ScummVM lag with joystick control

Dominus

Has anyone figured out just a quick fix for this? On my Pi 2 everything ran perfect with ScummVM, but now with a Pi 3 and 4.0, the 360 controller lags horribly for this, and makes point and click games (with the controller) unbearable! I don't want to go about mapping things, as I'm making this for my younger brother and I don't want him to have to worry about fixing it or changing it if he wants to play other games and no mouse/keyboard either would be nice, just wireless 360 controllers.

I haven't found an simple solution for this. You said you don't want to use mapping, but I followed the tutorial from @mediamogul and had it working in a bit more than an hour. ScummVm now works perfectly without "fixing and changing" anything. No conflicts with other emulators too.

Has anyone tried to just put the old ScummVM onto Pi? Is that even possible? I just don't understand how it can work great with the previous version, now it lags horribly and is unplayable?

@Dominus I copied a ScummVM binary, version 1.7.0, from a previous RetroPie build to replace the latest one, version 1.8.1. I'm using a PS3 controller and version 1.7.0 works fine.

In building version 1.7.0, I had edited the code to remap the buttons for the Dualshock so using the old binary just seems the easiest solution for now.

Dominus

@dudleydes I use a 360 wireless controller so I should just be able to copy the binary from a previous install, install it and be good?

dudleydes

@Dominus Yes, you should be. I copied the binary using the sudo cp command. There was no installation as such.

I did have an issues with the GUI themes. The Modern (orange and yellow) theme wasn't working, just the Classic (green and black) one. This is easy to fix if you run into the same issue.

Download the Modern theme, scummmodern.zip, from the ScummVM github page. Note that this is for version 1.7.0. If you are using a different version, then make sure you choose the appropriate branch.

Transfer the zip file to your pi. Launch ScummVM from ES and select Options. In the Paths tab, you can choose the Theme Path (the location of scummmodern.zip) and in the Misc tab, you can choose your theme by pressing the Theme button.

Dominus

So I should just be able to copy /opt/retropie/emulators/scummvm/bin/scummvm from an old install and replace it on my current one?

Dominus

@dudleydes Hmm I tried my above method but it didn't work. Where do I find the binary? or is there more files to copy over?

dudleydes

@Dominus Strange. I copied the ScummVM binary from the location you mentioned on a previous build to the home directory on the latest build. Then I ran the following command to copy the binary to the correct location:

sudo cp scummvm /opt/retropie/emulators/scummvm/bin/scummvm

That was it. I ran the +Start ScummVM script and version 1.7.0 launched without issue except for the classic GUI theme being used as outlined above.

@herb_fargus Has this been fixed with the 4.1 release? How do I just copy an older version of ScummVM over to a new version of RetroPie?

Dominus

Any help with this yet? :-(

darkav

I have the same problem. Any news on this?

Dominus

What I did was took all the scummvm folders I could find in an older version. (I think it was the 3.7 image?) Just WinSCP over and copy all of the /opt/retropie/emulators/scummvm files. Save to your desktop and then load up your newest image and replace the files. Pretty sure this will work. I thought there might have been another folder to copy, but I don't think that one mattered. Let me know if it works for you. I just made a new image, so when I have time I'll have to do it again anyway.

@Dominus Tested with the one in Retropie v3.7 => ScummVM 1.8.1pre
Same issue.
Now i will try with an older version...

darkav

OK, with SCUMMVM 1.7.0 works. Can be taken from Retropie v3.6.

Dominus

@darkav Ok good to know! Maybe eventually they'll just scrap the updated Scumm and go back to the older version? or just fix the problem in future versions.

@Dominus We don't maintain/develop every piece of software we include with RetroPie - the joystick control issue has happened since we are building scummvm on SDL2. Not sure if they still include SDL1 support, but the issue needs to be fixed either at the scummvm project or via SDL2.

It has been brought up here - http://forums.scummvm.org/viewtopic.php?p=83050

i may consider including an older scummvm at some point, but you can probably work around it by using xboxdrv or by using a wireless keyboard with mouse/pad etc.

@BuZz

Can we take this to mean that the older version would be considered as an alternative installation? I would hate to lose the current and future advancements this software has to offer in favor of alleviating this one issue.

BuZz

@mediamogul yeah - it wouldn't be default or anything.

mediamogul

@BuZz

Ah, fantastic!

@Dominus, @darkav

I'm sure that you've both read above about the ability to use xboxdrv to solve this issue. I do recognize that the learning curve for the utility is high and that it's not even always an option. Once I get some spare time to sit down with it, I plan on revising the guide with a simpler approach to it's use that may appeal to more people. However, if you're interested, an example and work-through of this new approach can be found here in the mean time.
