This thread: https://retropie.org.uk/forum/topic/22392/lr-atari800-5200-artifacting-basic-and-other-guidance and the accompanying github repo with the script (https://github.com/raphkoster/lr-atari800-runcommand-onstart) maybe qualify?
The ResidualVM team has recommended the following changes to the script to build from source:
function, recompile ResidualVM. Then, modify the +Start ResidualVM.sh script to call
ulimit -c unlimited
so that it produces a core dump on crash.
Do you have anything to add, @mitu ?
Here is the solution I found :
1/ In the file /home/pi/.attract/emulators/Multiple Arcade Machine Emulator.cfg :
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"
@Banci Yehor's guide to the fix is posted. Each line he typed out you will type out yourself step by step, each break in the line signifies a submission.
sudo apt-get update -y && sudo apt-get upgrade -y && sudo reboot
sudo apt-get install git
his fix is the :
sudo ./retropie_packages.sh 833 depends
sudo ./retropie_packages.sh 833 sources
sudo ./retropie_packages.sh 833 build
sudo dpkg -i libsdl2-2.0-0_2.0.10*.deb
after this is done, you head into the setup as normal and launch. I followed his guide myself and it fixed my problem
@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.)
@DieKatz that sounds like something that could be configured in each game's service menu.
(so i guess you'd have to connect a keyboard to press left and right arrows at the same time)
@marcoabm Raspbian on a pc is untested, but we can't help without more info.
Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first
You will need to provide a full log.
I figured but wanted to double check if there was anything else i could download in the mean time. I wanted to avoid manual splash installs if I could help it. Thank you for the quick response and all you guys do!
@DieKatz I just wanted to say thanks for noticing this problem. While playing Sonic 3 on my gpi I noticed that some of the sound effects weren't playing at all. I could never figure out what the problem was. It was the same stereo/mono issue as you were having. So thanks again!
