Using custom script that is not runcommand.sh does not work
-
This may be some hard-coded thing, but using my own script instead of runcommand.sh doesn't work. This may be my own fault, but first I get "Permission Denied", then after adding
sudo bash
to the command ines_systems.cfg
it gives me "command not found" which I am stumped by. Is it something with the script? Can it not find the file? If someone could point me in the right direction, it would be greatly appreciated.Here is the script itself:
#!/bin/bash if [[ %ROM% == *.chd ]] then sudo bash /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx %ROM% fi
And here's the system entry:
<system> <name>Load From Game Disc</name> <path>/mnt/disc</path> <extension>.cue .cbn .chd .img .iso .m3u .mdf .pbp .toc .z .znx .zip .CUE .CBN .CHD .IMG .ISO .M3U .MDF .PBP .TOC .Z .ZNX .ZIP</extension> <command>/opt/retropie/supplementary/runcommand/loadfromdisc.sh %ROM%</command> <theme>disc</theme> </system>
Currently using a Raspberry Pi 400, with a USB cable I bought from Amazon and a charging brick, running Retropie 4.8, with a USB DVD drive and a PDP Nintendo Switch controller. No log file.

@RetroFloppy08 your custom script doesn't understand the
%ROM%
parameter. Try:#!/bin/bash if [[ $1 == *.chd ]] then /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx $1 fi
...if that doesn't work, it might not like the wildcard in your test string. I would use something like this to strip everything but the extension and test against that:
#!/bin/bash rom="$1" ext="${rom##*.}" if [[ "$ext" == "chd" ]]; then /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx "$rom" fi
-
@sleve_mcdichael Just to clarify: do these scripts account for the actual selected ROM?
-
@sleve_mcdichael Taking a look at the script, it seems as if I can set a
%rom%
parameter so$1
can be the chosen file. Is that correct? -
@sleve_mcdichael Using the second script, no errors are outputted, however it doesn't load the game.
-
@RetroFloppy08 can I ask, what's the end goal here?
-
@sleve_mcdichael Detecting specific file types and loading the emulator associated with it. CHD files I have reserved for PSX games.
-
@sleve_mcdichael What argument am I supposed to attach to the command to load the filename?

You mean only load PSX .CHD filetypes directly from the CLI, with your script, without using emulationstation, right ?

You can reduce it to :
#!/bin/bash [[ $1 == *.chd ]] && /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx $1
Save it as a file, for example : loadpsx.sh
Then do :
bash loadpsx.sh /home/pi/RetroPie/roms/psx/game.chd
I think runcommand.sh needs the full path.If you want to reduce it to, lets say : bash loadpsx.sh game.chd
Then you have to add the path in the script. -
@Folly When I click on a ROM in the system I specified to use the script, I want it to determine what runcommand command is appropriate based on the extension, and give the command. I have reserved .chd files for PSX, as those files aren't specific to one system.
-
@RetroFloppy08 Furthermore, if the check for a PSX game (as an example) fails, it moves on to checking for another system (eg. SNES) and so on and so forth.
-
@RetroFloppy08 The main reason i'm attempting this is because of a project i've been working on that aims to get game disc support on RetroPie. I've worked out mounting and loading the contents of the disc, and remounting it after a swap, but so far the only system properly supported is PSX, as there exists no pre-made way to detect file types and run the corresponding emulator.

Ok, I read your post.
Really not sure what you are trying to do here.
Basically you want to detect filetype and the run the appropriate runcommand.Perhaps this is something to look at (read lines 66-83) :
https://github.com/FollyMaddy/RetroPie-Share/blob/main/00-scriptmodules-00/emulators/b-em-allegro4.sh
On the extentsion it detects whether it's a tape or a disk and loads the appropriate commands.Looks like this is somewhat you want to do.
-
@Folly Basically:
-User selects ROM from EmulationStation
-Custom script runs in place of runcommand.sh (thanks, es_systems.cfg)
-Custom script detects file extension, then uses runcommand.sh to load the correct emulator -
Well look at my earlier post.
It runs that multiload.sh with the runcommand.sh and then the multiload.sh script does the rest without using runcommand.sh.
-
@Folly Looking at the link, it's not exactly what i'm looking for. I shouldn't need too much code, just some if else statements.
-
And did you try the suggestions earlier in the thread ?
-
@RetroFloppy08 Of course, I would need some kind of way to load the ROM's filename in question. That's the problem i'm facing currently.
-
From the CLI or from emulationstation ?
