Hello, I am trying to build kind of a custom loader that the user can choose three games from instead of having the whole emulationstation menu to contend with, this is something that I am building in the godot game engine to port over to linix with the godot emulator and run on the pi. I am running into a little road block with changing games on the fly, as the emulator for godot will be running a "game" and when the user selects a game it will switch over to that one. I have my single-game boot working fine via run command, and I tried using this script https://pastebin.com/jmNJxMcJ to kill the game, but it seems it just looks for a running emulator, which it does not find.

Any simple commands on how to switch over from one game too another on the fly like this?
Much appreciated.

The script you linked assumes the program/emulator is started by runcommand, which is not the case here.
Find the process corresponding to your game/emulator with ps -ef and then use it's name to stop it with killall <proc_name>.

Alrighty, I gave that a shot and it gives me a list of processes and PID's but not names if I am reading it correctly, here is a pastebin of the process list, https://pastebin.com/4cGwJvUe I think the process im looking for is 508?

Thank you,

mitu

Sorry, I'm a bit confused - I thought you'd be running your Godot based game or custom loader ? Your process list shows an arcade game started from EmulationStation, the standard RetroPie front-end.

I think the process im looking for is 508?

No, in the example list you'd need to stop retroarch, which is started from runcommand.

@mitu ah sick that worked to kill the game, here is the pastbin for the godot-engine, im assuming i should try killall godo-engine?

@mitu sorry for the double post, I see the paste cut off some of the output, here is an updated pastebin https://pastebin.com/BnNU3EEM

@mitu think i got it, used the following and got back to command line:

ps -ef | awk '/tester/ {print $2}' | xargs kill

That would catch only when you run the tester.zip rom, it' better to match on godot-engine if the name of the process (frt_3.3.2_pi2.bin) has such an obscure name.

@mitu ah perfect that worked too, thank you very much!
