Hello

I have retropie 4.5.1, running on a pi 3. I do have a clarification question re folder and .svm naming please. Using scummvm (not the Lr version) I used the built in GUI to mass add, and it created a number of .svm files in the root of the roms/scrummvm/ folder as expected. Full throttle and other games work, when called from the ES menu and gamelist.xml.

I've got an .svm file meeting the spec above in each folder. ie, ft.svm for full throttle.

However loading the same game using lr-scummvm, the game just exits back to the ES menu.

I'm wondering if I have misintepreted the folder naming. Should the game folder name match the scummvm shortname i.e. roms/scrummvm/ft.svm, or, roms/scummvm/Full-Throttle(English Version).svm

which is correct?

..and could someone confirm if my same gamelist.xml will work for both scummvm AND lr-scummvm?

thanks for any help! TIA

@iainjh hi ! see some clarifications below.

The directory of the game does not need to have the short name and in fact does not strictly need to have the .svm extension either. Adding the .svm extension is only required for EmulationStation to launch the game directly by selecting the game folder and not having to go inside it and select the shortname.svm file.
The shortname.svm file inside the game directory with shortname inside the file is required for the lr-scummvm core to recognise the game.
When you use the standalone scummvm (not the lr- core), the .svm files get created in $romdir/scummvm, not inside each game directory. Unfortunately these do not work for the lr- core and you will have to create them inside each game directory in addition to the ones outside.
Having both emulators at the same time means you will have duplicate entries in EmulationStation, one for the top-level .svm files for standalone scummvm and another for the game directory containing the .svm file inside for the lr-scummvm core.
Right now there is no way (afaik) to have an unified system for both (but read below).

There is a very recent PR for lr-scummvm that will add support for autodetecting the game according to the gamefiles inside the game directory. This will make adding the shortname.svm file inside each game directory obsolete (point 2 above).

When that PR is merged I will be working on integrating that functionality and will revisit an approach to have both emulators (standalone and lr- core) to co-exist with the same game directories. For now, just be patient :)

thank you!

I'll now have a play at resolving my setup issue, thanks for the explanation and pointers for the future

thanks again :)

Thanks for lr-scummvm! It works almost perfect on my Raspberry Pi3B+ based table top arcade cabinet. (so no keyboard, just joystick and buttons).
I'm running version 2.1 on Retropie 4.5 and have a few questions/feature requests.

Is it possible to remove the quit and return to launcher options from the lr-scummvm menu?
My kids are also using lr-scummvm and I don't want them to enter the scumm-vm launcher or the retroarch options.
I start the games from the retropie menu (works really great with the .svm files) and I want my kids to quit the game by simply pressing my hotkey button combination to return to retropie.
So it would be great if I could remove the quit and return to launcher option from the menu, or change the behaviour of those two options to return directly to retopie.
I don't want to remove the scmummvm menu completely, because I need the menu to load and save progress of the games.
Even better would be if those two options would be removed when choosing the retropie Kiosk Mode.

I also noticed a few performance issues.

Freddi Fish 5: Sound is stuttering and slow. Is this caused by the color depth?
Kings Quest 7: Same issue. Stuttering sound and slow. Also caused by color depth?

Is there a way to improve performance on those games? I already did the speed hack option.

Regards,

Rene

Thanks for lr-scummvm, it works almost perfectly for me and made my life so much easier over using scummvm (no lr-).

I do have an issue, which I described in the following post and was hoping for help: https://retropie.org.uk/forum/topic/26925/blade-runner-overlay-transparency-issue-with-lr-scummvm

@kleingeld no need to post here then also.

@BuZz sorry, I was hoping to get the creator's attention this way. Won't do it again.

@hhromic said in lr-scummvm: request for comments and testing:

lr-scummvm core t

I am in the middle of testing this with a PS Classic (using Emulation Station built into Project ERIS/RetroArch). I have it working fine but ES sees the game as a directory I have to click into and launch the game.

