I don't know if any one has picked up on this, but I've been replacing the low res logos in my collection with higher quality ones, and during the process, as of the last 2 betas, images have been getting corrupted upon refreshing (maybe refreshing caused it? I'm not 100% sure). The worry is if there are dozens of images (or more) across the collection like this without me knowing. I've uploaded an example. I had to zip it up because it wasn't letting me upload it straight for some reason.

I can't say that this *isn't* our fault, but it is unlikely that LaunchBox is corrupting the file in this way. Might be worth doing a health check on your drive or looking what else might be touching the files.

That said, just in case, a few questions for you. What is the drive these are stored on? Internal, USB, NAS, cloud, etc.? What do you mean by 'refreshing'?

I'll look at the code, but so far all I see is that we do full file copes/etc.. Your files ended up with a bad block in the middle so that doesn't match what I'm seeing in the code.

@MysterNybble This beta seems a lot faster and smoother!! Nice work!! I previously mentioned in the last beta my screen freezing in Bigbox but not crashing back to desktop like it used to do. It just did it again but if I click the mouse buttons it regains focus. There was no WER file but here are my Launchbox files.

This has also been happening since the last beta. Not a huge deal but curious. Every time I start a game after booting up the first time it takes a long time to boot them ok after that.  See video. 

Thanks for the logs. According to them, Big Box didn't freeze this time. Around 9:20pm in the logs, while attract mode was running, something else took focus, which pauses the music and videos, and Big Box came back when you clicked a few minutes later. Nothing in the in the logs so it's possible something else grabbed focus. Anything else running on that cabinet (Steam, LEDBlinky, controller software, Xbox Game Bar, whoknowswhat)?

For the slow launch, the loading screen normally closes when the game's window appears, so the black part looks like it could be MAME itself starting up, perhaps waiting for some drives to spin up? If you send the logs from one of these where it happens? Do you know if this is new for 14.1 betas or was it happening in 14.0/before as well?

@skizzosjt, @AzgoRAth, @JoeViking245 - quick update, I think I sorted out the last platform loading thing in a way that should be better for everyone. Stay tuned for the next beta!

@MysterNybble : I took a screenvid of it happening. (the platform revert to ALL or in my case now to the first one in my list of platforms)
In the screensnap u can see me in launchbox. I selected the Apple II platform, clicked on a few 3D boxes.
Then I closed Launchbox. And waiting a few seconds and launched Launchbox again.

After launchbox starts, it defaults to the Apple II platform but after that immediately goes back to the first platform in my list...which is the 3DO.
(I had ALL deactivated cause it bothered me that it always defaulted to my largest view)

And u can see...my mouse stays where it is, it does it on its own.
So it does remember my last platform...but somehow forgets about it and defaults to the first one.
So somewhere in your code, after it reads the last platform from xml settings and after startup u have start your search there I suppose.

No idea why this happens. Never had this before in any of the other versions before 14.1

That is odd and different from the other last platform bug. Obviously, something is resetting the selection after you load. Can you see what plugins you have installed from the community and let me know what those are. Also send me Debug logs if you have them while this is happening in case that is useful.

+1 on the WTF fast on the exit or switch between Launchbox and Bigbox!  Congratz, this was an annoying one for a long time!

Also, I just noticed a weird behavior with 3D rendered boxes, (not sure if it was in previous beta), using default theme in Bigbox with a view supposed to render 3D boxes, some works when other just stick to the 2D box image. It happens on different games even under the same platform. I didn't notice any config difference.

My assumption is it's related to the images you have for different games. Can you confirm a few things:

• Is it consistent (i.e. same game always works or doesn't) or more random?
• What are some games it doesn't work on?
• Can you compare the images you have for those that work versus not and see if anything is different?
• Where did you source your imagery from?

Thanks!

I'm testing in Big Box on my Windows 10 system with a 120Hz display just for reference. It's where I've done all this testing previously.
With the experimental checkbox disabled, no change, performance is not up to par relative to WMP.
With the experimental checkbox ENABLED, I think it's ironed out! VLC playback performance is now ON PAR with WMP! Including fullscreen playback at that!
Just making that a point that the option is definitely making a difference this time around. 👍

 

 

Performance improvements are immediately noticeable for boots going between LB and BB 👍

 

 

Also been doing lots of these boots back and forth. None have gotten stuck on "Loading Interface..."
I'm hopeful this issue will not be rearing its head anymore! 👍

 

Badges look crisp and clean now in LB, no longer jaggy-like or pixelated. 👍

 

 

Missing status for Steam games installed on disconnected disks/paths working as intended. The tool tip that pops up shows the proper path of where the game lives on the disconnected disk. 👍

@MysterNybble Wow! Great work! Rom import only took seconds first try. So nice to have this working again.

Awesome to hear :-D. I'd much rather my beta threads be filled with these sorts of comments.

With your comment I decided to clear out my plugins directory, started with NO plugins and testing it by placing several of them back in.
Turns out I found the culprit which caused this behavior.

