And suddenly no ScummVM Games are working...

windg

Ok, i try with a RPi3 B+ this time. I did a clean install of the latest RetroPie and i did all the latest updates.

I can confirm the issue. The same roms that are working in RPi4 they don't work with RPi3. I test all combination of Graphic mode and 3D rendering engine and the games are crashing back to ES. Also, when i try to change the graphic mode to opengl, scummvm is crashing back to ES.

I try also a backup (9 weeks old) of RetroPie it have scummvm 2.7.0. Here the games are working if i change to opengl and software, and they are stll working if update the system. I am a little confused.

Maybe the issue is with the scummvm.ini file. When i change the Graphic mode from global menu, the change didn't saved. Also, when i change the gaphic mode, when i add the game, the game will work only from created shortcut.

I add manually to the scummvm.ini file those parameters and now the games are working, from menu and from shortcut :

gfx_mode=opengl
renderer=software

First of all, thank you for taking the time and trouble to understand the problem!

It worked for me too, it's unbelievable that the solution was so "simple". I'm also relieved that I don't have to do a reinstallation, etc. phew And strange that there is this difference between the Pi 3 and the Pi 4, would that be a case for a bug report?

Funny: The games I installed lr-scummvm for now also run with the new "normal" version :)

I have still one question. In some games (including ScummVM) I notice that some stutters or videos do not play smoothly. That's why I'm considering buying a Pi 400, also because of the form factor and the integrated keyboard.

Is it possible to keep the four backup directories (rom, config, bios, scans) of my Pi 3 installation in sync with the 400 because I have two Pi installations and would like to continue using them. So one runs on the 400 and one on the 3B and I sync the folders? Or are these not compatible between the 3 and the 4?

No, why ? They're different systems with different GPU drivers and different capabilities.

I don't think this is related.

I don't know if this is a bug. The only thing that i find strange was that my changes in global mode didn't saved. To be sure, i did 2 clean installs with the same result and the most weird is that my older back up don't have this behavior.

With what game do you have issues? If you have the slowdowns with lr-scummvm then yes, this emulator doesn't run some games in full speed, even in Pi 400.

Is it possible to keep the four backup directories (rom, config, bios, scans) of my Pi 3 installation in sync with the 400 because I have two Pi installations and would like to continue using them.

You will not have problem with roms, scans, bios but i am not sure about configs.

@mitu So you don't think that the described ScummVM crash is due to a bug in the version you're using?

As for the games. All I can say is that at the time all but three games were running on the "normal" version of ScummVM. Then I installed lr-scummvm for the three games. Then I did a system update (incl. ScummVM update), then suddenly no more games ran in ScummVM and after the tip with the manual addition in the scummvm.ini all games are now running again including the three games in the normal version.

Where would you rather suspect the error if not in ScummVM?

@windg The games I had problem with stuttering videos are for example Zork Inquisitor or Kyrandia 3 (GOG).

I thought its a bug, because ScummVM crashes to ES, while startging games and after changing options in PI 3. But yes, that doesn't have to be a bug.

@10vorne Ι try Zork - Grand Inquisitor (DVD Windows) with a Pi 400 and scummvm v2.7.0, the intro videos and in game animations are all smooth.

@windg I do think that the 400 is noticeable in some games / emulators in terms of performance. I hope especially with the N64.

But first I have to know / clarify whether I can continue to use my Pi 3 installation that has been built up for a long time, or what I lose if I cannot take over the config folder. What is stored in it? The scrape info? Or is all the information on this stored in scans/?

And if I think about it, there would be problems anyway, because then I can no longer sync in the future, because one of the two installations would be my reference, which I mirror / synchronize to the other installation. So I would have to switch both to the 4er anyway... ^^

@10vorne
You will found the info about scraper media paths here : https://retropie.org.uk/docs/Scraper/

Of course it is possible to copy the configs folder. Inside you will find configuration files about emulators, retroarch,controllers, emulationstation and some others important files.

You can read about backup options here : https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup-option-2
