Retropie 4.6 and 4" LCD screen

How about the one right below it? max_framebuffers?

You should enable that also.

display_rotate=3
to
display_rotate=2

Your screen is basically a mobile screen, so without the proper rotation the other resolution options are probably invalid. Try removing the rotation configuration first and see what comes up. If you're not interested in the touch abilities, you can probably remove the last line.

OK rotate commented out, almost ready to try again.

...and I comment out this one? Yeah I don't care about touch support
#dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900

It worked, thanks so much for your help!

The only remaining issue is that the interface is in portrait mode instead of landscape. I'm not sure if there is a fix for that within RetroPi? I found this thread for Mame &

https://www.reddit.com/r/Arcade1Up/comments/bv7lai/rotate_screen_from_emulationstation_to_use/

But I cannot find the path to -Retropie setup > Configuration/Tools > autostart > Manually edit autostart.sh which he said he changed the orientation in there.

Any ideas?

@avalkauskas Open RetroPie Setup from the RetroPie menu, this is where the modification should be made. You'll probably need also the parameters for specifying the width/height and that's just for EmulationStation. You'll need to apply rotation to the emulators' screen.

So when u get to the menu, do u go to retropie config? or do u press start to have the options including quit ect. and the option should be there?

mitu

@Madara-Uchiha by default, in EmulationStation you have a 'RetroPie' system included, with various menu option - one of which is 'RetroPie Setup'. The other menu that you get when you press Start is the EmulationStation menu.

Ok I'll try that.

So now I understand, but the thing is, after u get to retro pie menu, there is a bunch of things that I don' know about ( resetromdirs,samba,bashwelcometweak... Etc.) So what would i go on from here? I'm completely lost.

@Madara-Uchiha I suggest you start with https://retropie.org.uk/docs/First-Installation/.

Any reason you're using 2 accounts instead of one ?

Madara Uchiha

Oh, I'm avalkasukas's son. That's why it looks like someone is using two accounts. I checked out the link that you sent... I already knew about all of this. It's just that when i went on retro pie config, I don't see where u can change the orientation to landscape mode.

I did the initial setup, boot troubleshooting, and my son is working through the software configuration (and game installation). :) Your help has been great, because it's our first project like this, and my son has learned a lot about file systems, images, configs, boot scripts, etc...

There's no explicit setting for that. If you want to rotate EmulationStation, then you need to modify the autostart.sh file and start it with

emulationstation --screenrotate 1 --screensize 800 480

That will rotate the screen 90 deg, if you want to rotate it 270 deg, then use --screenrotate 3.

For emulators, you should stick to using RetroArch based emulation (the lr-... emulators) and modify /opt/retropie/configs/all/retroarch.cfg to add a line to rotate the display:

video_allow_rotate = "true"
video_rotation = "1"

That will also give you 90 deg rotation, try 3 for 270 deg. Match them to the rotation settings applied to EmulationStation.

Unfortunately, the screen console will not be rotated, so the RetroPie setup script and the Runcommand launch menu will still appear normally. You can disable the Runcomman launch menu if you wish.

All right I'll try that!
