needed files.

Open up your recalbox-user-config.txt located in the root of the RECALBOX drive either on your computer or via a network.

Paste in dtoverlay=gpio-fan,gpiopin=14,temp=60000 in a free line.

#Add a comment line above the code like this to write down it's the fan control code if you'd like

reboot

And that should work. I will experiment to see if why it didn't work for me before might have been because I wrote 55000 for the temp and that was too low or not, but I'm satisfied with 60 degrees as a trigger.

I will also quickly mention that the EZ fan2 does fit in the rather compact case. Just tuck it under the board with the wires in an "S" shape.

I still think it would be nice if there could be a GPIO fan control menu in emulationstation like Raspberry Pi OS has, but I managed to work around it.

Thanks for listening and hope this helps someone in the future.

I have the same problem. I had a Raspberry Pi 3 that worked with my normal GPIO arcade controller, now I switched to a Raspberry Pi 5 and the controller doesn't work

I found this in the backup.conf:

emulationstation.pad0=03000000790000000600000010010000:DragonRise Inc. Generic USB Joystick

emulationstation.pad1=03000000790000000600000010010000:DragonRise Inc. Generic USB Joystick

Looks like recalbox gives both the same id. Maybe thats the problem. But how to change that?

@LefternHempfield Did you have any luck with this?

I've noticed that they work, but intermittently.. I have to restart the device, plug in and our consistently, and then sometimes and randomly, one or the other will connect. (I am using 2 controllers).

Re @feralshadow
It was a known bug on Pi5, devs brought a lot of modifications after the release of the experimental pi5 version. Beta-testers are on the way.

You need to put the 8bitdo Ultimate controllers into Linux mode before they will work with Recalbox. If it's a wired version, you do that by holding down the B button when you plug it in. If it's the wireless version, I believe you hold down home and B. The instructions for switching modes are in the little manual that came in the box.

@hobbystudent

Tried to make it work with RetroPie and Recalbox as well. No luck with manually adding drivers. Got it working with preconfigured RetroPie 4.8 but... I needed to recompile LCD drivers as well:
https://retropie.org.uk/forum/topic/35177/gamepi20-lcd-once-again-retropie-4-8-and-pi-zero-2-w

Had the buttons problem also. When I pressed D-PAD the menu was skipping three positions.

I'd prefer to make it work with 9.1 Recalbox, but things are as they are. There's no proper support from Waveshare.

Update:
Also occurs on another Raspi4 with a vanilla Recalbox installation. So it is a general issue.
When i use an older Xbox Wireless Adapter (the bigger one) it works for 30 min and then the controllers disconnect. I can reproduce that behaviour. The pairing button on the Wireless Adapter also doesnt work after that (LED is on but seems to be frozen). Only a reboot solves it. USB Cable works all the time.
