My mistake - thanks for pointing that out!

The author is here - Pacman56

Lordmonkus - my machine is: intel i7-6700HQ CPU @2.60GHz / 16GB RAM / AMD Radeon Pro 450 / SSD / 64bit Windows10. 6100 games total in LB, around 4500 of which are the troublesome MAME ones. Same issue in BB - other systems work absolutely fine, arcade/MAME section runs slow. I took a look at the "speeding up LB performence" link. I don't think that the problem is with my PC's performance - everything else is absolutely fine (including the other systems in LB). It doesn't seem like a performance issue that I am experiencing. It seems that something is going wrong with the LB behaviour at this point. As you had initially advised, I did/do think that the problem may have been with the Lightspeed importer. I followed your instructions to reverse the process though wonder if there is anything else I maybe should have done in that regard?

ckp - yeah, I'm familiar with the issues around cacheing, though this just didn't seem to be a cacheing issue to me. LB itself was misbehaving - stalling/going full screen/not responding every few seconds. I had previously left it on overnight to see if it WAS a cacheing issue, though in the morning it was exactly the same with no extra art having appeared.

Seeing as Rocketlauncher is the universal launcher & ROM manager, it would be better if the frontends (including Launchbox) could read the media data from Rocketlauncher, rather than the other way round.

I am also keen to see if this issue is resolved. Surely we can access the same manuals both from within Rocketlauncher/Pause, and Launchbox/BB?

Can you get it work where inside the platform folders, the manuals are within their own game subfolders? This is how Rocketlauncher seems to like it, and I don't want to take them all out of the subfolders and break Rocketlauncher.

OK....do you have any suggestions? Is there somewhere I can get help with this?

Thanks Lordmonkus - but if it was my system, wouldn't the other emulated systems be affected too?

Evidently! Any advice on how to investigate/fix this? The other systems I have so far (MSDOS/exodos, NES and SNES) are fine.

I just added them the way you described above (and without downloading any metadata or images) - and I am having the exact same problem! Launchbox keeps freezing every few seconds, making it impossible to navigate!

Thanks so much Lordmonkus. LB running OK again with those removed. I will add them via the above method tonight.

There should be some sort of fund for this eXo! Do you pay for it all yourself or do you have donations etc?

Many thanks for your reply. As it happens, the problem appears to have resolved itself spontaneously (as far as I can tell). If it recurs, I will take heed of the above! Cheers

I set MAMEUI64 to scan my MAME rom directory - it takes around 30 minutes due to the number of files and metadata. However, when I close and re-open MAMEUI64, all the roms are gone - it doesn't seem to remember the roms!! I have to scan it again, which takes ages! Is there a way to get it to remember the scan?

Easy money for someone

I too would like to know the answer to the above.

So....is there a retro arch core for AAE?

Well, I went ahead and imported around 3500 MAME roms via Lightspeed, split into separate systems. And Launchbox (and BB) have become unuseably slow! I thought that maybe it was a cacheing issue, but after leaving it overnight, the issue remains. LB keeps becoming non-responsive every time I try and do something with it

Well, I left it overnight, hoping that it was just cacheing images or something - and the exact same situation this morning For reference, I didn't use the latest version of Lightspeed but a previous one, as we are recommended to do in the lightspeed thread. Having read the above few posts, my next questions are; - how can i "undo" what Lightspeed has done? - how can I import MAME into LB with splitting into the various arcade categories like Lightspeed does?

Interesting....so maybe letting it run overnight will remedy the issue after all?

It's causing major issues - LB goes into not responding every 10 seconds or so and every game is taking ages to appear in LB. To be clear - the laptop is running fine - other apps run at normal speed. It's only LB which is going into a seizure Going to bed now so will leave it on overnight. Hopefully it will be sorted by the morning.

Do you have to scroll through them all or is there a way to make LB do it in the background? Scrolling would take hours at this rate!

OK....leave it on overnight kind of thing? It would be handy if LB gave some indication of what it was doing behind the scenes (e.g. cacheing), rather than leaving the user to guess.

I just imported a bunch of MAME roms & metadata via the Lightspeed importer. 3473 games in all, split into a few different arcade systems. Problem is, LB has since become so slow it is unuseable. After clicking on a platform there is about a 15-20 second delay before the games appear, and then they load slowly one by one. LB intermittently shows as "not responding" on Windows resource monitor, though CPU usage for LB is not particulalry high. Big Box is also correspondingly slow. The NES and SNES consoles I already had in LB are about the same speed as before I think (some manageable delay in LB, but no delay in BB). Any help appeciated!!
