es_systems.cfg systems file extensions and rom filenames

mitu

The fix was added to the -dev branch, if you update from source emulationstation-dev, then you can check if it solves the issue.

@mitu thank you for all your time and replies!

@mitu
exited ES
I have compiled the -dev 1h ago.
2.12.0rp-dev
I see the commit about checking xml and extensions

I have deleted the gamelist.xml from
"\configs\all\emulationstation\gamelists\ags"
(just a note, ES not recreating new xml at quit and start it again.
When is it supposed to recreate an xml in above? )

Started ES with only .exe in es_systems.cfg for ags
As said no xml on above path, ES still shows both exe and .EXE files (.EXE removed)

So if no xml either in roms or es xml both extensions show.

NOTE
I run with debug an i see below. Is this normal when ags is valid platform and correct in the es_systems.cfg?
"Oct 08 20:17:28 lvl1: Unknown platform for system "ags" (platform "ags" from list "ags")"

Are you sure you don't have an additional gamelist in the ROMs folder (ags) ?

Is your ROM folder on the sdcard or it's using a USB stick ?

The scraper doesn't have ags registered as a known scraping platform, probably because none of the scrapers offer it as a separate system/platform. That's ok.

@mitu hello!

No gamelist whatsoever.
I delete the ES xmls with a script except the retropie one that has the menu
This thing about ES not creating his auto xml after deletion of existing xml, isnt new behavior to me but not bothered me as in the final tests i use scraped xml

Test rom is on sd card. not using usb.
Ags test game is in subfolder due to multiple files (like a dos game). There are 2 exe which one is with .EXE extension

But when I need to test if a system working I just drop a simple file to test or in this case a game folder

Noted on the error.

mitu

Hm, this seems to be a different 'bug' - extension seems to be is case-insensitive. We can also categorize it as an 'accidental enhancement' since it allows us to list the extension just once.

I'll take a look to see if it's intentional or not.

Yes, it seems intentional:

when the list of extensions is populated, they're lower-cased and put in the list - https://github.com/RetroPie/EmulationStation/blob/2fd3a78e5297d24781b2eb89c76210eec054c0a2/es-app/src/SystemData.cpp#L190
when a system's folder is read and the gamelist is populated, each file extension is lower-cased first - https://github.com/RetroPie/EmulationStation/blob/2fd3a78e5297d24781b2eb89c76210eec054c0a2/es-app/src/SystemData.cpp#L108C81-L108C81

So it's not possible to add .exe and exclude .EXE. It's probably better for Linux or other systems where the filesystem is case-sensitive, the extensions of the files don't need to be an exact match (i.e. lowercase only).

2Play

@mitu tx again for looking into it.
So the reason its working with xml specifics can be ignored as per your patch above.

Maybe this is why not noticed when you have no xml and just roms

To pick you brains, about the ES xml auto creation mentioned above.
When these are supposed to be created automatically from ES.
A complete change in the rom folder?
Is there a cached location of these?

My regards

2Play

@mitu Do you think, in the future, a condition can be included (as an enhancement) in the source code, so if OS is linux based (case-sensitive), ES to read/skip systems extensions accordingly?

mitu

@2Play I don't know, but I kind of agree with the current behavior.

@2Play said in es_systems.cfg systems file extensions and rom filenames:

The XML is written at end of runtime (when you exit EmulationStation.) Entries will be written for any game whose information was added or updated during the preceding runtime including last played and playcount information.

Example: you have a folder with:

Legend of Fitzgerald
Super Maōri Brothers
Tremendous Man

...in your XML it only has Legend of Fitzgerald and Super Maōri Brothers.

You start up ES. You play Tremendous Man once, and then you go into the menu and fix the wrong name of Super Zulu Brothers to what it should be.

Nothing happens yet. Later, you quit ES or restart the system. Now, the XML is written. A new entry is created for Tremendous Man, and an updated entry for Super Zulu Brothers, overwriting the previous Super Maōri Brothers entry. Now the XML has entries for all three.

2Play

@sleve_mcdichael tx for you feedback. So restart ES isnt enough in my understanding
Full restart will be needed after the change.

FYR If i delete the ES xml and restart the system it doesnt create a new one to replace deleted one, just displays the filenames though

Do you know if its using a cached location somewhere

No, as @sleve_mcdichael said:

Entries will be written for any game whose information was added or updated during the preceding runtime including last played and playcount information.

You need to play at least a game, so that it's info is changed and will be persisted on exit. If you don't play any game, then ES considers nothing changed so it doesn't need to save anything. Instead of playing a game you can also just mark it as favorite or scrape it so that its info changes.

2Play

@mitu uh ok. just thought it wasnt really a requirement.
Ill test soonest possible

2Play

@mitu Tried the favorite trick and works as you both advised.

Now ill check the es dev again

2Play

@mitu
Tested below:

I have applied the 2.12.0.rp binary of ES
In roms/ags there are 2 exe files as per image
In roms/ags applied below test gamelist.xml

<?xml version="1.0"?>
<gameList>
	<game>
		<path>./Apprentice 1 Deluxe/App.exe</path>
		<name>App</name>
		<favorite>true</favorite>
	</game>
</gameList>

es_systems.cfg has only .exe

<system>
    <name>ags</name>
    <fullname>Adventure Game Studio</fullname>
    <path>/home/pi/RetroPie/roms/ags</path>
    <extension>.exe</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ ags %ROM%</command>
    <platform>ags</platform>
    <theme>ags</theme>
  </system>

Result in ES
ES Version and the 2 games show behind on above test.

Should I recompile? Shouldnt with xml the file with capitals .EXE to be omitted from being displayed with the bug fix?

No, and I'm confused why you'd think it would.

2Play

@mitu
My understanding was that what the bug fix would do.
"Gamelist bugfix: don't show un-registered extensions"

I thought that on the dev binary it would do this. Or the fix expects to see both in the xml and then exclude what is not in es_systems.cfg

For Reference
In the past, on pi3,4 if you wanted to hide a rom file from showing in the ES gamelist, you just removed the extension and these were not displayed any more

Its a practice many used the past years by changing the extension to CAPITAL letters and then remove from the es_systems.cfg

I ll try to dig up an older binary for pi4 that I used in same way and provide you the version

It does that, but - as I explained later on - extension search is case-insensitive so if you add .exe, then .EXE is also matched even if not listed.

I ll try to dig up an older binary for pi4 that I used in same way and provide you the version

Sure, let me know the version and I'll check.

2Play

@mitu found it!
2.9.3RP has this feature. Seems changed from 2.10 onwards?

NOTE: 2.9.6rp had the bug with the video screensaver not starting a rom any more which I see it got fixed in current version

To our discussion:
I have in ags, exactly as I wrote in https://retropie.org.uk/forum/post/291385 2h ago

es_systems only .exe extension
ags/subfolder game/.exe .EXE the files

if i rename both to .exe they both show. once I rename the unwanted winsetup with .EXE it hides
(no gamelist.xml whatsoever used)
