Using custom script that is not runcommand.sh does not work

[RetroFloppy08]

@Folly If you look at the initial post, you can see the system entry.

Is that all you added ?
You will need to add much more to get it working.

So you have 2 choices.
Make a module-script like the example I gave you earlier , or do all the setting manually.
You can have a look here on how to do it manually :
https://retropie.org.uk/forum/topic/28462/tutorial-handheld-and-plug-play-systems-with-mame

And replace mame or emulator with your script and no need to use some retroarch.cfg.

@Folly Hmm. Seems like I've got a lot of work to do. I'll let you know how it goes.

@RetroFloppy08

Can you filter all the nonsense and pick the correct things for yourself ?

[RetroFloppy08]

@Folly I can certainly try. I'm seeing some key things already, for example lines at the end that use the %ROM% argument to load a file from EmulationStation.

@RetroFloppy08

Ok, good luck.

Try this first, otherwise I recommend you to make a module-script.
Once you know how, then it's the easiest way.

@Folly These are the lines I have narrowed down. I have a feeling they're wrong, so if they are, please tell me.

@sleve_mcdichael What argument am I supposed to attach to the command to load the filename?

%ROM% in the <command> string is used by EmulationStation and is replaced by the actual rom file you've selected. So for example if your <commamd> is bash /test/script.sh %ROM% and you select the game "Foorio in Foo Land" for the "Foo Bar Entertainment System" then ES is going to run:

bash /test/script.sh "/home/pi/RetroPie/roms/fbes/Foorio in Foo Land (USA, Zanzibar) (Rev B).foo"

Your script will then need to parse this as $1 or, "first argument."

I wonder if the spaces are maybe tripping it up. Try wrapping $1 in quotes, like "$1":

[[ "$1" == *.chd ]] && /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx "$1"

...or try "$*" ("all arguments") instead of "$1" (first argument) (still in quotes).

Not sure what you are doing with this.
My script works, but not for your purpose.
The module-script is just an example, if you want to use it you to completely rewrite it for your needs.

My advise was to make a custom system manually first.
If that doesn't work we can talk about making a module-script.

@Folly I've actually gotten the script to work. I reworked how the if statement is processed, and it works like a charm. Instead of isolating the extension (as initially suggested by @sleve_mcdichael) I instead told the program to read the last 4 characters of the filename. It works now, all I need to do is make more discs with different files, and add some else if statements. I'll post the script once it's finished.

@RetroFloppy08

Good work !
Curious what you made ;-)

[RetroFloppy08]

@Folly @sleve_mcdichael Alright, it's done. I present to you the script to load games based off of their filenames. This is the version I have, and it works very well. The selection is limited, but the good news is you can select for yourself what file types are supported. Have fun!