I tried reading as much as I could and tested out editing the xml file.
I added .svm to the directory and made sure that the short name.svm file was inside the directory with the correct short name.

The only thing im not sure about is the core im using.

But adding games to the scummvm directory works fine.
Using the scraper works fine, but shows the meta data for the launcher file and not the directory.

When I change the set up to how you describe the game launches and then goes back to ES with no error, just fades back to the game select.
I dont really mind having to click and then click again but for my OCD id love to get it working... searching i found your advice and tried that straight away but the games dont launch.

Is there anyway I can check I have the correct/best core?
Should this work in the PS Classic or is it strictly for RetroPie?

Its just annoying that the games i add all work bar it showing them as a directory ha!
So far I have tested:

Beneath a Steel Sky
Broken Sword 1 and 2
Full Throttle
Day of the Tentacle
Discworld 1 and 2
Monkey Island (Curse, Secret, Revenge)

Cheers :)

Hello everybody,

i'm testing the latest version of lr-scummvm with lucas arts adventure, unfortunately i've found out that cd audio soundtrack dosn't work for fot the secret of monkey island and for the day of the tentacle and sam and max hit the road when characters talk you just ear a rumor at the beginning of each every phrase and then it's all silence (i'm using the italian version of the game if does it matter but on pc the same games works flawlessly)
am i missing something? some setting to change or some package to install? thanks

Darksavior

@drmirva Check your cue file. The pi is case-sensitive.

drmirva

@Darksavior there is no cue file (and never was for scummvm)

BadFurDay

@drmirva with the soundtrack the files should just be "track 1" and so on in the game folder. My suspicion is that both those audio files and the voice files (for Day of the Tentacle and Sam and Max they are called "Monster") may be using a format your pi doesn't have a codec for. Possibly OGG Vorbis (the soundtrack files will be .ogg and the monster files will be .sog). I had the same issue and converted them all to mp3 instead. See section 7.8 here:

https://raw.githubusercontent.com/scummvm/scummvm/v1.8.0/README

drmirva

@BadFurDay you were right seems that it doesn't support ogg file, wich library i've to installo to make lr-scummvm use .sog file?

BadFurDay

@drmirva possibly vorbis tools but I'm not sure, as I said I converted them to mp3 format instead as I've done that before, been using ScummVM since it only supported Lucasarts games, never sorted ogg vorbis on the pi though.

sudo apt-get install vorbis-tools

Has anyone had any luck getting Phantasmagoria 2 to run on lr-scummvm? It runs fine under scummvm, but when I try to run it with lr-scummvm it just crashes back to ES.

hello, first of all the application has worked for me without problems on an Rpi3B +, I have only had one problem and that is that I cannot change the language in some games, for example in beneath a steel sky that supports several languages, I want to leave it with text in Spanish and I haven't found a way to do it.

Edit: nevermind, I already found the answer, I just had to create a subscript in the scummvm.ini file and add the language parameter.

the only ones that don't work are the discworlds, but I can change the language in the menu or force it by deleting the other language files.

BadFurDay

@corezon lr-scummvm is an older version of the program itself, 2.1.0. Check compatibility on the official ScummVM website, the game might only be for 2.2.0 or even the development branch.

Edit: I've just had a check and it should work on 2.1.0 so it's not that.

Has anyone seen about this edit someone has made of the lr-scummvm core? https://github.com/diablodiab/scummvm

I don't quite understand it but I think the dev is saying he's edited the scummvm core so it's updated to 2.3.0 and has simplified it so it's easier to update to the newer scummvm version for retroarch?

I had a quick try but I hit the scummvm-libretro.so not found error, which someone mentioned further above can be due to a discrepancy in the makefile file in /backends/platform/libretro/build.

So if anyone smarter than me wants to take a dive with this and see if they can get this updated version of lr-scummvm working on pi4 let me know if they can figure it out.
