this sounds a lot like the problems i am having. i have not moved to UAE yet.
seeing that they said Amiberry was the easiest one to setup.

Problems with it after getting it all worked out and setup then getting the Amiberry installed with the installer "Manage optional Packages" so now have Amiga folder showing up to put the games .LHA E:\retropie\roms\amiga with a jump drive
and putting the kickstart files in the jump drive E:\retropie\BIOS
so all seems good i looked at the files on the Pi and they seem to have copied over good and in the place it said they should be is there another place to put them???

but when i try and run a game.

it goes to a black screen and then winks back to the pick a game screen.
if i keep clicking on the A key it loads up a screen "System: Amiga" asking to select "default emulator" ES, ER,
VE, FE, FR, X, Q.
so when looking "ER" at Bios the names to not match the ones i uploaded. thinking it would be named the same as the ones uploaded.
not sure if this is the problem. do i need to do something other than just putting them in that folder???
(( Please help)) i seen something that the updater is not using the newest one will start looking at that.

my system is a Raspberry Pi3 B+ in the USA.
Hisense 4 K HDMI tv
XBox corded controller. Keyboard and mouse.
have been doing like the video said using the USB jump drive to move files over. "Raspberry Pi 4 Retropie - Amiberry Setup MikeyGRetro"
and use many other videos to help with setting up Retropie on the Raspberry Pi 3b+ "RetroPie 4.8 Setup and Install Guide for the Raspberry Pi" Wagner's TechTalk.

i have had UAE for Droid on my phone for 10 years i think. with the Amiga forever Kickstarts. but made a cool 3D printed Amiga case for my Pi 3b+ and wanted something i could use on the TV and the kids could play.
i do have Amibian working on another flash card on the Pi 3+ but just not as easy to use as the videos said RetroPie is. and this would be good. have seen some info on the site saying need to use the numerical updater seeing the auto one is not working right??

Self-answering...the solution, of course, is to turn on focus mode, something I'd never heard of before today. Live and learn. :)

@dch It seems you're using an older RetroPie version and from what I see in the Docs, UAE4ALL doesn't seems to properly support joysticks.
Try to update to a more recent RetroPie version and use Amiberry. If your gamepad works in other games/systems, Amiberry should be able to read the configuration created by RetroPie and use your gamepad.

YAY! got it working thanks to https://retropie.org.uk/forum/topic/18409/guide-getting-emulationstation-to-work-with-fs-uae

Had to install fs-uae manually first because of the gpg error then try to install with retropie-setup then follow the step above

All you guys rock :)

Time to go shoot some guys in Walker

@cacrlhungus74 This is old and maybe you already resolved, but i found saving config file under Amiberry you could also save game-specific controller mapping.
Althought i can only achieved mapping some keyboards commands (like F1) on controller shoulder buttons, which seems reasonable considered frontal buttons are needed for Cd32 games.

@SpudsMcToole I’m new to Amiga emulation... Have been trying this but it doesn’t load as seems unable to load the right rom

@spudsmctoole It did :)
