RetroPie Boot into a Single ROM

[Healy_um]

@mediamogul Sure it's:
/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS gba ~/RetroPie/rom/gba/Pokemon Fire Red.gba && emulationstation

@Healy_um Ok, this might be crazy talk, so you might want to back up your system if you haven't already. But what if we tried this:

I believe that ES is launched from the following: /etc/profile.d/10-retropie.sh

That file looks like this:

   if [ "`tty`" = "/dev/tty1" ]; then
            bash "/opt/retropie/configs/all/autostart.sh"
   fi

What if you revised it to this:

   if [ "`tty`" = "/dev/tty1" ]; then
            bash "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-gpsp/gpsp_libretro.so --config /opt/retropie/configs/gba/retroarch.cfg %ROM%"
   fi

This would stop the retropie from starting up ES and start up lr-gpsp instead. Now my only question is will it still look to your autostart.sh to start the Pokemon rom? Not sure you can call out the rom in the code above?

@mediamogul am on onto something here? or way off base?

@Healy_um

@TMNTturtlguy's idea sounds interesting and you might also try changing your command to:

/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS gba ~/RetroPie/rom/gba/Pokemon\ Fire\ Red.gba && emulationstation

@TMNTturtlguy

Ok, this might be crazy talk

That's the best kind of talk.

[TMNTturtlguy]

@mediamogul hmmmm....looking at my code more, we are telling it to launch lr-gpsp and for lr-gpsp to look to retroach.cfg for how to run the emulator. This will get us to the emulator, but not rom.

[mediamogul]

@TMNTturtlguy

I believe you'd just replace %ROM% with the full path to the ROM, adding a backslash wherever there's a space.

[TMNTturtlguy]

@Healy_um If you are up to it, give this a try, go to: /etc/profile.d and open this file in notepad ++ 10-retropie.sh

Replace if lines with the code below:

 if [ "`tty`" = "/dev/tty1" ]; then
        bash "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-gpsp/gpsp_libretro.so --config /opt/retropie/configs/gba/retroarch.cfg /RetroPie/rom/gba/Pokemon\ fire\ Red.gba
 fi

Let us know if it works!

[tikiandskull]

Maybe that can help link text

[TMNTturtlguy]

@tikiandskull I think the link you sent just tells users how to enter the mame gui screen by hitting tab. I read through the post and i do not believe the poster actually tells anyone how to boot directly into a single game. Thanks

[Healy_um]

@mediamogul It worked!!! Thanks everyone who helped :) really didn't expect to get this working so fast! Thanks again all

[mediamogul]

@Healy_um

I'm glad to hear it. For the benefit of others who might follow along behind you, can you specify which tactic worked for you?

[Healy_um]

@mediamogul I've just edited the first post to include it :)

[mediamogul]

@Healy_um

Nice! Glad to see you're up and running.

[TMNTturtlguy]

@mediamogul nice work on the solution! much easier than mine was

[mediamogul]

@TMNTturtlguy

I'm always thankful when an easy solution pays off. More often than not I usually find that I've blown thrown 72 potential easy solutions, when a more complex approach would have ultimately saved time.

[LinuxArcadeGuy]

this is the line that works:
/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS capcom ~/RetroPie/roms/capcom/sfiii2.zip

backup your autostart.sh by duplicating it to autostart.sh.bak in WinSCP

customize to your own directory structure and rom name omit spaces or use \ like: Street\ Fighter\ 2.zip

@tmntturtlguy question that is right up your alley... looking to run a rom directly from main ES menu, versus opening a directory list... is this possible, thru my research I have found no way to do this, and a few nay-sayers...

What do you think?

Emulation Station is open source, so of course it could be done. However, you'd have to add the basic functionality for it first.

What exactly do you want to do ? You found a way to launch a single ROM on boot, if you want to go back to ES, just add the ES start command to the autostart.sh file, right after the runcommand you're using.

[mediamogul]

@mitu

I believe he's wanting to launch an item by selecting a system heading from the carousel. The practical uses would be pretty limited, but if memory serves, people are usually looking to launch Kodi directly without selecting a launch script from the resulting directory.

Hi. Having some problems making this work. Trying to boot directly into a2600 and the legendary E.T. However, although I made the changes, the system still boots happily to ES. Weird. Here's my changes to /etc/profile.d/10-retropie.sh

"/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS atari2600 ~/RetroPie/roms/atari2600/ET.bin"

Thanks for your help in advance :)
