I don't know if maybe the retropie images are thought to be played on 16:9 monitors?

RetroPie can use all sorts of resolutions, it's not a problem here. It was probably - badly - configured to use an incorrect aspect ratio, ask your friend's friend. We can't help you here, since we don't know what and how it's configured.

Downloaded, installed and good to go! Thank you very much!

I had an issue almost the same as this. I have a pi4b with a 7” touchscreen. When I plug it in to my tv it starts fine color burst and command line show fine on my tv and the 7” screen together, but as soon as emulation station starts the picture goes away and only the sound comes through the TV. If I go into command line or pixel desktop the picture comes back on the tv. After a couple weeks of frustration I figured out if I take the power off the touchscreen everything will work perfect on my tv.

@mitu I've enabled both the options u showed in your post. It successfully. I was quite baffled because I saw the the Dt overlay option twice in the end of my boot config.

Thank you for your help

@Chronicomos Post the details requested so that further help can be offered.

It turns out that md_lbl and md_ need to have seperate size values for the "X" for some reason... it seems to be fixed now:

Most of the themes are not designed for a portrait mode - but you can try some of the 4:3 and CRT designed themes. I remember one them ( crt-centered ) had a simpler layout, with video on top of the gamelist, which would maybe fit the bill.

EDIT: you can run the theme-gallery from the Configuration/Tools->Emulationstation to get previews for different themes, just to see how they fit on your screen.

@gordonfreemanjr do you have any other controllers plugged in? Did you map your keyboard as a controller? It may be worth going into RetroPie-setup and resetting your mappings and then remapping just to see if that fixes the light issue.

@quicksilver, Thank you for your reply

@mth75 The patches added by the RetroPie install script work only with the branch/version specified in the script. If you'd like to get the latest dev version, you should also remove the .diff being applied.

@wild-snail you don't need to look at any code, just go to the retropie-setup menu and there should be an option there under configuration I believe

Take a look at https://github.com/recalbox/mk_arcade_joystick_rpi, it's similar to what you have in mind and it's already included in RetroPie.

@roslof I am showing my Genesis overlay files to be 1920x1080:

It's been reported a few times - seems like the PS1 USB controller doesn't get detected at all on a Pi4, for some reason.

@mitu I made a mistake in my testing, I beleive python-uinput my work

well, i though wrong it is still crashing for me. i ve tried batocera, retropie on raspberry pi and on pc via linux.. nothing, but it seems i m getting less frequent hung-systems, since it triggers now 1 out of 20 achievements i get at random. i ve tried all i could, i ve not found the solution. more is at the github page

@kam3chan said in How to install Sega Saturn on RasPi4 retropie:

I also looked under optional packages, but didn't them listed there.

It's not in the optional section, it's in experimental (as stated in the doc page). Even so, the core has some bugs on the Pi4 (graphical glitches) and for the moment it's not fullspeed.

@mitu thanks, that's it. I forced the hdmi group to 1 and mode to 16 to get 1080, and now the menus appear on the screen.