And it was the eXoPlugin that caused it.
When it's not there...then LB behaves as it should.
Once I put it back in, it causes the platform to revert back to the first one.

So, not sure what to do with this. Cause it is the latest version of that plugin.

I'll say this but I didn't think it was relevant as it was only happening on the betas, and not the stable releases. I am currently running my LB setup on an external USB drive. Maybe it has been disconnecting and causing it? But it doesn't explain me only seeing this happen when I update to betas, and only some betas. Beta 1 and 2 I believe were fine. I'm just not sure, but for now I'm backing up whatever I've got.

When I update Launchbox to version-14.1-beta-3 I cannot import newly installed games from Epic games storefront they seem not be able to detect any games anymore.
If I downgrade my Launchbox back to 14.0 and from there update up to LaunchBox-14.0.1 all seems fine again and can import my games from the storefront just fine.

@MysterNybble Thank you for your help and quick response.

However, I've noticed it's far from perfect. I've attached a screenshot showing how it looks in the beta version and how it looks after adjusting the DPI setting on Launchbox.exe via the compatibility settings.
After the change to the .exe file, things are much clearer. This is how it was before the update to 14.0. Could you please take another look at it?

Thank you very much for your effort.

Quite a week but Beta 3 is finally out!

Thanks again to everyone testing these betas. This beta is inspired quite heavily by feedback here and from our bug reporting tools So thanks for your reports, logs, and back-and-forth.

tl;dr; imports no longer stall on "Saving games", closing LaunchBox no longer shrinks your mouse pointer, cloud sync stops inflating play time, badges are sharp again on high-DPI screens, quick filters can exclude values, RetroAchievements is now a managed plugin, Save Management restores are a lot safer, and the usual pile of fixes

FIXES FROM THIS THREAD

• "Saving games" for-ev-er: The first import would sit on "Saving games" for minutes. @xmas, @JoeViking245, @SqHd report back if this seems better, the same, worse?!
• The Incredible Shrinking Mouse Pointer: Is no longer out in theaters. @Drybonz, @launchretrogirl2562, @dukdukgoos, @eMonster420 lemme know!
• Cloud sync loves Animal Crossing: a bug in beta 2, fixed in beta 3. @Hanz this is fixed going forward, I'll need to sort out the bad data on our servers though.
• Blurry Badges we don't need no stinking Blurry Badges: fixed, was  14.0 bug, fixed here. @Kedog
• Help > Fine Don't Help: button no goes to the right place @xmas
• "Applying metadata" for-ev-er Part 2: The progress bar no longer gets stuck after the database update, and automatic imports no longer interrupt you with a metadata download prompt @JoeViking245
• Curious case of Edit Game media: title cap changes, swapping image types deleting images, and prev > < next issues @xmas this has a chance of fixing the Alternate Names "file in use" error you reported as well

Thanks for Beta 3! Quick report:

Help > Report Issue: works perfectly now. Sign-in goes through and opens right away. Thanks!

“Saving games” delay: fixed. The first import now goes straight through with no stall. The attached debug log shows the finish phase taking super fast!

Import target platform: still intermittent. When I drag & drop ROMs onto a custom platform, the wizard defaults to the “Scrape As” platform instead. For example, Nintendo Famicom (KR) → Nintendo Entertainment System, and Nintendo Super Famicom [xmas Set] → Super Nintendo Entertainment System.

What I’ve found so far:

• Title/Scrape As, platform details, game folders and emulator associations are set up the same way on working and failing platforms. Filling in all the platform details made no difference.
• Disc-based custom platforms (PS (KR), PS2 (KR), Dreamcast (JP)) have always kept the custom name. I tested .m3u, .gdi, .chd, .cue and .bin on Dreamcast (JP).
• It seems to be stateful. Today, Super Famicom [xmas Set] kept defaulting to SNES. Then I dropped a zipped .sfc onto it, and it correctly showed [xmas Set]. After that, the plain .sfc also showed [xmas Set], even after restarting LaunchBox. I cancelled these imports, so nothing was actually imported.
• I’ve seen it fix itself like this before and then go back to the “Scrape As” platform later, so I expect it to come back. It feels like the wizard remembers a previous platform choice somewhere and uses that over the platform I dropped onto.

The debug log doesn’t seem to show how the default target is picked, so a log line there in the next beta would help. I’ll send a log when it reverts again.

Alternate Names “file in use” error: still there, with a pattern. It only appears once per Edit Game window. If I keep the window open and move to the next game with the arrows, it doesn’t appear again until I close and reopen the window. It’s also intermittent, even within the same platform. I’ll send a log the next time it happens.

One small note on my earlier suggestions: I use Alternate Names a lot because many of my games have Japanese/Korean titles. A smoother Enter → “Set Selected Name as Title” flow and Next/Previous shortcuts in Edit Game would really help non-English libraries. Just sharing the use case.

Thanks again!

Not to 'pimp my gig' on the beta thread, but there's a plugin that may be able to help with that.
