runcommand-onstart and -onend equivalents for Batocera?

Amplifuzz

I wrote a RetroPie bash script that's called from runcommand-onstart.sh, or can even be renamed as runcommand-onstart.sh and run. I'd like to make a Batocera version of it, is there an equivalent feature of being able to call an external .sh script from the runcommand script right before launching a game, and optionally to call another .sh script upon exiting it?

Thanks,
FZ

nice. it is something i wanted to add for an odroid feature.
i will post here once done. it should be done quickly (for the next release).

Amplifuzz

Thanks! To work with my use case the script should be able to be called after any video mode switching performed by Batocera (I've seen a runcommand.sh file with lots of if-then-elses about switching video modes).

Amplifuzz

Any news for that feature, now that you're in RC phase for 5.21?

Thanks 🙂

You can easily do this on your own by editing es_system.cfg, if ROM is loaded

<command>/path/to/runcommand-onstart.sh; python /usr/lib/python2.7/site-packages/configgen/emulatorlauncher.pyc %CONTROLLERSCONFIG% -system %SYSTEM% -rom %ROM% -emulator %EMULATOR% -core %CORE% -ratio %RATIO%; /path/to/runcommand-onend.sh</command>

Make the two files executable and your are done. You can also parse %SYSTEM% %ROM% ... parameters to this.

it is still in my head. but several things i would like to do quickly to unblock some people working on the distro first.

Well, following cyperghost's instructions I actually made it work, so no need for that urgently anymore unless you want to provide some kind of standardized method in the future. I'll make an official forum announcement once I release it properly, should be soon.

done for 5.23

I am always astonished as this has functioning long time ago.
As you have /etc/init.d/custom99 that calls /share/system/custom.sh
I was using this in Recalbox even before, and with inside custom.sh

#!/bin/bash

start() {
python /recalbox/share/myscripts/.......... &
}

stop() {
python /recalbox/share/myscripts/.......... &
}

case "$1" in
start)
start
;;
stop)
stop
;;

This is not the point and you misunderstood the feature.
S99 custom will load only twice - first run during startup and second run by shutdown/reboot of the system.
But in 5.23 there will be some "event" scripts if you start an emulator and if you terminate it.

You can see here PR 757 GITHUB that was merged with PR 768

For startup an emulator you can configure gamepads or sync savestates or automatically scrape the ROM or make a screenshot of the game after 10 seconds .... There are some usecases I can consider.

Yes, you are right, my fault. I was misunderstanding that the feature should be available at start or stop from a program. But also, features like this may have the side effect to slow down if you allow it for every game. No ?

Dragu I'm not sure what you mean with slowdown. Usually the scripts are intended to do some actions with if-then clauses. So this needs some time .... I guess 0,02s per script call.

Slowdowns of the emulator itself? No surly not if the scripts are coded properly and do not init some processes in background.
