Sure you can. Check the docs.
You can find overlays and launching images for many arcade classics in my Repo.

Please don't post links to rom/copyrighted material sites - https://retropie.org.uk/forum/topic/2/forum-rules.

@ricbritain Just of curiosity, how did you miss it, and how did you finally find it?

i don't think there's a good way to do this. if you do a custom resolution in retroarch that includes some padding it
a) won't solve the issue in non-libretro games/emulationstation, etc.
b) will need to be done for each arcade game as they have many different resolutions.

the only way i can see is using the overscan settings to add some overscan to give you a vertical border. eg: https://elinux.org/R-Pi_Troubleshooting#Big_black_borders_around_small_image_on_HD_monitors
you'd want something like

disable_overscan=0 overscan_top=20 overscan_bottom=20 overscan_scale=1

increase the 20 for _top and _bottom until you get the right amount of border.

however that will
a) mess up the aspect ratio of the games, making them look fatter. i guess you could add

overscan_left=X overscan_right=X

where X is the same as the number you're using above.
b) give you some pretty brutal scaling artefacts, since you're fairly low resolution to begin with.

maybe there's another way...

I ended up rebinding all the controls through trial and error. Seems like there is no logic behind the labels. But now it works.
Also, turns out the erroneous mapping was for player 2 as well, but I could copy the same mapping to player 2 after I had saved settings for the core.

@AmigaMoreThanCLi If this is the StarTech.com USB to M.2 SATA Converter, it only supports SATA M.2 drives.

Samsung EVO 970 Plus is an NVMe drive. It will never work in this board. You need a SATA M.2 drive.

@mitu i don’t think the pi3 is capable of doing 4k (as in, the driver won’t permit it). even with the mesa driver i’ve not had to set anything to get it to work on my 4k display - it ran 1080p by default

@daiana_75 please fill out https://retropie.org.uk/forum/topic/3/read-this-first

i would remove the pi from the case and run it caseless whilst you’re debugging. fans and cases are additional points of failure.

i would also ask these kind of general pi support questions on the raspberry pi forums as you’ll probably get better answers. you’re not at the retropie stage (and we don’t support pi4 officially yet)

@mitu
Yes thats what i get :
@roslof
I try everything u wrote but still no luck
thanks

@Rion
Got my emulation stuck on the reboot screen...
@meleu
i did try that one too but really seems that too many games list make the loading screen on the reboot longer

@bpcervantes We don't support 3rd party images. Use the image from https://retropie.org.uk/downoad and then add your own games as described in the docs.

Read the installation instructions for the MAME version you want to install - if you don't find it in the the software center, then you'll probably have to compile it or download a pre-compiled version.
Once you get it installed and running, then you can probably modify the Emulationstation configuration to add a new system for this new MAME version - something similar to https://retropie.org.uk/docs/Add-a-New-System-in-EmulationStation/.

It's already included (update). It's an optional install though so won't be pre-installed in the next image.

Yes lr-flycast is slower than reicast, and lr-redream doesn't start at all

Maybe https://retropie.org.uk/docs/FAQ/#how-do-i-hide-the-boot-text can help, the MOTD is mentioned there, too.

Have fun with Retropie. :)

Hello,

Here is the solution I found :

1/ In the file /home/pi/.attract/emulators/Multiple Arcade Machine Emulator.cfg :

executable /opt/retropie/supplementary/runcommand/runcommand.sh args 0 _SYS_ mame-libretro "[romfilename]"

2/ In the file /opt/retropie/configs/mame-libretro/emulators.cfg

lr-mame2003 = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame2003/mame2003_libretro.so --config /opt/retropie/configs/all/retroarch/retroarch.cfg %ROM%" default = "lr-mame2003"

3/ In the file /opt/retropie/configs/mame-libretro/retroarch.cfg

input_remapping_directory = "/opt/retropie/configs/mame-libretro/"

4/ In the file /usr/sbin/rgbcommander/rgbcmdd.xml , section MAME, place :

<emulator binary="mame-libretro" name="Multiple Arcade Machine Emulator" active="Blue" inactive="DimGray" arcade="1" retropie="1" retropiebinary="retroarch" reference="arcade">

5/ To continue using overlays (example for the game 1943)
Create the file 1943.cfg in the directory /home/pi/RetroPie/roms/mame-libretro/roms :

input_overlay = /opt/retropie/configs/all/retroarch/overlay/arcade-artwork/1943.cfg input_overlay_enable = true input_overlay_opacity = 0.900000 input_overlay_scale = 1.000000

and in the file /opt/retropie/configs/all/retroarch/overlay/arcade-artwork/1943.cfg :

overlays = 1 overlay0_overlay = 1943.png overlay0_full_screen = true overlay0_descs = 0

And the overlay image must be placed in /opt/retropie/configs/all/retroarch/overlay/arcade-artwork

6/ In the file /opt/retropie/configs/all/retroarch/retroarch.cfg, set the parameter config_save_on_exit :

config_save_on_exit = "false"

@RetroPieVin Yeah, I've had no obvious problem with rotating the video prior to starting ES, but I'm running very "low resource" games in this instance.

Like I said depending on which emulator you use it could do either. You could use a split screen mode like MAME2010 provides when you put anything in cocktail video mode or you could use a dip switch for rotating the entire play area for second player like MAME2003 does. You could also use a shader in RA to achieve a split screen affect for simultaneous two player action. (The shader option wouldn't just be for the second player though.)
